I'm looking to buy a mig welder and was just wondering how many amps the output needs to be for doing a roll cage without having to stop to often i was thinking like 150.Just wondering what everyone else uses.Thanks

150 will be fine if you dont build too many cars at once

try to buy one with the highest duty cycle you can afford, i.e. 30% duty cycle=30% of one hour. I just bought a LIcoln 175 plus for building my cage and it works good for me, but I'm not planning on going into prouduction either. Be sure to buy a reputable machine like licoln, miller, hobart,just to name a few. also go for a 220 volt unit if you can. Good luck and have fun.

Let me state a Miller matic 135 is the new one runs on 110 volts. This is all you need, it welds up to 1/4 inch stuff. The 175 miller is also new but a 220 volt unit that is a little better of the shop.......

You stated you didn't want to stop too often, that has to due with duty cycle.....
like shadowz stated a 30 % duty cycle is 3 minutes welding for every 10 minutes.....
You can't get over about 50 % duty cycle until you get into a high end machine.

If you need more than a 130 amp welder to build a car you need to practice your welding skills. You are rushing the weld and not getting the proper penetration, puddle size,........turning up the welder is a crutch for a poor worker.

Most of what Jeff says is accurate, but if you have 220 in your shop you may want to consider the Lincoln 175 (the 175 plus is about $100 more than the regular 175, not sure if it's worth the extra bucks).
I had a Millermatic for a couple of years and it worked great for most everything except when I needed to weld the thick stuff like frame straightening tools and jigs out of 3/8" and 1/2". I traded in my Millermatic for a Lincoln 175 (T?) 2 years ago it works great on everything and I have been very happy with it.
Another thing I like about the 220 welders is I don't like loaning tools out, most of my friends don't have 220 so they bring there project to my shop rather than bugging me about borrowing my welder.
The lincoln 175 is the same size and weight as the millermatic doesn't cost much more and and is the unit I would choose again if I needed a welder.
