Seen one of the above forsale old but never been used an boxed, its fairly cheap and on budget thought might take a punt.... but i cant find any info on it or prices so not sure if a bargain or not £70
Never used one, but would expect it to weld between 1.2mm to 2.5mm. Might get a bit lower than 1.2mm with care, but don't bet on it; it will have few settings. Do you know the lower amperage output?
The problem with m/cs like these is the lack of settings and the lack of range. They are either right for a particular size of job, or they aren't, there's not a lot to play with apart from torch technique, which again is limited by the power range available.
