I forgot to mention. I don't have a garage anymore so dragging out the big welder is somewhat a chore so I bought one of those small raceway or speedway welders from ebay. It's a small green gasless mig. I bought it simply for small crap like exhaust work and stuff. It was only $120. I tried it out not expecting much out of it with it being gasless but holy crap. I burned right thru 1/4 steel welding the seems together. I figured it would just glob up on me. I actually had to switch it to low for my exhaust. It will never come close to a real gas mig but it's was worth the money. Actually it was worth the money just so I didn't have to get help to lug the big one out of the basement. Just a thought. Not sure what you need it for.
