hi, can anyone help me? ive never used a mig before, my mate gave me a snap on 2135 the other day and told me the torch was arcking out, ive been told it might be the fibres in the tip, could it be anything else? also there is a dial on the front of the unit with 2 circles and a line through them, i presume this is the wire feed speed, but it just spins round easily as if something is broken and it doesnt seem to do anything when you turn it, would it be possible to get hold of a new switch or something? any ideas, many thanks, mac.
