This video is about tig welding aluminum techniques for butt and tee joint welds.
basic settings are 100-140 amps using foot pedal so basically what that mean is at times I am at 140 amps but also much lower when heat soaks the small practice piece.
i used nearly 140 amps but when the aluminum gets soaked with heat, I used the foot pedal to use less amperage.
AC balance set to 30% cleaning, AC frequency set to 100 hz using advanced square wave. pre flow set to 1.5 sec and postflow set to 8 sec.
3/32" 2% lanthanated electrode, and 3/32" 4943 filler metal.
4943 welds a lot like 4043 but has better overall properties than 4043.

for the butt joint, I used a #6 cup with 15cfh of argon, and for the Tee joint, I used a #8 furick pro clear cup to aid with filming the arc.
I increased the flow rate to 18 cfh for the #8 cup but all other settings were same as the butt joint.
