Hi, complete novice here. I am thinking of buying a second-hand Clarke MIG130EN for bodywork repairs on a pre-war car. Metal thickness is about 0.8 mm. I believe from other posts on this forum and reading the tutorials that this welder's minimum of 30 amps will be OK but maybe marginal. Would I be better looking for something with a lower setting? A couple of supplementaries: What do the Clarke suffixes mean - EN TE etc? What is it that limits the low current capability on a welder? Naively it would seem to be simple to reduce the minimum current offered but, presumably, this is not so?
