The power source is what the ignition and Lichtbogestabilität As absolutely equivalent to about five times as expensive "brand appliances" .Insbesondere the lower power range the arc is extremely stable. For MMA welding the machine is almost too good. Ground wire, MMA welding gun and the other "accessories" are junk, and you should discard immediately. For TIG tube package is long enough and works flawlessly despite very simple feel. Basically, TIG - devices sensitive than MMA machines. (Also applies rectifier devices, not only for inverters). The last "small" TIG device that I had cost 2800, not worked better and was after 6 years break. (New board not available!) If the Berlan now after one year gives up the ghost, which I do not think it's in the price still a better buy than as an overpriced brand device. Missing actually only AC, but there is not in the price range. Strong buy recommendation from SFI
