2/3 of your heat is always on the neg side - you have it backwards. That's why you get more penetration on the EP as opposed to a shallow weld on the EN side
Hello again , I noticed in other videos explaining the difference in polarity it is also mentioned that DCEN polarity provides deeper penetration and DCEP is preferred for welding thinner material . Thanks
Yes. I don't know which explanation is the correct. DCEP or DCEN is best for thin metals? Arguments are opposite depending on the source you consult and both seems to be the correct one
Such a good video, was confused on a few things especially when it comes to polarity. Thank you. Also for anyone wondering his course is totally worth it[60$ i think] just recently finished the stick welding as thats what i'm learning on. will promptly get to the mig and tig courses as time and fund permits.
You should study how the elections leave and go to the plate for straight (en) and reverse (ep). I'll give you a hint, it has to do with electron concentration.
The easiest way i found to explain this, is this: with DCEP (reverse polarity) 70% percent of the heat is at the electrode and 30% of the heat is at the work, DCEN (straight polarity) 70% of the heat is at the work (ground cable side) and only 30% is at the electrode side. I have primarily only welded with DCEP when using SMAW. However this is a great benefit while using Tig, allowing you to put maximum amount of heat into your work while saving your tungsten from exploding
This video gives the best explanations I remember hearing on he subjects covered. It cleared up some things I didn't understand. You also stated your qualiications and unlike some content providers, you appeared to be stone cold sober. Thank you very much.
Great stuff Tim, DCEN along with less penetration, has more build up too, helpful for jumping big gaps on think material. AC has more buildup than DCEP but less than DCEN and has less penetration than DCEP. Big electrodes over 5/32 run better on AC and when your leads are long, [ over 100 feet?] AC is the better way to go, but AC is more dangerous in confined space or damp areas...... Your video is very informative, thanks for making and sharing, cheers form Florida, Paul p.s. AC 7018 rods run on all polarity and relight easy compared to regular 7018....not sure why, but they do not get the hard slag on tip that needs removing before a restrict. great for confined areas where restriking is a problem
Thankyou soo much for these videos, im a beginner who wanted to learn welding but was too afraid and had no idea about welding, but after watching your videos and practicing , i feel like i know welding for a long time and im loving this. thanks again and cant wait to learn more from you.
Let me give you a hint to everyone questioning real life examples. You will be mostly running DCEN (earth cable will be +) because let's face it, you will be doing rust repair which is why you bought that IGBT inverter welder. Stuff that is thin, stuff that you have 1 shot at doing right, stuff you want to tack in place like a washer and a nut etc...basically you don't want to end up blowing holes. Another good thing about DCEN is there is less splatter as you probably noticed in the videos which is why 10 years ago everybody in the forums was telling you to run DCEN on inverter welder. Now if you want to weld a differential for drifting or something structural with lots of meat, sure turn back DCEP + to + and - to - Short version: when it comes to stick welding, penetration is never going to be a problem.
What dimension of material is considered "something thin"? I plan to weld together the new tailpipe onto my existing exhaust system pipe exiting the muffler on my 2002 Chevy 3500. T he orig exhaust system is welded, not clamped. I'm a beginner, just bought a buzz box, I'm setting up a 50A DP circuit for it. Seller gave me a few hundred various rods. Thanks for your clear explanation. I've subscribed to your channel.
I had an old lincoln that I got rid of because I was moving and didn't feel like taking it. 😒 Mistake but it was great, it would run ac or dc with just a flip of a switch.
I've read multiple books, and watched hours about arc welding and it seems no one can explain polarity correctly. If in DCEP heat is less on the work piece then how it melts deeper and ⅔ of heat is on electrode so why it melts slower. Nothing makes sense.
Sorry, forgot to add at the end of my last comment. Nice job, you're a good teacher. I hope you keep making videos. I wish I had a resource like this when I was first starting out
Just welded up a 1.3 exhaust with DC neg yesterday, use the positive and it will go through like butter I think your under cut was probably caused by running the neg one slower trying to compensate for the lighter burn
Great video. It really put these into perspective. I have an AC welder but it's one of the Chinese models that apparently is supposed to be arc, mig, tig and plasma cutter AIO and even though I did read the manual there was a lot to take in so I'm now curious to know if it can do both AC and DC with just a switch of the cables on the ports. Thanks 👍
hi thanks for the great video . Im confused on the penetration issue. most of what I have read from welding books I bought over the years say that DCEN gives better penetration since more heat is at the base metal . Is that old theory and has it changed ? Thanks
Hi, I had not heard of it some years ago . And we had to weld stainless steel square 2mm tubing. we did the job, but it was difficult enough. Now, lately, I have heard that welding with the negative side is better it does not penetrate so deep, and the electrode melts a bit vaster . I tried it out and oh boy if we had known that it is so much easier . Ireland
I am wondering how you got deeper penetration with DCEP and less with DCEN when with DCEP approximately 2/3 of the heat goes to to rod and 1/3 to the work and with DCEN approximately 1/3 of the heat goes to to rod and 2/3 to the work?
I just found your channel yesterday and have been binge watching ever since. As a newbie to welding, I find your videos very helpful. This is not a criticism but your audio sounds as if your in a bit of a bowl or echo chamber and comes across a bit "tinny and hollow" if that makes any sense. Regardless, I will be watching all of your past and future videos!
Awesome! Thanks. I find that with dcen i can maintain an arc with less amperage than with dcep. Also with dcen the arc blows/pushes the slag out of the way more effectively than dcep, i can get the slag to peel, using 6011 or 6010 with dcen.
Correct. He’s a good welder but he’s really got this wrong here in this video for understanding. You should always start with DCEN first unless your doing very thin material.
Mmmm I am going to try DCEN for thin square tubing... I wish I could afford a mig, but here where I live it's super expensive to have a mig or tig for occasional use, unless you have welding shop which I dont
