I suspect this might be largely down to individual preference but I'm curious to know what length of leads you find most useful. My stock leads are about 3m each for the holder and return and I've run into a couple of occasions where I've had to balance the welder precariously on something to give me sufficient slack on the cables. I'm thinking of making up a couple of DINSE extensions I can plug in when I need a bit more reach. Obviously I don't want to make them longer than necessary due to volt drop and cost. I also don't want to make them too uncontrollable either. The standard leads are 25mm2 on a 200A machine. I'm thinking perhaps 35mm2 H01N2 cable for the extensions, but not sure on the length. Anybody done this and what did you use?
