The deepest deep dive into the old school practice of balling tungsten in preparation for welding aluminum, and why it's pretty much obsolete these days. In this episode, Justin walks you through the history of AC welding and why modern welders don't ball the tungsten when welding aluminum (or aluminium for you others we read in the comments). Enjoy!

Thanks, Justin! I was in a CC welding class last spring where the instructor was still insisting we had to ball our tungsten, even with state of the art Miller machines.

I only recently full balled the tungsten, and just like you say, I had much less controll, and could see less. Very interesting to hear he "that's the way I've always done it, and my grandfather's grandfather has done it" story.

I appreciate this video. I took welding in night classes in the 80's just for my own knowledge. We were taught to ball the electrode when TIG welding aluminum. I've welded numerous projects using Ocy/Actyl gas welding, ARC welding and MIG and over the years purchased all the machines to accomplish that. I never pursued TIG because I was just doing hobby-shop work and couldn't justify the cost of a TIG unit. Fast forward 40 years...... I have a friend who has a TIG machine (and he's not sure of how to use it) and we had a conversation about technique. He was talking about different colored electrodes and that you don't ball the tip, etc. I was totally lost as that went against everything I had learned so we didn't get very far in the conversation. Your video explains a lot so I think my friend and I can resume the conversation. Would you happen to have a video on tungsten electrode selection? Thanks for posting and I've subscribed.

A few things, it would have been heliarc in those days with 50hz. 60hz didnt become a lot more common until mid 60s. This is also around the time gtaw sheilding gas experiments were getting more in depth and playing with different alloyed metals in gtaw. Then we started to see the viability of simply tig welding aluminum. As most applications dont require the added heat input of helium especially on thinner material. You also do not need to ball the tungsten. All the balling does is reduce transfer of tungsten to the workpiece and maintain stability in the tungsten. If you size your tungsten bigger the tungsten will only barely ball on the tip. Grind angle and quality is important when doing this. Thoriated will resist the balling throughout. Yes even on transformer machines. Most applications do not require modifying the ac wave. Balanced can be helpful at times also. Mainly on castings or broken down aluminum repairs. You can also weld aluminum on dcen if proper cleaning precautions are taken and the amps are set correctly for desired penetration thickness. A little helium helps too.

I am definitely in the don't ball camp. Even if you are using an old machine that is 50/50, your tungsten will then naturally ball as you are welding, so pre balling it is a waste of time.

My 460 amp Miller has balls! It is a 1965 Goldstar 330 abp. 23 years ago, I was taught in college to ball the tungsten but we had syncrowave machines. If I recall correctly, we may have just done a small ball on the tip. The semester before, I got the 330abp at home and taught myself to tig weld from miller's web site.......no youtube back then. Most of what I tig weld is steel with some stainless thrown in and only occasionally aluminum, and a spoolgun is sometimes a better choice on the miller 211 inverter mig. Lately, I have just sharpened the pure or lanthanated tungsten to a point and blunted the end, like I do for DC use, then I let it ball on it's own. We did use only thoriated on the syncrowave machines, if memory serves me right.

@TheMetalButcher 25 күн бұрын

I have a 330A/BP as well. So you are saying for aluminum you just use lanthinated and blunt it? Or do you use the green?

@CGT80 25 күн бұрын

@@TheMetalButcher Originally, I was taught to use green. After watching videos, I tried 2% lanthanated, blue. It handles more current but seems to work the same as green. I sharpen and then blunt the end, the same as I would for welding steel with 2% thoriated. Recently, I tried balling the lanthanated after sharpening but I don't recall if the arc was more stable. My biggest problem with the 330abp is the arc wandering when doing ac on aluminum. Aluminum and stainless are something I only occasionally do, so I'm no expert at what is the best method for the old machines like our 330's. For aluminum 1/8" or thicker, I use 1/8" tungsten and run my power on the middle tap maxed out and control the pedal. It takes a lot of heat to get going. On 3/16 or 1/4 material, I will use the top tap (3rd position on big selector) and turn down the knob to 10-40 percent. The 330 with sine waveform just does not have a focused arc with deep penetration. I'm not sure if mine has issues or if it is normal for a since wave transformer machine. On thicker material, stomping on the pedal works. On thinner material, like 1/16" x 7/8" aluminum tube, it was very hard to get a nice bead and not burn through. The arc has a mind of it's own, even with cleaning and prep. That is when I tried balling the tungsten again. That part, I ended up grinding and blending the welds on. There were no voids, so the weld was good, just didn't look like a stack of dimes. The syncrowave machines I used in college were much better at making a nice bead.

