I run a university welding shop and found a bird's nest, near the rollers, that had changed color but not burnt out or melted . now the millermatic 251 is no longer driving wire. the drive wheels are not moving. and thus no wire coming out. electrics are working and running relays, gas control is working fine. not really sure where the problem is. could the motor be burned out? i am really not sure what the problem is, and would appreciate any help.
thanks
