Your previous messageI have a Thermal Dynamics PakMaster 100 XL Plus.When I bought it the plasma gun was missing. I hooked air and power to it and the fan come right on and about 5 seconds later you could hear a magnetic starter click on and air started blowing out the hose end where the gun goes. Just wondering if these machines will do this with the gun wires not attached. I think that this machine had a newer style thermal dynamic upgrade before and someone robbed the gun. Does anyone out there that could help me with this machine? I'm new to this forum Thanks
