I managed to weld my exhaust with a 90 amp flux cored el cheapo Harbor Freight welder I found off of Craigslist for $40. I did buy some better wire. Used 3/4 EMT. It was a learning process because even at MIN the thing runs about 60 amps and feed speed at 1. I did figure it out, though, you just have to be quick and let it cool down. I'll post some pics when my phone recharges. It ain't pretty, but there's a buttload of wire on it and it ain't going nowhere.
