If you are having trouble with TIG because of less than clean enough metal then you will still have the same problem with a MIG regardless of the machine's quality.
Thanks, I must have mis-remembered that, maybe it was stick, or maybe it was just wrong and nothing welds dirty stuff better. But 90% of my complaint is needing two hands and a foot under the car.
And I agree that bigger is better, but I don't intend on using MIG for anything more than body panels that are hard to access as I like TIG (of course I have never used MIG). If this was going to be my primary welder, I would have just bought a Miller/Lincoln and been done with it
