Aluminum MIG Welder: The 250amp gas-powered mig welding machine can weld aluminum sheets, with its own single-pulse technology, and will not weld through the sheet. - Welding current adjust range (A): 10 ~ 250Amp.
only used it as mig so far i think its good value just for that
after setting up using it for first time it feels smooth voltage is uniform constant it may be because its new it gives you confidance to use on thinner metal the fan is audable but shows its getting good cooling this welder is one to look at if it stays reliable well werth the money
