So I have what I consider functional welding skills and have done a bit in the past...... Even taken a course in it. Mainly I have done some stick and gas, as well as, some mig, but mostly I farm it out to my favorite welder who uses tig and is exceptionally skilled in my opinion.
Here is the problem. My car is down due to some front end sheet metal fabrication and I need to weld (or at least tack weld) some stuff back together for strength. this would involve getting the car towed to his place and try and him getting it done before I go to work (60-70 hours a week right now) so I don't have time right now to do it.
So I am at the pawn shop today looking for a used welder and see the following:
mig = $300
flux wire feed = $150
baby stick = $50 (1/16-3/32 rod)
All were in okay to fair shape and all were middle to low end manufactures.

the stick would get me by (70 amps)

the flux wire feed I think was 80 amps (do these work well?)

the mig was in the worst condition of the 3 but then again I only
need it once in a while and it would probably be okay (90 amps)


any thoughts would be helpful

thanks

You can only weld sheetmetal with a mig. Not the others. Thin sheetmetal is hard to weld. I don't know if that mig will work.

I have a brand new unit...lots of experience with MIG...and even at that...lots of blow throughs on old metal.
The new stuff is OK...but trying to get it to stick to old metal is a nightmare!
The best solution (if you have the room) is to cut back to really good metal and then go ahead with the MIG and hopefully lots of luck.
