I've been a welder for many years now, from welding in production facilities, to maintenance, into supervision and then moved into inspection.
One of the first things I have always taken note of, one that actually tells a story about the welder doing the work, is how well he/she keeps her equipment. One of the first things I take note of, equipment wise, is how clean they keep their welding cup or nozzle.
Its surprising how many people have come upto me through my career, asking why they keep getting porosity. They say they've "done this" or "done that" and nothing works, they're stumped! It's as equally surprising how many times the answer has been the first thing I check, their cup or nozzle.
Cool video buddy, keep them up. In my opinion their should be more content like this on UA-cam. Thumbs up👍
Bro, you're all over my feed, every search is your video.
You're going to go far, keep doing what you're doing. One youtuber from another, you're doing it right.
Hey thank you! That’s good to hear! Such a slow grind but all good. Having fun with it and just taking it a week at a time🍻
Great explanation from a real pro that knows his stuff! Was, also, impressed by the fact that you started to heat the runs, gradually... waiting, patiently, for the puddle to form, not by flooring the pedal, like most welders tell us to do.
+1 for his online program. I genuinely think most online teaching is a scam, but I’m doing it currently and I’m learning so much. I’m a total amateur, but I’m really happy I did this class. Was able to patch an aluminum radiator for my dad this week. Wouldn’t have touched aluminum a few weeks ago!
Hey its good to see another left handed welder. I'm left handed and learning to weld and everyone I work with are right handed, so it's a bit of a challenge for me.
I've been welding arc, mig and sub-arc for over 35 years. I've struggled with tig on aluminium since starting two years ago. You videos have helped so much, thank you from Wales UK !
You will get it just stick with it. I had trouble when I first started now I’m good but still welding and learning
Great video Dusty. I like that you explain why things are so important.
I would like to point out the end preparation of the tungsten electrode is based on the physics of generating the arc. I prefer having a pointed end as it is better at starting arcs and it will erode as the welding progresses. The angle of the electrode tip depends on the amount of current that is passing through the electrode. Generally for lower amperages, the angle on the electrode tip should be smaller. For higher amperages, the angle should be larger. Another important point about preparing the point is that the grinding should be done along the length of the electrode, and not around the circumference. The ball type end that you prefer results in a wider, or larger diameter, arc on the material. This reduces the energy input per unit area and may be helpful with thin materials in order to prevent burnthrough. The sharp point end has a smaller area that the arc energy is being directed at. I have enjoyed watching your videos.
That was terrific. I liked seeing the timing of the arc application and feed of filler. Very informative.
Thanks for the tips man, I got selected in my class to participate in the skills Canada comp this year this was a big help with my fit up game. 👍
You're an excellent instructor.
cheers, been looking for that kind of detail on this issue. Nice work Kelvin.
Great videos Dusty - thanks for taking the time. Re the fit-up of the work pieces , I like to lay the plates on two sides of a block or square tube or whatever else I have about. This gives easy control over the plates and you end up with the plates at 90 degrees
Thanks for the video I just started a new position at my job I’m finally welding. I love it and I’m still training getting to know the ropes. I get nervous when my trainer watches me but I’m getting comfortable.
Thank you for the nice educational video. Especially the clear explanation helped me.
Absolutely Paul! Glad I could help in any way!
I started welding Aluminium months after I've started binge watching this channel. First beads and outside corners were near perfect 👌(inside corners are way tougher though).
Thanks a lot Dusty, best teacher, most fun to watch :)
the recovery on the weld is one of the best seen so far, very well done helps to understand good
💪💪💪
Grat video Justin! Thanks for shearing your knowledge
Thanks, just what I was looking for
Glad to see you use the Canaweld machine. Great job. It's hot as balls
Beautiful Work
Thank you. Sincerely I thank you.
I just learned how to fix some of my biggest tig welding frustrations in just 2 hours of watching pacific arc tig. I have been a welder for 25 years. Amazing talent and refreshing positivity!
Great video topic. Great to dial in on the simple things
Always good to show the little details:)
Nice work Dusty!
