I ended up with 3 portable welders with various electrical issues. Let's see if we can fix them! Ask a question here: / watchweswork grypmat.com use code: watchweswork10
As an Electrical Engineer, I can say your debugging skills are right on track. Great job. Electrolytic caps have known aging issues, and do need to be replaced from time to time in older equipment. Given the welder is 25 years old, it is getting to that age where some of the caps will start to go bad. You definitely NEVER want to hook up an electrolytic capacitor backwards as they tend to pop quite loudly and fling metal foil everywhere like a party popper / chaff canister. Scary if you don't know they do that.
Fixing something that was deemed unfixable by someone else is one of the best things in the world, and that probably got you at least one dedicated customer that’s going to sing your praises to everyone.

Well there you go.. Don't trust the last guy, because they couldn't fix it.. Even if its you. So many times, people are told what the problem is, or what the last guy has tried, and they get blinded and don't check and verify if they diagnosis was right, so they never find the problem.. So bravo to you, and your ability to step back to square one, and to ignore what the "expert" said.. cause if you didn't, it be in the spare parts pile.

Successfully going to the edge and beyond your own knowledge always feels very good and strengthens your self-confidence. But what really bothers me, and that seems to me to be a symptom of our time, is the inability or deliberate refusal of the specialist workshop to correctly localize and fix the fault. It is all the more good to know that there are still gifted technicians, mechanics and craftsmen out there to stand up to this symptom. The difficulty of our time is to find these people. I think one of these people has impressively manifested himself here. This is my first comment on one of your videos. YT noticed me to your channel just a few days ago and I've started devouring the uploaded videos from the past few years. Nice greetings from Germany.
In my very limited schooling in electronics I was never told about the limited life of electrolytic capacitors. It cost a few bucks to learn that lesson as I got into vintage car and home audio. Needless to say, recapping my second amplifier cured me of that hobby.
Not necessarily always (when new) but chances are in 20+ years electrolytic caps are the first to go after. Yes, been there, done that in old oscilloscopes. Edit: Should have qualified - high-value aluminum electrolytic caps (Tek scopes, anyway)
hear hear! I was diagnosing a dead IBM PS/2 Model 80 last night, and it's of course bad caps! and not the tantalums on the motherboard as I've replaced those already. it was sneakily hidden, very high ESR electrolytic caps on the floppy drive.
@@milantrcka121 it's highly dependent on operating conditions I think. Here in the UK we have reasonable temperature swing (generally -10c to +30c at the very worst, more usually around 0c to 25c) and old electrolytics are quite often in better shape than a cheaper new item in terms of ESR. Also electrolyte composition can be a problem (infamous '90s leakers) but in general it's been anything but caps in most of my repairs. (example being my Philips PM3200X 'scope, every single electrolytic tested good and was reinstalled, the problems were entirely down to dirty switches and lockfit transistors)
To be fair, I've found this to be far less of an issue in industrial equipment than junk consumer products. They tend to use good quality components that are overbuilt. I've worked on 50 years old electronics that were all original.
Nice fix Wes. When I had an electronics repair shop people would bring me some crazy stuff to see if I could repair it because of an overstated reputation for being able to fix almost anything and I was their last resort. You obviously have that reputation in your community, not to mention UA-cam. Your skills are amazing. I did my best.
I run into electronic stuff I can't repair all the time. Especially at the board level. There are never any schematics so it's just a guessing game. As things get smaller and go to all surface mount I'm basically unable to even try.
@@WatchWesWork I feel your pain about surface mount technology as it pretty much ended that business. Almost never had schematics and used a lot of different equipment to troubleshoot but the Huntron tracker was my go to for quick diagnosis and even better if you had a known good board to compare with. Most everything is replace the entire board now unless it's a component that isn't surface mount or a cold solder connection.
Your best diagnostic talent is that you don't quit. There is a problem, keep looking until you find the cause. Great job eliminating potentials until the culprit is found. Thanks for sharing.
Congratulations Wes for getting very close too 100,000 subs. " YOU & YOUR WIFE DESERVE IT ". You will be there in no time for sure. " YOU'RE A CELEBRITY BRO ".
