Hello metprimate, it sounds likely that you have a problem with the trigger switch on the welding gun on the whip, to verify this you can disconnect the gun whip from the feeder(unplug the din plug or whatever type of connection that is connecting the whip to the feeder) and then turn the power back on to the feeder, if it doesn't try to feed wire anymore, then there is a short in the wiring in the whip or possibly the switch on the gun has something jamming it in the on position. If the feeder still tries to feed wire with the gun completely disconnected then there is likely a stuck relay or something else going on inside. Depending on your electrical prowess you might try to figure this out on your own or else it is time to take it to a service technician to be repaired. Hope this helps. Regards, aevald