Your videos are amazing
you are very good, I am following many welders on youtube, you are one of the best, you do some fantastic work congratulations
Thanks! I appreciate you checking out my vids! Cheers!:)
dude cheers for the vid helped me out alot from Western Australia
Yeah mate! Happy I could help! Hopefully I can visit your country again soon...! Miss traveling there...! Cheers bro!🍻🍻🍻
I just started watching, great job!
Thank you so much for this video. I have been struggling with aluminium welding. After watching this and filling your tips/instruction I managed to do some good clean welds. Thank you again 🙏🏻 watching from the UK
Wow awesome graham! Glad I could help! Cheers my friend!
Thanks for that, Top teacher.
This was a great video. Thanks for the info!
Awesome! Glad you enjoyed!🙏🍻
Really clear explanations thank you. I like the slow speed you did the tig weld at, I've maybe been going too far with variable results. I'll have a go at going slower! Cheers from Christian, England
Cheers! Glad I could help!
I found the video to be very useful. Thank you for taking the time to make it and you have a new Subscriber.
Thanks so much Mark! I really appreciate that!
Hey Dusty, can you make a more brief video on Ac balance and frequency and how the both affect the weld bead/pool?Thanks, like always love watching your videos. I've learned a lot just by watching you over the screen.
Nice work!
Great tips bro
Appreciate the knowledge you are spreading, Brother! “Each one teaches one.” mute ego and let Kung Fu flow, and the hard work and dedication to craft will equate to love. Love of craft.love of life.
Helpful... thanks man...
Great TIG tips, it would be nice to get a shot now and then on what amps your your welding at with the pedal.
Nice application, plus good explanations on torch cleaning, etc. In almost every tube video, the chosen material to weld is what I consider quite thick and many have the material laying on a nice heat sink, which helps burn threw. Current project is .049" tubing with 90 degree joints. Material is squeaky clean, but having problems with frequency and balance. This is a new inverter machine, which replaces an old transformer unit. A video on doing really thing, .020" and up to .050" material would be a real help.
Hmmm. I did an episode on thin stuff a while back, that may have some tips there? Can’t recall exactly whst I covered in that one 😂😂

Howdy Dusty - Kelvin here. Thank you very much for this - perfect. Really enjoyed it and that’s going to help me heaps. Cheers.
Awesome! Glad I could help in any way!
Cheers from Nanaimo, great channel!
😀really interesting video so helpful THANK YOU
Excellent
Awesome info, be sure to let you post flow cool your red hot tungsten before removing it from the weld zone, not doing so will allow oxides to form along the tungsten
Great videos
Thanks!
Hi good morning I am trying to learn how to do tig Welding I am going to buy a Welding machine to practice at home and your teaching is great thanks for your help
Love the video
Nice job thanks

awesome video! Im just about to dive in with Tig welding aluminum and how to tack was my first question. how do you prevent aluminum from warping when you do these long corner welds. Aluminum conducts heat much more than steel and is simultaneously softer - Ive had problems with warping when welding steel plates that need to be perfectly square - would imagine its even more of an issue with aluminum
i love this channel
P.s. dude, I just made an awesome discover today I think, was listening to arc junkies podcast and heard about "The Welder" and "The Fabricator" magazines, both are free subscriptions just require basic info about ur job/business and what u like about metal work. And 2 or 3 of the newsletters and magazines said "Canadian Fabrication" and "Canadian metalworking" I subscribed of coarse, Figured YOU might have an interest in that. Peace my man, keep it up! Also, dont get that "heat catch hot as balls" lmao so many jokes in this one, musta been a happy day
Ha most days are happy- I just let my smart-assery show through sometimes 😂😂 Thanks so much brother. I always appreciate hearing from you 🍻
Lindo. Simplesmente Brutal . Parabéns
you are awsome bro keep being you
good job
You have a good sense of humor. You keep saying you’ve been welding for 18 years, but you look like you’re in your 20s, so when did you start, when you were five? Or do you drink some elixir the rest of us don’t know about?
😂😂Damn well this comment is probably my favourite !😂😂 I’m 37! But I for sure act like I’m in my early 20s! I’m glad you dig the humour! My wife is FULLY sick of it believe me!😂
Cheers my friend 🙏
He looks 36-38 to me so he started at 18 or 19 makes sense to me.
Oh shoot I just seen the answer No offence you do look really young I’m just pretty good a guessing ages
This was a great one. Just starting to try TIG welding.