Hi guy - 30 year generator guy here. A very easy way to test for shorted windings in main power windings is to check for what is called residual voltage. All generators, as you know, work by controlling the strength of the magnetic field for whatever stator your working with - the interesting thing about a welder is you have a couple of generators and two separate fields in the same machine. So you have two separate systems for voltage regulation - also there is what is called the field flashing circuit. That is the circuit that feeds battery voltage directly from the battery to the winding that needs to be flashed to get the generator magnetism built up so it can be self powering. Now the reason they have these field flashing circuits is that on a welder they might sit for a year or more between uses - in that period of time the "residual magnetism" might dissipate to a point that the electrical voltage created by the residual magnetism might not be enough to allow the cascade effect [the ability for the generator to start building its voltage from it's own power] to get the generator to reach its required voltage. Now for the easy test - if there are no shorts in the power side of the generator with all the regulation inputs removed [just pull the brushes on a welder] bring the machine to rated speed and check for residual voltage - on a 240 volt system the residual will be much less than the 240 but it must be equal on each leg to ground - on a welder like you had just check the residual at the input to the 3 phase rectifier - be sure a disconnect the welder from the rectifier so that you can isolate the generator from any failed components in the rectifier... if all the residual voltages are balanced then your problem is not with any of the main components of the generator. The residual voltage has no real power so if something is shorted the residual will be pulled down or not balanced- kind of like the 5 volt reference on a car. If you find a problem here this is where you break out the megger .. now I can tell you a megger can let lots of smoke out of the controls of a welder - the multimeter will apply 9 volts to the coil and look for shorts - if you put a megger on a generator to test it you better make sure you disconnect every sensing wire of every kind that leads to any electronics board - that board is not gonna like the voltage from the megger - 250 volts is the lowest voltage I know of that u can buy - I have one that is 250 - 500 and 1000 volts - the only thing you should be testing with a megger is insulation leakage. Just be very careful with one... most power generator systems are simple and consist of 3 main systems - regulation - power and retification in the case of a welder - so split the systems and see what dont work. For fast diagnosis just get one of those small recitifers an hook up the ac side of it to a veriack and the DC side to whatever excitation coil system u want to check - fire the generator up and raise the voltage on the veriack till you get either the weld voltage or ac voltage [whichever system ur checking]. If you get good response from this test go straight to the regulation system. So guy you did good fixing those welders. I like your videos ... I'm 70 years old now and just piddle with different mechanical things and a few welders.. they keep me from making a fool out of myself chasing women... keep up the fun videos.
Nice job Wes.....You got it working when everyone at miller would have junked it. I love taking someone's broken beyond repair equipment and fixing it and using it for 3 to 5 more years.
For a guy who doesn't know much about electronics and such, you sure know a lot :) I'm impressed you were able to diagnose that bad cap! Just a note: many handheld meters have an upper limit of their ability to measure capacitance, so just because it reads OL, doesn't mean the cap is bad, you just may be exceeding its measuring capacity. In this case, your meter tops out at 1000µF, and that cap's rated 1200 +50% -20% (960-1800), so there's a 95% chance that even if the cap was good it would have read OL. That said, good on you for following up with a resistance check. A good cap should start out with a low resistance than trend upwards as it charges. Keep up the great videos, I really enjoy them, and always look forwards to your next videos.
Hi Wes, hey pal, don't kid yourself. You are getting a good handle on the electric side of things just fine. I've been at this for 50 yrs, I'm still learning. The only screaming at the screen happened at .1 Ω ...it's DEAD, bereft of farads, just a short across the raw DC! Replace it immediately!! Otherwise, thoughtful approach & nicely done!
A very modest summary at the end. Speaking as an electronics engineer, I think you did a great job of logically tracking down the fault and I'm sure it'll be 100%. Says a lot about the "authorised service centre". As for the Lincoln control panel, that's just ridiculous - not only the fiddly controls, but an lcd screen in a welding environment isn't going to survive long (as demonstrated by the big scratch already). Probably driven by a promise of cost savings on separate switches.
Thank you wes I am truly serious you are the master of the diagnostics of welders or cars if I lived anywhere close you be the only mechanic I would ever use thank you for the videos and God bless you and your family can't wait til next and when merch comes back I would be proud to wear it
Nice, a Watch Wes Work video during the middle of the week! More of these would be very much appreciated, but I understand you only have so much time. Also a shoutout to all of the veterans on Veteran's Day. Thank you for all you do!
Best gas welder video repair I’ve seen, my Lincoln Weldanpower 150AC now gets its excitation from two D cell batteries because the exciter coil behind the flywheel is dead and not available. Must have diode between rotor brushes and batteries because back EMF from the once activated rotor could explode the D cells.