Hi, great video. I *think* the choice of dcep or dcen is also depends on your chosen electrode. The electrode manufacturer indicates wether it's a dcep or dcen, wouldn't you go by what they say?
Doesn't that just mean we'd choose our rod accordingly? Seems a lot of those polarity call-outs are for AC and one of the DCs. btw, this video could help me redo my last project .. after I grind out the globs I left on the entire first attempt, lol. I was running 1/8" 7014 at ~120a but AC because I didn't know better. :-/
every time I weld, I burn through the metal. I'm running 60 amps with 1/8 inch 6013. my travel is the same as yours, but I'm falling through. I have a deko 160. maybe my welder sucks? it seems like a box of lightning. I've never run it past 60 amps. I figure if I'm burning through, I don't need any more, right?
The reverse / straight polarity terminology always drove me nuts. Especially since the vast majority of DC systems are negative ground - so it's backwards from the stupid old school non-descriptive welding terminology. There is NO mistaking what DC electrode negative means. But it gets even worse than reverse/straight ... I've seen "DC+" and "DC-" used to indicate ... "DC+ = work piece is positive" ... WHAT??? What good is specifying a polarity, then not specifying which of the 2 is positive - and why if you do that, would you go against convention of "DCEN" where you're talking about the electrode, not the work clamp? All the "bubba science" in welding man ... it's one reason I gave up on it 20 years ago. Met a lot of super high skilled welders that either didn't know - or couldn't explain to anybody that didn't already know. Or it was protectionism, which is equally stupid. Some guys you ask how to do X, and the answer is "you just gotta know how to do it" or some asinine nonsense.
Good morning, Tim, I need ur input am using a ARC -200 mini welding plant. I need to know the types rods to us on it. I have been using J422 rod and 6013 rods but am getting a lot of flocks????????
Great video! Maybe you can help me. I’m trying to run a Lincoln buzz box AC welder on a 10,000/8,000 running watt generator. It has a 50amp output. The highest amperage setting I can run it at is at 75 amps. At 90 and above it trips the breaker on the generator. When I check the amperage at the welder’s cord I’m pulling 45 amp on each leg, that’s welding at 75 amps. At. 90A it goes to 55A per leg, thus tripping the breaker on the generator. After watching this video, I’m wondering if I convert it to run at DCEP or DCEN, if possible. Do know if the amperage at the cord/plug/panel would be reduced to lower amperages? After looking into my issues, I’m thinking I may have try an Inverter welder of some sort. Thanks in advance for any help
I can't see the "penetration" you are talking about. Perhaps you need to look at it under a microscope for the viewer to see the difference between the surfaces due to etching. I do agree that the term "reverse polarity" is not informative. "Reverse of what?" I would ask. "Reverse of Normal" is not informative. Before it means anything you need to know what is normal and why it is normal. It might be just as logical to call the reverse as being normal. I think a better term would be Cathode vs Anode Welding. Those two terms are crystal clear if you know what they mean.
Hello Is it allowed on build in cables to modefie them to a connector typ cable plug in system on arc Stick welder? My old cable and holder is probably broken and corroded and I was wondering if I could replace the hole thing with a changeable version. 🤔
Only critique is for me being a novice watching to understand the 3 and the difference, it would had been more helpful if you’d experienced welding on the thin metal. The flip side, thank you for your no BS approach and putting that disclaimer on and being open and honest. Thank you
I saw a commenter that said EP, means earth positive, so (electrode negative) I heard there is less a player with E N. Electrode negative, but it is harder to not, stick welds, smaller ham maintenance required? Is any of this relevant?
6013 is my favourite rod, id love to see some videos of fillet welds with different rods, when i was learning stick sometimes i felt i got good penetration until i cut it on the bandsaw and could clearly see the parent metal zero fusion, mad respect to all the welders of all diciplines, metallurgy is facinating
Maybe unpainful to remember now.. Electrode positive is for deeper melt-penetration. Electrode negative is for surface melting thinner material. Before now I had to remember negative rich electrons discharged onto positive conductors, similar to radiation leaked heat onto molecules slower or inactive. Star solar source plus planet geology motions even within botany does constantly gravity-pathway such. It is all relative probably is expression snaring me regardless of never entering a physics class. Some rumor said battery industry began intentionally mislabeled posts to relieve their headache. Curiosity about welding a ceiling perhaps adequately distracts aesthetically. My mental health is best served by forgetting all that and similar confusers in preference for relearning each refreshed. Yes absolutely dceP means Penetrator. Bye bye
One big reason to use DC (instead of AC) is to avoid electrocuting yourself while repairing that dang piece of equipment while standing in the rain, sleet and mud!
Your video fills the gap between explanation and practical result which in my amateur experimentation is that DCEN produces less holes on thin material!
So what does that mean on a machine that has it listed as dcrp and dcsp I know it stands for DC reverse polarity and DC straight polarity but having a hard time finding information on these old terms versus the new ones aside from the little bit you went over in the beginning which basically means that dcrp is basically having it set at positive polarity so I am assuming dcsp is negative polarity? I'm a little confused but get the general gist of it
Generally, I’ve used those terms relating more to short circuit MIG welding where the arc is not continuous. With stick welding, the arc is always on so those don’t apply as much unless you’re whipping and then that would be controlled with a dig or arc force setting if you had one. Polarity will really just affect penetration with stick welding and DCEP is almost always the better option.
Thanks! Naval jelly is a great option because it's available at the hardware store. I've found the nital that I used works better, though I was also disappointed with how it showed up on camera in this one.
You can learn to weld. I'll show you exactly what to do in my affordable online welding courses at courses.timwelds.com.
Are there special precautions to be taken when doing DCEN? Any risks of electrocution compared to DCEP?
2/3 of your heat is always on the neg side - you have it backwards. That's why you get more penetration on the EP as opposed to a shallow weld on the EN side
Hi,
What does IGBT stand for? Is that a DC welder?
As a hobby welder, excellent info, thanks!
Glad it was helpful!