Cheap 90 degree clamp will help hold things while tacking as well. But that's nice trick in a pinch.
Thank you Something to aim for
What gloves do you use for tig. This is the best video I’ve seen of yours so far 👍🏽
Please today is my first time watching this video and i really enjoyed your work but am not a wielder and i want to learn and have not been schooling to learn how can i practice it by myself
Hi Dusty, enjoyed your video.seems like I end up going a lot faster as I continue welding. Maybe to much heat . I try to back off on heat . Just need to practice practice practice. Thanks.
Hey Larry! Practice is key.... and patience is as well. Sometimes a little slower sets it down just right:) Cheers!
Great Video! I was wondering if you could possibly explain how to weld two square 1" tubes together at a 135 degree angle (or any degree really) Wall thickness I am working with is 1/16. I am having the hardest time with the settings for this. I keep blowing through the material. As well as I keep over cutting my angle so when I make the bend together the material is not lining up correctly causing a gap. I would love it to see a video on how you set up for TIG welding 1/16" material.
I'm going to build a DYI Ultra Helicopter. Would be great to see fit up tubing and Aluminum tig welding that would pass FAA inspection
Thanks mate for your effort. Like your style and the quality of your takes - plus I get everything you explain, although I'm not english spoken.
BTW: One more verry Important thing ☺️ Never cover the air outlet of your machine with these boxes 😶🌫️
Nice video dusty . Keep it up mate . Have you done a video showing how to ball a tungsten properly ???
Kind of...😂 I’ve done it in a few of my episodes, the tungsten episode I mention here, but I should do an episode specifically on that subject:) Thanks for the reminder:)
you should do another one but use dirty consumables and show us just how difficult it is to get a good weld
I like your videos; pretty entertaining and educational. I've been doing recreational mig welding on and off for about 25 years. Last year I decided to play with tig. How hard could it be?
tl;dr - After hours of watching instructional videos and practice, I still suck at tig welding.
Give me a lap weld, and I can do ok from time to time. Butt joint and my success rates plummet. Filling a gap? Forget about it.
One thing that would be nice to see a video on, are techniques for recovering a botched weld.
I find myself having a touch of success, and then I might take the tungsten for a bath, accidentally put too much heat into a joint, or the weld just goes south for some unknown (to me) reason. Then I end up just making more of a mess.
If it's practice you can obviously just start over, but if I'm 3/4 the way through a schedule 20 SS turbo manifold, I'm not throwing all that away.
Waying in on tungsten, industry basic is 2 percent thoriated if your using an automated tungsten grinder it will put somewhere around a 5 to 10 degree angle, I like to keep a half Inch pipe nipper capped on both ends with about a dozen or so tungsten already ground. I personally like to use a small battery drill to chuck the tungsten in and put my 10 degree taper in. Like you said it's a personal like. If your welding aluminum you don't have much choice, your going to wind up with a ball on the end anyway with high frequency.
Thanks bro, I was able to achieve something today…..
Great Video bro Keep it up. Stay Safe..
Thanks brother! Hope you are well!💪
I know it has been a minute.... But I think a decent idea For a future episode with be doing your own version of the aluminum drill.(turning padding beads on a thicker aluminum plate into a fun artistic project) running Different settings, different directions, using different hands, rods/consumables, whatever lol kinda like Jody's versions, but the Pacific Arc Way! :) peace brother! Hope you are well!
Nice explanation Eeh. Maybe I missed it but did you mention the cfh setting when you set up your machine? Also I have a rookie question on gas lense cup screeen defuser. Two Installed into the cup and one of the screens getting partially melted. Any thought on the cause of something like this?
Thanks for your effort and willingness to share your advice.
Suggested topic: differential diagnosis ie distinguishing between the various different reasons for getting cruddy welds.
E.g if you've been welding successfully over the last half hour on the same material with the same cleanliness and the same welder settings etc then either you dipped the tungsten or maybe the breeze increased, or you're running out of gas. Got to look at what changed. No point looking to change weld parameters when they were ok 5 minutes ago.
But if you are starting the day, it could be many more things.
And if it's a piece of scrap or a repair job maybe it isn't a weldable alloy???
Troubleshooting 101.
