Gas Leak, Help, Please

[mignoramous]

Hi, I'm not sure if you are the guys to help me, but here goes: I've got a little Millermatic 135 with a factory torch. I've noticed the shield gas leaks anytime the machine is plugged in. This occurs whether the power switch on the front of the machine is turned on or off. It does not leak when the gas cylinder is opened and the machine is unplugged. Anyone have any ideas? Thanks in advance.

Okay, figure it must be a problem with the solenoid. But now I've noticed that my poor mig will buzz as soon as it is plugged in, with the power switch turned off! Yikes, I think this calls for a trip to the repair shop.
