Hello all.

Hello,
Ive been arc welding on and off for a few years making brackets out of 10mm plate for the company I work for. I have had very little training other than a couple of lessons when I was in collage a long time ago! At the moment I use a 210 amp SIP arc welder which is on its last legs and I have been given the task to buy a replacment. The Boss wants to buy a mig. Is this the best thing? Ive only used a mini mig before gas and gasless. I know I could do the job quicker and with less mess but to get a mig at 200 amp and have a good duty cycle I think is gonna be pricy. Any ideas?

Welcome to the forum.

I think you would be looking at a mig of more than 200amps, it's never ideal to be running the machine at it's top range all the time, it will also be at the bottom end of it's duty cycle doing so.

So yes I think you will be looking up to a grand or even beyond for something like that, perhaps one of the heavy duty portamigs or similar.

Depending on how much you use it, and the supply, a used transformer based 3phase machine may be a good option.