Amazing idea. I really appreciate the suggestions! Cheers from Victoria!
@@PacificArcTigWelding oh you're in Victoria? Keep safe eh? Mask up!
And greetings from Ipswich by the way! :)
Rocking the bandana these days😂
Cheers my friend!
I would like to see some "difficult positions" aluminium welding, like when you can't put on the table what you are welding and flip it how you want it would be really helpfull.😇🙏
Could you please talk about why would you prefer to use a cup #8 instead of #5, I've noticed in one of your first videos u said you were using #7 and one of the latest videos you used a #6.
Greetings from Guatemala 🇬🇹 central America
Dusty, I have experience with MIG (GMAW) and stick (SMAW) welding. Soon I will have a need to weld two automotive body panels together. Because of the location it will need to be a "butt" weld (side by side) and I prefer that when doing auto body work but that's another discussion. Normally I MIG this and don't think twice. However I am considering venturing out of my comfort zone by purchasing my first TIG box. I've been kinda looking for a reason to do that and maybe this is it. However I wanted to get some feedback and perhaps this is worthy of consideration for an upcoming episode on your channel. I would of course practice on several scrap panels prior to attempting it "for real", so let's set that element of the equation aside (ergo I will do my homework). That said, the rough idea/game plan that I have in mind is to join the respective panels together with little to no gap, then use the TIG torch to "fusion weld" the panels together. From what I have read "fusion welding" is when you increase the amperage on your TIG box to significantly more than you would use to weld the same material together, then with just a quick burst via the trigger, you join the two work pieces; and you do so without the need for filler/rod. It sounds interesting, but I have some concerns about it. The first being whether or not the height of the resulting "fusion weld" would rise to the surface of the base material. Almost seems like you'd have a bit of a valley rather than a crown. But this is getting long so I'll stop. Any feedback is appreciated and a video would be incredible! Thanks!
thanks
3mm - that ain't thin - try some 1.2mm. Our miserly boss bought a whole pallet of 1.2mm sheets on the cheap, and what a nightmare. He doesn't realize the extra time taken to weld it, offsets the cost saving in the material. Anyway, it's a good challenge. Good vids man, well presented.
Wow. This is incredibly inspiring. Thanks, man.
for the sake of familiarity, can you mention some of the settings (or all of them) you are using with each example? Some environmental variables too, Ambient temp / humidity. Material, mode, thickness and main amps would be nice. I'm all for try before you try and figuring it out, but having some expectations is nice too. Starting to think my welder is balance reversed. Tried an aluminium piece and it ate the tungsten.
Hey Dusty
You have mentioned creating a tiny ball on the end of your tungsten to help with arc stability. Can you demonstrate your technique with balling the tungsten for all of noobies? Thanks! - Mark
I only do stick welding stuff around my house, but man I really love your channel!
Loving your vids man
Question, I have a DC lift tig and new to welding
And tips for welding Ali specific to using DC lift?
You cannot weld aluminum with dc you need an ac machine.
A bore brush for a shotgun would probably work pretty well for cup cleaning.
Mad skills my friend, keep up the excellent work dusty 😁👌
Thanks dude! Gotta keep practicing still for sure! Never done learning!
OMG! Damn dude, that "I hope so." bit had me laughing so hard hahaha 🤣 just the way you said it made it seem like u have dealt with many who havent or dont at all. Lol also, that dirty cup looked like a mig nozzle after long duel shielded weaves. Great video as always my brother! Hope ur doing as well as the jokes in this vid(exceptional haha)
Haha. Yes. I have taught some smelly welders. It’s been a problem...😂 And yeah that’s exactly what that cup was😂 Just mocking it up for a laugh🙏
Man, I would never let my MiG get that way.
😂😂😂I’ve seen TIG cups that look that bad before believe it or not 😂
@@PacificArcTigWelding dayum! I just cant conceive this lol like, talk about bad hygiene
@@melgross I hope not lol i dont either, some guys at work like to, like i said, if they've been using dual shield manganese wire and making LONG weave runs on 3/8 manganese plate, kinda hard to avoid if uve never done it(ALOT of spatter) but I always take take to keep it clean. I do this with everything tho. Mild steel mig i can use a nozzle for months of everyday use and it will still look clean n nice. Keep up the good "weld hygiene" lol
did you use the same settings that you set for your tacks? or just lifted on the pedal. Great video...maybe a little to critical on your weld. Wish I could make mine look that"bad". Mine kinda look like seagull poop.
