Hello. I am looking for a welder for my home. I have welded a few things before but not often. I currently have 220v on 10-3 wire running out to my garage maybe 50ft from the house. I was searching craigslist but am not really sure what i am looking for. I do know i dont want a stick welder and i cannot afford a tig. I would like a gas mig welder. I want to be able to weld 1/4in steel. I would like something with full heat and wire speed control. I am not to sure what options welders even have. I know its tough but I am looking for something used for $400 or less. I see a few millers and lincolns for sale around that price. I need some basic schooling on welders and would like to know what you use. Thanks.