Yes. I don't know which explanation is the correct. DCEP or DCEN is best for thin metals? Arguments are opposite depending on the source you consult and both seems to be the correct one
You got it all mixed up sir
Such a good video, was confused on a few things especially when it comes to polarity. Thank you. Also for anyone wondering his course is totally worth it[60$ i think] just recently finished the stick welding as thats what i'm learning on. will promptly get to the mig and tig courses as time and fund permits.
Thank you! I appreciate it!
A welding engineer, I wish I knew about that when I was in college. I like welding better than my current job. Keep up the good work.👍
Thanks for explaining this Tim! What is the polisher with the yellow holder?
Excellent! Direct and to the point !!!
Great video, thank you.
Thanks Tim and heck yeah it helped like all your vids!
You should study how the elections leave and go to the plate for straight (en) and reverse (ep). I'll give you a hint, it has to do with electron concentration.
Wish you had showed the the electrode connection better
The easiest way i found to explain this, is this: with DCEP (reverse polarity) 70% percent of the heat is at the electrode and 30% of the heat is at the work, DCEN (straight polarity) 70% of the heat is at the work (ground cable side) and only 30% is at the electrode side.
I have primarily only welded with DCEP when using SMAW. However this is a great benefit while using Tig, allowing you to put maximum amount of heat into your work while saving your tungsten from exploding
I think DCEN (straight polarity) has deeper penetration ,since heat distribution on the work metal is higher and which melt faster than DCEP.
This really helps! Been having trouble with welding metals almost as thin as a razor blade lately but not anymore thanks to you, sir!
This video gives the best explanations I remember hearing on he subjects covered. It cleared up some things I didn't understand.

