Re: Harbor Freight Mig welder
Most any of the better quality machines will run aluminum wire. Ask before you buy. Check out your local welding supply stores instead of the big box, Home Depot, Walmart etc. You'll get better customer support and they occasionally have sales just like the retail outlets. Some of them only sell wholesale but they're the exception. Most any large city will have several welding supply places and the guys / gals who work there generally know their stuff. Good luck, easy ridin'.
