Nice work sir, great attention to detail. For tig welding al, a foot pedal is the way to go. For steel and stainless, you don't have the heat conductivity, so for all but the thinnest stuff just set it and scratch start. A really cool trick for that is using the filler wire, just drag it across the tungsten like a match while leaving it touching the work, so that way you won't break the tip off in the weld and get an inclusion. Doing al you have the high frequency for starting and stabilizing the arc, so you don't need that trick, but for steel it's nice to not have a damn pedal to drag around everywhere. Great work man
