Reply:It sounds as if your trigger switch isn't working properly. Open the side of the machine and make sure that the gun trigger terminals are connected to the machine. If they are connected, I'd then pull the gun apart and test the switch with an ohm meter.- Paulhttp://all-a-cart.comWelding Cart Kits and accessories