Good troubleshoot and repair Wes! Couple thoughts on the capacitor: If you don't have a meter that tests for capacitance, you can test a cap with an Ohmmeter, good indication when testing caps is your resistance will go up as you test, (be sure to observe polarity on dc marked caps) the voltage from your meter actually charges the capacitor, a fully discharged cap will read near short, and as it nears equilibrium to your meters test voltage, it will go to open. Near short or high resistance in a cap is not necessarily bad, as long as you can see the change as the cap charges up. If you want to recreate, short out the cap and repeat, it will start low and go high resistance again. The old analog Simpson type meters were really nice for this, you would have the needle sweep near short and then sweep back towards open. Second thought is any kind of physical deformation or discoloration usually means dead cap, Ive never seen one with multiple dents like that, swollen, leaking, cracked, charred, sure, but that one almost looked like someone hit it with a ball peen hammer.
Your channel is really cool. Your way explaining things is entertaining and informative at the same time. Please continue making this great stuff. Congratulations on nearly reaching 100k subscribers.
good job saving a perfectly usable machine Wes. there's nothing i like better than to see an older machine put back into service with a few parts and repairs.
Wes, I love your persistence in trying to figure out the problem. I myself would have given up but because you are who you are the client should be extremely satisfied. You are a blessed man having that kind of drive. Love the videos. I'll be watching.
Good things come to good people, so great to see that PJ gave you the taps! Thanks Wes, for another interesting and well explained video. Regards from the UK.
I have started helping save 80s & 90s equipment at an industrial printer & your method is spot on. Filter caps should always be suspects once equipment is past 20 years. I saved a huge printing press by replacing $12 of capacitors.
I love when you walk through schematics with us. I'm an electrician by trade and honestly still learn things along the way. Especially on cars and can bus. Thank you and please keep it up.
Awesome work Wes, I had a Lincoln Ranger 9 that wouldn’t ever rev up when loaded and I fooled with it for more time than I should have it needed a pc board that was no longer available and I ended up selling it off, I’m a lift truck mechanic by trade and watching you work makes me proud to know there’s still some true diagnosticians out there. I completely understand that feeling of accomplishment that comes with completing a repair that is at the edge of your abilities or just beyond, in a weird way that’s what keep me going sometimes
Nice work and your commitment to fixing it is terrific. I've had shops give up and tell me something cannot be repaired or replaced. By tinkering around and talking with older mechanics and truck drivers, I repaired the problem.
Awesome channel and great info. I'm inclined on most things mechanical, but not much on electrical repairs. Heck wiring diagrams used to intimidate me quite a bit. But after watching your videos like this I've learned alot on how to understand them and test circuits. Thanks Wes!
Great repairs Wes! I work in a power plant with much bigger generators (390 MW) your explanation of fields and excitation is pretty much spot on. Hope you get to your 100K subscribers, I eagerly await your programmes each week. 🇦🇺
Wes , You just saved that guy a butt load of money ! I grew up in Illinois, Granddad owned Guaranteed Gear Service into the fifties . You have the same "I can fix it " attitude that he instilled In me . My father had a TV and radio repair shop ,he taught me a lot about reading schematics. What you just did, quantified your abilities. No more hiding behind your Clark Kent persona . When you hit your 100K subs , I'm going to expose you for the real Superman you are . Much love my brother. You keep it real !
Love this, thanks for making it. I subscribed to your channel when you were buying and fixing CNC machines - I loved the diversity and watching you reverse engineer 1000 year old circuit boards. I totally get it that the mechanic work gets a bit more traction than that did (and I enjoy watching for your approach and personality despite not caring too much about mechanics), but it's nice to see you flex your other skills on video again.
Absolutely spot on. When you take the chance to push your ability slightly further with success is the best. Congratulations, you already have superior skill and when I see you learn something new is very satisfying and encourages me to push myself as well.
Hi Wes! Great vidga. Logger wade reference! I followed your wire diagram explanation, I'm not a electrician. I am however a RV service tech of 29 years, I know enough to get by. My dad owns a metal manufacturing company, Ag industry we have welders from Miller that are OLD. Like 39 years old. Have had the miller company try to buy them back from us. We tell them NO Not Happening. They still work and we will run them into the ground 😂. Less moving parts less wear and tear. They're always trying to sell us new machines and we don't want them. Ps how did your wife find such a smart guy? Does she know how lucky she is? Lol keep up the great Vidgas.
I can't even begin to count how many times I've went to repair an electronic device and the very first thing I do is reset every connector on the machine I'm repairing and sure enough it began working. Especially anything made to be portable. I always spray, drip or wipe all connectors with an anti corrosion product Deoxit. They have a low and high temp version that comes in spray, wipes and drip bottle. It's expensive but worth every penny in saved service calls. I've used it on boats, arcade and pinball games, jukeboxes, cars and motorcycles since I first had it recommended to me by a friend who repairs computers back when I lived in the Florida Keys and was the Service Manager for the local Amusement Vending company down there. It saved me a whole lotta service calls.
