After using this welder for several months I must say that I am very satisfied. At $100 it works very well. I've only used a 110 TIG weld at the machine's maximum amperage and it trips in my home circuit breakers, but the welder never stops (I used it on a 15 amp circuit). . One of the two Dinse plugs didn't even fit the car and I had to buy new ones to be able to use the car. The ground clip and stinger are no better, and the wires are copper-plated aluminum and very short. Unitweld would be better off selling the device without any accessories. But overall I am very happy with my purchase and will buy again from this manufacturer.