Very timely video!! I run a 400A modern inverter machine in my home shop and infrequently use a 300A transformer syncrowave at work. Currently building some very large 1/4" wall tubing frames at work on the syncrowave and was balling 1/8" lanthanated tungstens and not seeing great results, especially on fillets. I'll have to play with the tungsten shape and balance a bit more tomorrow and see how that works for me. I'm also happy to have found your weld coach channel. I was a big fan of TFS and really liked your past videos on there. Lastly if you or anyone has other tungsten suggestions for the transformer machine that could also be helpful!

@joemurray8902 29 күн бұрын

Possibly (just spit balln' here) the reason why the first machine was set up to adjust the positive is possibly because for a long time it was thought that the electrons ran from +ve to -ve. That's because the multi meters gave a positive deflection when measuring the voltage and current. What they were measuring was the "holes" left behind when the electron jumped to the next hole on it's way to the positive terminal. Kinda like sitting in a moving train and measuring the world going past you thinking the world is moving and not you. So they thought the electron was moving to the +ve. Once they could detect the direction of the electron they realized it was moving from -ve to +ve. But by then we had a whole industry set up thinking in the opposite direction. Like I said, just spit balln' here.

So I have a 330A/BP, no balance control. I have only blue, 2% lanthinated tungsten right now, up to 1/8". In the past I welded aluminum with 3/32nd overdriven, and split a few ends. I had a dull tungsten, not balled, and it wouldn't ball. Would I be better off getting 5/32nd and trying to sharpen in, or go with the green and let it ball?

@hunnybunnysheavymetalmusic6542 11 ай бұрын

Hmmm... I wonder if my cheapo welder has that adjustment. That MIGHT be some of the reason I'm going through electrodes so fast... I'll check that as soon as I get in the shop. May be a game changer for me.

@blauesKopftuch 11 ай бұрын

It's not about getting hot enough to melt the aluminium-oxide, it's an electro-chemical process turning the aluminium-oxide back into aluminium. If it would get hot enough to melt the aluminium-oxide it would also get hot enough to vaporize (turn into a metal gas) the aluminium. Instead you can see the aluminium-oxide "vanish" with still non-molten aluminium "underneath" (it is not underneath, it is the same aluminium that was bonded to oxide atoms before).

@tweake7175 11 ай бұрын

nice video as always. it just needs a better way to describe the cleaning action rather than "melting it". technically i think its called cathodic reaction, converting the oxide back to aluminium, which makes most peoples eyes roll back in their head. sorry i don't know whats an easy way to describe it. also the big factor in balling is the type of tungsten used. more robust tungsten's don't ball as much as the old pure does which i think is worth mentioning.

Hi Justin. I have a question. I want to buy a welding machine(AC tig). But I found that it is locked at 60 Hz. So for example, instead of welding at 120 Hz 110A, welding at 60 Hz but a bit lower amps, would it be about the same thing ? Thanks.

@mikeiver 10 ай бұрын

Totally about balling but you left out the effects of frequency. Throw out at 200HZ or even 400HZ and the arc cone gets very narrow and controllable to steer on AC. Also, at home where I only have 50Amps at 240Vac I am sometimes forced to weld thick aluminum with DC. It is easy but requires meticulous prep and Helium. Single pass on 1/2" to a 1" plate, no problem. Another good video though.

@paradiselost9946 11 ай бұрын

"time, not amperage". mines weird. it has clean area width. thats cool. it also has clean area _depth_ and that, as far as ive worked out with my fiddling, IS amperage. doing really thin stuff i find its great with a 3070, but with a lot more current dumped on the positive... or at least, winding the depth up to +50. tend not to blast through edges as its the electrode taking the brunt of it. giantz. other than feeling a bit colder than the dial says, its been pretty damn nice for a chinese unit. knock on wood. a foray into selecting frequency might be good? again, from what i see... low frequency if you gotta get in deep, or positional... high frequency seems to make the puddle more liquid but less penetrative.
