yes those aren't relative much anymore and I'm sure there's a guru who'll jump in and say they do everything with them, but the only way to go now is a wire feed welder with argon gas... I just have a cheap Harbor Freight wire feed welder that is flux core wire. It does the job okay but doesn't leave as nice or welds as the argon gas.. I was just teaching my customer yesterday how to use his new argon gas welder with his 51 Chevy that we are notching the rear frame 4 a lowrider airbag deal...
