just picked up a new welder this weekend, well new being relitive. it's an old craftsman a.c. arc welder 40-230 amps. seems to work although it needs all new cables and a fresh coat of paint. now what are some good uses for this thing? would a TIG rig be a bad idea? i don't think i have done any AC stick welding is it all that different then DC? what rods should i be looking for?
