I bought mine because my cousin works for a welding company. In talking to him, I found out his company used to sell these Eastwood units. He’s a helluva welder and said for the money, they are hard to beat, price wise. I bought it mostly for sheet metal on my Duster, but have welded heavier gauge too. If it gets real crazy, my dad has a stick arc welder and I have a friend with a high amp mig/tig welder
