Tig welders - discuss

Hard to go wrong with a Miller. Make sure it'll do aluminum if that's something you want, has to be capable of welding in AC with a constant high frequency. The duty cycle is even more relevant with a TIG than it is with a MIG, so you'll want to get as much duty cycle as you can afford.

I'd offer more specific advice, but I use old Miller's. Like 1972 and 1974 old. My MIG is a Millermatic 75, my TIG is a Miller 320 A/BP. No fancy settings like the new ones, but that A/BP has a 100% duty cycle at 200 amps, so I could probably get into the battleship building outfit if I wanted to. ;)
