A very inconvenient device, the first device presented to me and it does not have a cheap carrying handle, which is terribly inconvenient. Very short wires if you need to weld at a distance of one and a half meters in height, expect to hold it under your armpit. Since, again, there is no penny pen and smart-ass wires per meter. In short, who needs this I can sell for a penny. Cooks well, but the shortcomings in convenience cover all the pluses.
