TEST PROCEDURE
1.Disconnect the control cable amphenol plug from the welding power source and the wire feeder.
2.Using a multimeter, measure the resistance of the control cable wiring from the amphenol plug on the wire feeder end to the terminal connectors or amphenol plug on the welding power

source end. Refer to the Wiring Diagrams in Section G, Table F.2, and Figure F.3 for wire designations.
3.If the conductor resistance measures greater than 1.0 Ohm, the cable is faulty and should be replaced. If the resistance between conductors is less than 0.5 MOhm, the cable is faulty and should be replaced.
