miller shopmaster 300 only maximum weld output in cv

Hi guys I have a miller shopmaster 300 and in CC the voltage/current settings work just fine from the front panel or from a foot pedal when tig welding but when I switch to CV for my wire feeder it is stuck at max voltage/current no matter what the knob is set at.

I have took the side panels off and looked for anything obvious but all looks good any help you guys could give me would be great .............. Thanks

I think that is a fix best left to a welder repair shop unfortunately.

There must be something I could try ... I just don't have extra money to take it to the shop not to mention the the closest welding repair shop is two and a half hours away.

Might ask around over at the MillerWelds forum.

Those guys know these machines like the back of their hand.

Good luck,

You can't post?
I'm guessing you registered?
I'm sure all the help you need is right over there.
Give it another try.

Yeah no problem.
There's a guy over there by the username of Cruiser, He's a expert welder technician.
Might ask him a question or two.
Good Luck,
