    mig welder problem is electrical not mechancial

    Check for crud buildup in the feed motor or the feed sprockets. The main power supply board may have failed too. If you're not getting the proper voltage into the rheostat, it will never give the voltage you need for higher speeds. Some units need 12 volts, some 50 & some 120 volts.



    What is the make & model of the unit?

    You quite possibly have a clogged liner on your stinger.

I have an 85 corvette. the problem is the air conditioning. I have it on high speed but the air blows out very little like if its on low speed. and the compressor and evaporator is new so what could it be...


If your car has a cabin filter (check owners/service manual) it may be clogged.

You may also have a vacuum leak under the dash causing the vent flaps to not open all the way.

Heter blower is 50 - 50 to work or not from start up. 'if' it comes on it works for minutes, it will slow down as engine speed increases, back to full when clutch dipped to change gear, then slows down...


Items to check with blower motor:
First there is NO correlation to engine speed and blower motor.
Blower motor may be dying, Blower resistors are defective, on/off switch.
If there is no voltage to the reverse switch, then you have to back probe that wire and see where the open is.
The answer to your question yes there is a common connection. Probably at the fuse box. Like I said earlier you have to back probe wire to reverse switch and find out where it is open. Good luck

Wire Speed Increases when voltage increases


What is it doing? stabbing the wire into the work? The voltage is too low for the speed of the wire feed.. Turn up your voltage and slow down the wire. then increase your wire according to the speed of travel of weld. That is an awesome machine but it is still up to you to get the settings dialed in. Good Luck, Ned.
