You'll not be happy with it for anything more than body panels. Up to 1/8" steel will probably mean very cold welds when you are there trying it. I have one that goes to 105 amps and it does just OK for 1/8" thick material. I usually end up taking that type of thing to work and borrow the big'un.

Try to get one with gas option too. You'll be happy you did working on body panels. Flux-core is fine for small construction projects, but not something you'll want to deal with on spot welds. Too much cleaning.