Always good to learn from you Tim. Thanks for sharing
Best welding channel on UA-cam! I used to watch that ChuckE2009 before he lost his f¤%&ing mind. Tim is on another level. I salute you, Sir!
I used to like that channel as well, and left for the same reason.
Wat happened to him?
I love this guy too. he’s very informative, clearly explains the topic in a way a total newcomer can understand and gets to the point
I had an old lincoln that I got rid of because I was moving and didn't feel like taking it. 😒 Mistake but it was great, it would run ac or dc with just a flip of a switch.
I’m just starting welding school and man I am so grateful to have all these wonderful videos to help me out. Thank you.

Hey Tim, appreciate you sharing your knowledge . . . just purchased a Mig/Stick machine . . . hope to fire it up and apply your tips . . . thanks!
Great video….no swearing and no, “ I’m the best welder in the universe”. Just good information delivered in a matter of fact way …thank you.
Sorry, forgot to add at the end of my last comment. Nice job, you're a good teacher. I hope you keep making videos.

Does the Amperage setting change when selecting between the DCEP/DCEN/AC?
hi thanks for the great video . Im confused on the penetration issue. most of what I have read from welding books I bought over the years say that DCEN gives better penetration since more heat is at the base metal . Is that old theory and has it changed ? Thanks
As always, your videos are always concise and straightforward with the added value of cutting and etching to show the results!!! Thank you!
Greatly appreciated. You keep your explanations nicely tempered in meat and gravy, just perfect for any noob
ok ..then i need to reverse my polarity cause my e6011 rods keep sticking and wont weld but my 6013s do just fine.
Hi, I had not heard of it some years ago . And we had to weld stainless steel square 2mm tubing. we did the job, but it was difficult enough. Now, lately, I have heard that welding with the negative side is better it does not penetrate so deep, and the electrode melts a bit vaster .

I still dnt understand. Heat at work? Heat in the electrodes??? Explain the stuff while using examples.
I am wondering how you got deeper penetration with DCEP and less with DCEN when with DCEP approximately 2/3 of the heat goes to to rod and 1/3 to the work and with DCEN approximately 1/3 of the heat goes to to rod and 2/3 to the work?
Correct. He’s confused on this point for some reason. He’s a good teacher otherwise, just don’t think this is particularly solid advice.
Very useful information..
Thanks,, from a complete newbie..👍

Correct. He’s a good welder but he’s really got this wrong here in this video for understanding. You should always start with DCEN first unless your doing very thin material.
why cant you test on thin ,thats when we switch polarity .. DCEP is for thin but arc lost , too much slug build up .. what to do?
Hi,de normal recomandation pozition DCEP is for all electrods 6013,7018 etc?
I love ur teaching you explain so clear to understand I watch most of your videos.
Mmmm I am going to try DCEN for thin square tubing... I wish I could afford a mig, but here where I live it's super expensive to have a mig or tig for occasional use, unless you have welding shop which I dont
Get yourself the tig torch that Tim recommends you can run a tig rig from your DC stick welder
Зачем такой долгий гундёж?просто нельзя сказать куда пожключать провода?
i accidentally switched the polarity on my welder and it started smoking
You can use Easy Off oven cleaner. It’s the only thing I use it for.
Really appreciate your easy to understand explanation of welding concepts. Thank you.
Thanks so much for your in depth and very informative videos!
thank you for this. just set up my tig/stick power source today
Thanx bud
Nice explanation and very useful. Many thanks.
Excellent explanation, Question how do you know which machines can switch between DCEP or DCEN ?
Any DC stick machine can be switched, though it will be easier if there is a polarity switch or removable leads which can be reversed.
Hi, great video. I *think* the choice of dcep or dcen is also depends on your chosen electrode. The electrode manufacturer indicates wether it's a dcep or dcen, wouldn't you go by what they say?
Doesn't that just mean we'd choose our rod accordingly? Seems a lot of those polarity call-outs are for AC and one of the DCs. btw, this video could help me redo my last project .. after I grind out the globs I left on the entire first attempt, lol. I was running 1/8" 7014 at ~120a but AC because I didn't know better. :-/
ac is not dc reversing polarity, it is a sine wave.
THANKS BROTHER FOR THE AWESOME VIDEO!!!!!!!
every time I weld, I burn through the metal. I'm running 60 amps with 1/8 inch 6013. my travel is the same as yours, but I'm falling through. I have a deko 160. maybe my welder sucks? it seems like a box of lightning. I've never run it past 60 amps. I figure if I'm burning through, I don't need any more, right?