Over the years I have found that it is always a good idea to look for signs of damaged capacitors. Congratulations on almost 100K subs. I am still hoping for 100 one day.
Had a 35A 12v power supply that kept dropping voltage under load. popped the cover. Checked the capacitors 2 48,000 uF caps. One was just like that one. Dead. Read nothing on the meter. Other was fine. Replaced working good as new. Electrolytes go bad a lot when they get age on them. The electrolyte dries out over time. Great job!
As an Electrical Engineer, I can say your debugging skills are right on track. Great job. Electrolytic caps have known aging issues, and do need to be replaced from time to time in older equipment. Given the welder is 25 years old, it is getting to that age where some of the caps will start to go bad. You definitely NEVER want to hook up an electrolytic capacitor backwards as they tend to pop quite loudly and fling metal foil everywhere like a party popper / chaff canister. Scary if you don't know they do that.

Second thought is any kind of physical deformation or discoloration usually means dead cap, Ive never seen one with multiple dents like that, swollen, leaking, cracked, charred, sure, but that one almost looked like someone hit it with a ball peen hammer.
I have an ESR meter that works well for testing caps. It's definitely a dead short.
Well done Wes, you continue to amaze me.
You didn’t say if Mrs Wes was fussing over you like a mother hen cause you had a cold..
Love watching you diagnose wiring stuff!
The Florida pool pump motor repair guy approved ! Wes that was good info
Almost 100k, a great achievement especially because you keep it so real. Keep it up!
just found your channel a few months ago, really enjoy it wes, thanks for taking the time to share you knowledge and experience with us
I love your process, and I admire your tenacity, there aren't many 'younger' mechanics out there that do what you do. Congrats man.
100k is well deserved. See you at 250k
You’re good at what you do and anything you do. Job well done 👍
Congratulations on approaching your 100,000 subscribers well deserved Wes. 🏁🏁🏁
Your channel is really cool. Your way explaining things is entertaining and informative at the same time. Please continue making this great stuff. Congratulations on nearly reaching 100k subscribers.
Great job and a great high road approach to letting the other shop off the hook. Well played, sir! 👍🏻
This was on the edge of my ability just to follow! (Which is also very satisfying.)
Well done on 100k. I think I've been here since about 20k and your content is top notch.
good job saving a perfectly usable machine Wes. there's nothing i like better than to see an older machine put back into service with a few parts and repairs.
You did it again, became a certified electric welder whisperer! Nice job on the diagnostics! 😊
Wes, That is definitely a double win!! Excellent troubleshooting skills!
Love your electronics troubleshooting videos!
Wes, I love your persistence in trying to figure out the problem. I myself would have given up but because you are who you are the client should be extremely satisfied. You are a blessed man having that kind of drive. Love the videos. I'll be watching.
Congratulations are reaching this milestone Wes!!!
Well done Wes. Your really sharp.
You a a real thinker Wes. Brilliant!
Well done work, Wes.
Good things come to good people, so great to see that PJ gave you the taps! Thanks Wes, for another interesting and well explained video. Regards from the UK.
I have started helping save 80s & 90s equipment at an industrial printer & your method is spot on. Filter caps should always be suspects once equipment is past 20 years. I saved a huge printing press by replacing $12 of capacitors.
Well done on the troubleshooting.
I love when you walk through schematics with us. I'm an electrician by trade and honestly still learn things along the way. Especially on cars and can bus. Thank you and please keep it up.
Always good to see your videos!!! Every time I learn something new with you. Thanks man
Awesome work Wes, I had a Lincoln Ranger 9 that wouldn’t ever rev up when loaded and I fooled with it for more time than I should have it needed a pc board that was no longer available and I ended up selling it off, I’m a lift truck mechanic by trade and watching you work makes me proud to know there’s still some true diagnosticians out there. I completely understand that feeling of accomplishment that comes with completing a repair that is at the edge of your abilities or just beyond, in a weird way that’s what keep me going sometimes
That big filter cap was puffed up like a ball park frank! I’d say it got very hot. Good fix.
Nice work and your commitment to fixing it is terrific. I've had shops give up and tell me something cannot be repaired or replaced. By tinkering around and talking with older mechanics and truck drivers, I repaired the problem.
It's been great watching your channel grow. Congratulations on your UA-cam success.
Thank you so much!
