hi all, i'm back again to pick some brains! just went to use my 180 monomig and she doesnt want to do anything . as i pull the eurotorch trigger it just give a delayed action relay operation sound and then nothing. i have power at the main imput connector . power up to the multi connector that gives the various levels of amperage ie 1-6 but no gas valve operation or wire feed operation. any ideas please.regards, stanman
