Back in my younger days I worked as a mig welder in a factory. I always wanted one at home, but all I ever had as a stick welder, and a small 110 volt wire welder. The ones I used in the factory were 240 volt, used CO2 gas, and were head and shoulders above what I've had. It's not a matter of not being able to afford one, it's just that I never figured it would be cost effective.
