Purchased a 120 MIG welder recently. Not sure how to use it yet. I picked this one because I can use it on a standard grounded three prong outlet for home use and because it is supposedly one of the easier ones to learn and use. Also, I liked the idea of being able to use flux cord wire without the use of gas shielding. I want to use this for building cool stuff and welding aluminum. Does anyone have any pointers or tips?