Fantastic analysis and use of common sense!
Just watched this. As a retired Marine Electrician, I I AM impressed ! Great troubleshooting !
Man you are good thats why l like to watch wes work thank you sir keep it up cheers from Jacksonville Florida
Excellent work! It’ll probably work forever! Keep it up!
Awesome channel and great info. I'm inclined on most things mechanical, but not much on electrical repairs. Heck wiring diagrams used to intimidate me quite a bit. But after watching your videos like this I've learned alot on how to understand them and test circuits. Thanks Wes!
Wes. You are one smart dude!! Congratulations!
NIce job Wes , congratulations on the 100 K , I'm sure the owner of that welder is a new lifetime customer .
Dang Wes you continually amaze me with your abilities , you one smart fella 👌.
Great repairs Wes! I work in a power plant with much bigger generators (390 MW) your explanation of fields and excitation is pretty much spot on. Hope you get to your 100K subscribers, I eagerly await your programmes each week. 🇦🇺
I grew up in a logging company and your video brings me back to does days with my dad and does big machines.. kudos from the Philippines!
You are brilliant Wes 👍
Wes, I wish I had your diagnostic skills to solve complicated problems like that. Good Luck on you 100K membership goal, you will make it.
Wes , You just saved that guy a butt load of money ! I grew up in Illinois, Granddad owned Guaranteed Gear Service into the fifties . You have the same "I can fix it " attitude that he instilled In me . My father had a TV and radio repair shop ,he taught me a lot about reading schematics.
What you just did, quantified your abilities. No more hiding behind your Clark Kent persona . When you hit your 100K subs , I'm going to expose you for the real Superman you are . Much love my brother. You keep it real !
awesome job PJ!
Thank god you have common sense and patience Wes enjoyed watching you work this out well done mate 👍👍👍
you have great communication skills. Another success story!
I'm inspired to push my limits on understanding circuitry due to your videos. Thanks for putting this content out there.
Very interesting to watch video. I've only got smaller everlast inverter welders so watching someone work with an engine welder is pretty cool.
Love this, thanks for making it. I subscribed to your channel when you were buying and fixing CNC machines - I loved the diversity and watching you reverse engineer 1000 year old circuit boards. I totally get it that the mechanic work gets a bit more traction than that did (and I enjoy watching for your approach and personality despite not caring too much about mechanics), but it's nice to see you flex your other skills on video again.
Great job Wes
Absolutely spot on. When you take the chance to push your ability slightly further with success is the best. Congratulations, you already have superior skill and when I see you learn something new is very satisfying and encourages me to push myself as well.
Hi Wes! Great vidga. Logger wade reference! I followed your wire diagram explanation, I'm not a electrician. I am however a RV service tech of 29 years, I know enough to get by. My dad owns a metal manufacturing company, Ag industry we have welders from Miller that are OLD. Like 39 years old. Have had the miller company try to buy them back from us. We tell them NO Not Happening. They still work and we will run them into the ground 😂. Less moving parts less wear and tear. They're always trying to sell us new machines and we don't want them. Ps how did your wife find such a smart guy? Does she know how lucky she is? Lol keep up the great Vidgas.
I can't even begin to count how many times I've went to repair an electronic device and the very first thing I do is reset every connector on the machine I'm repairing and sure enough it began working.
Especially anything made to be portable.
I always spray, drip or wipe all connectors with an anti corrosion product Deoxit.
They have a low and high temp version that comes in spray, wipes and drip bottle.
It's expensive but worth every penny in saved service calls.
I've used it on boats, arcade and pinball games, jukeboxes, cars and motorcycles since I first had it recommended to me by a friend who repairs computers back when I lived in the Florida Keys and was the Service Manager for the local Amusement Vending company down there.
It saved me a whole lotta service calls.
Wow, that was real nice of P.J. Seems like you good fellas find each other even when you're not trying.
You are very modest and one smart cookie
Over the years I have found that it is always a good idea to look for signs of damaged capacitors. Congratulations on almost 100K subs.
I am still hoping for 100 one day.
You'll get there!
Just subbed :) 57 now. I like the pocket balance resto you did.
@@ragfour9303 thank you. You are very kind
Great video Wes, nice work!
Had a 35A 12v power supply that kept dropping voltage under load. popped the cover. Checked the capacitors 2 48,000 uF caps. One was just like that one. Dead. Read nothing on the meter. Other was fine. Replaced working good as new. Electrolytes go bad a lot when they get age on them. The electrolyte dries out over time. Great job!
Absolutely fantastic 🤩 Wes 👍🏻🏴
