Here is a link to a follow-up video where I use aluminum stick rods and flux core filler rods I found. https://youtu.be/DxQszHt4YFs

When GTAW was first developed for aluminum, it was called heliarc welding. Used extensively in the 1940s and the 1950s, it required DCEN and pure helium shielding gas. In the GTAW process, the electrode negative (EN) current provides maximum penetration, which is highly desirable. Then people realized that there were advantages to using AC for aluminum GTAW.

I have successfully welded aluminium with TIG DC and pure argon, but with 2 very big differences; the aluminium was preheated to 130 degrees Celsius and fluoride flux for gas welding aluminium was used. Sticks MMA for alu can be used also, it has the good flux and these sticks can be found easily. That does not replace a good AC/DC, but helps a lot for an occasional weld on aluminium to fix something fast.

I enjoyed this work. With an explanation of the differences and comparison between alternating current and direct current, each on an aluminum plate.. Your explanation of this device is very beautiful and your style was educated and well-experienced.. I thank you for what you presented and forward, my friend.

So in a nutshell, Ac Tig is the best suited for aluminum and iron, this holy grail of information thanks🎉
-
Your video is a lot more clear and concise than most on this subject, so thank you very much.

I'm strictly an amateur welder, shopping now for my 1st TIG welder to replace my cheap HF flux core machine, with the intent of welding steel and/or aluminum. This was by far the most detailed and concise explanation of exactly why I will want something that provides AC and DC. Thank you so much for this demonstration!

If you want to do a very interesting video that will amaze people do the following. Go grab a package of Hobart or Blue Demon Aluminum Arc Welding rods. Then do this same exact video using those flux covered rods with the DC TIG. It will amaze you and is an incredible field hack. Also if you pre-paint the area with a flux it will help.

I don't think I've ever heard this topic put so brilliantly, thanks.

Great answer for the skeptics. Great answer for the experts. Perfect video
-
Thank you for your excellent presentation on argon & helium DC Tig on aluminum. Also a good explanation in the comments section on spray transfer using a DC mig spool gun to aluminum
-
Cool video, and thanks for answering my question! I completely understand why AC or helium is needed now.
-
Awesome video thanks! Straight to the point and great camera angles and welding clips!
-
Thank you, Now need a video on the cheapest AC Tig welder than can weld aluminum..
-
Very good video. Thoroughly explained. I love the way you compared the two!
-
I woke up today with this question. Thanks for answering my question so nicely!
-
That was exceptionally well done, I very much appreciate the time, effort and clarity of the video. Thank you

You can TIG with DC but you need your tip or the tungsten to be + and it will weld as good as the welds he is doing here. Be careful with the amps as you will go threw your tungsten rod pretty fast but you can get the job done ..
-
Great video , a lot of ground covered in a short space of time.

I have had amazing results welding alu with DC TIG, and without using any gas at all! (for the welder) But it was costly, but soon it will be much much cheaper with Musk's Starship, the main problem was getting to the Moon and back.
