A notice after making him "eat" 300 +/- electrodes. Well suited for casual use, the settings are sensitive DIN 9-13. Some small "delays" sometimes blows arc so early "sticking". The sensors get dirty quickly (still + in galvanized welding.) Must be cleaned regularly WITHOUT RAYER the screen. Disassembly of the polycarbonate transparent protection is impractical (fixings are fragile). Do not plan on outdoor welding s'i brightness are too many (but it is also valid for other models). So honorable vocation product for use "DIY".