Do you clean your aluminum filler rod as well, also what voltage were you using 120 or 220 V
Hey buddy, where you from? Ontario here. I'm building a tig welder which will have AC, adjustable +/- percentage AC as well, and adjustable overall frequency, as well as of course adjustable output current. All the little bells and whistles too like taper on / taper off, delayed gas turnoff, pulse mode with variable pulse lengths, high frequency arc start... that's pretty much all the perks I think. Oh, and the system will double as a plasma cutter, as well as work as a stick welder. The IGBT heatsinks are not finned... instead they are mounted to a solid block of aluminum with tunnelling drilled throughout for liquid coolant to be pumped through. Only makes sense to get the water cooled TIG torch if I'm going to be pumping fluids around anyways, right?
I'm just about 75% complete with the build.. the longest part of the project has been simply researching how exactly the output of a TIG welder behaves in order to control the output current as well as it does with the potential for it to be going all over the place since the electrode is being moved around constantly, as well as the conductivity of the part surface constantly changing due to the rapid swings in temperature it experiences as well as the constant changing dimensions of the weld pool, and the constant changing dimensions of the actual arc as it is blown around by inert gas as well as dealing with all the other constant variables in flux around it I just mentioned. So yea. Finding which solution was the best for my situation was very tough. In addition, for some reason it is not very easy to find an actual schematic diagram of any of the high end TIG machines which are what I really would have loved to emulate as closely as possible. In addition, I couldn't really find a whole lot of information on the type of waveform achieved by the output of those high end TIG machines. It took me ages before I realized I would have to initially convert my 240vac to DC via rectifying diode bridge, then I'd need to convert back to AC with an h-bridge inverter, lower voltage, higher current, and this time AC at a very high frequency (minimum 15khz). The high frequency allowed for a relatively small ferrite core to be used for the transformer of the inverter. After this, the current was once again rectified back to DC, then an additional 2 IGBTs were utilized in a way that allowed for the final output of the system to be AC at whatever frequency was desired, even having unbalanced AC waveforms with longer + halves and shorter - half cycles. You could also just leave one IGBT on and the other off to have DC output as well. For the most part, I believe this final 2 IGBT stage will be set to produce an AC welding current of 250hz - 400hz.
whew that was a long one! Thing is.. I barely have any experience TIG welding! Actually I don't have more than 10 minutes on a TIG machine! I did a lot of very thin MIG welding, which I consider to be like welding with a toy rather than doing anything that requires skill. Let me know your thoughts on my project here, and if you have any suggestions!
Subscribed just for the art 8)
Steve that’s awesome! Thanks man! Got an art one coming out on this Thursday....!Cheers 🍻
were you at full pedal during the weld after you started dipping? thanks
The time between dips of the rod was sometimes short and sometimes long. It was not regular. Is that because you are waiting for the puddle to spread out to a consistent width? I’m sure it isn’t random because the resulting weld is awesome.
Can you do a video on tig welding thin aluminum? I feel like it takes a while to heat up but then it’s so hot that my puddle is all over the place. Also, I can never keep my tungsten from going blunt when welding aluminum. Thanks
I’m assuming you weren’t full pedal or the full 140 amps on the tacks. About what amperage were you using for the initial tacks
How do you get the ball on your tungsten? I’m very new to tig welding .
What amperage were you welding that bead with? I feel like if I go that slow, I will blow a hole through my aluminum unless I'm using like 1/4 pedal on 120amps on 1/8 aluminum.
I subscribe to your channel great tips mate. What is your preferred tungsten to use for ali welding? Thanks
My TIG Tacks never work. I honestly dont know how you do it so easily. I either blow a hole, or I get a crust. Cant find the correct current. Just forget about doing a TAC on the edge like you do. I blow either a V or a crust. I have very good machines, so I am the only one to blame. TIG is very difficult if you dont do it every day. I moved to Gas MIG and it suits me way better for my on-off schedule as there is not as much detail to remember as TIG,. TIG welding is one of the last TRUE trades and I take my hat off to someone that can do it this well..