Very informative,for a buzz box is the electrode positive or negative?
A buzz box, like the one in the video, the Lincoln 225 is AC. It "buzzes" because it is AC.
Great videos thanks for sharing.
Hi, I have an inverter MMA 315A welder (DIY) is it still possible to change from the + / - on an inverter type welder ???
thanks
Good morning, Tim, I need ur input am using a ARC -200 mini welding plant. I need to know the types rods to us on it. I have been using J422 rod and 6013 rods but am getting a lot of flocks????????

Dear anyone.
I felt that DCEN is deeper penetration. DCEP is shallow type.
By mistakenly he interchanged.
Am i correct
I'm just here to say thanks! I have a few things to fix around my home, now I think I can get started.

Hello
Is it allowed on build in cables to modefie them to a connector typ cable plug in system on arc Stick welder?
My old cable and holder is probably broken and corroded and I was wondering if I could replace the hole thing with a changeable version. 🤔
I recently got a Lincoln welder generator acdc. Now it has a switch that goes (ac/dc+/dc-). So, instead moving leads, I just turn the switch?
Only critique is for me being a novice watching to understand the 3 and the difference, it would had been more helpful if you’d experienced welding on the thin metal. The flip side, thank you for your no BS approach and putting that disclaimer on and being open and honest. Thank you
Hi Tim, I like to know if it is possible to do a reverse Polarity on an Inverter MMA welding machine ????
thanks
I saw a commenter that said EP, means earth positive, so (electrode negative) I heard there is less a player with E N. Electrode negative, but it is harder to not, stick welds, smaller ham maintenance required? Is any of this relevant?
Thanks very much! I like the tip about when to use DCEN. guess I'll try that for thin metals. What do you recommend for sheet metal?
6013 is my favourite rod, id love to see some videos of fillet welds with different rods, when i was learning stick sometimes i felt i got good penetration until i cut it on the bandsaw and could clearly see the parent metal zero fusion, mad respect to all the welders of all diciplines, metallurgy is facinating
thank you Sir!

Amazing
One big reason to use DC (instead of AC) is to avoid electrocuting yourself while repairing that dang piece of equipment while standing in the rain, sleet and mud!
Thank you so much for your intelligent presentation.
David Lixenberg
Your video fills the gap between explanation and practical result which in my amateur experimentation is that DCEN produces less holes on thin material!
I weld with DCEP and DCEN 3/32 6011 rod same amp setting. I got to say DCEN give better penetration than DCEP
I experienced the same thing
Just a question: Is there any sign on the electrode if It can run on DCEN?
Thank you.
You are Amazing!
Thank you! You actually explained it clearly enough that it can be understood by none professional welders. 10/10!!!
So what does that mean on a machine that has it listed as dcrp and dcsp I know it stands for DC reverse polarity and DC straight polarity but having a hard time finding information on these old terms versus the new ones aside from the little bit you went over in the beginning which basically means that dcrp is basically having it set at positive polarity so I am assuming dcsp is negative polarity? I'm a little confused but get the general gist of it
What a relief! An American who is not full of blather and deals with the subject professionally and with clarity.
super helpful. Thanks.
Is dcep the same as 'crisp' and is dcen the same as 'soft'?
Generally, I’ve used those terms relating more to short circuit MIG welding where the arc is not continuous. With stick welding, the arc is always on so those don’t apply as much unless you’re whipping and then that would be controlled with a dig or arc force setting if you had one. Polarity will really just affect penetration with stick welding and DCEP is almost always the better option.

very clear explanation and direct to the knowledge and clear talking technique, really thank you.
I appreciate you doing this. Thanks Tim!
Can you run 7018 AC electrodes on DCEP?
Yes, DCEP will work great. 7018AC has some arc stabilizers so it won’t go out when the polarity switches on AC, but it still works great on DC.
@@TimWelds Thanks. I accidentally picked up a box, and didn't realize until after I opened the box. Didn't want it to go to waste.
Exactly the information I was looking for thank you.
also scen is how you use your machine to weld with 7018 electrode
Good explanation! You can use naval jelly (rust converter) to etch the metal and see the penetration better! Couldn’t really see yours to good!
Thanks! Naval jelly is a great option because it's available at the hardware store. I've found the nital that I used works better, though I was also disappointed with how it showed up on camera in this one.
