What to do if Miller Electric OM-227 398D Welding Accessories have no wire feed at gun, but feeder is not operating?
If there's no wire feed at the gun and the feeder isn't operating, you can try the following: First, reset the circuit breaker in the feeder/control box. If that doesn't work, replace the trigger switch and test if it now operates correctly. Also, check the trigger switch wires for continuity.
What to do if Miller Electric OM-227 398D wire feeds erratically?
If the wire feeds erratically, check the conduit for wear and obstruction, replacing it if necessary. Also, verify the contact tip is the correct size and replace it if needed.
What to do if Miller Electric OM-227 398D have no wire feed at gun, but feeder is operating properly?
If there is no wire feed at the gun but the feeder is operating properly, reset the circuit breaker in the feeder/control box and check for a short in the motor leads. You can also check the potentiometer with a meter and replace it if necessary. Finally, check the motor and potentiometer wires for continuity.
Why does Miller Electric Welding Accessories arc vary and welding wire is kinked when feeding out gun?
If the arc varies and the welding wire is kinked when feeding out of the gun, place the Motor Torque switch in the low torque position if welding with .030 (0.88 mm) aluminum welding wire on an XR control box.
What to do if pressing gun trigger does not energize feeder in Miller Electric OM-227 398D Welding Accessories?
If pressing the gun trigger does not energize the feeder, make sure the plug from the gun control cable is securely inserted into the gun control receptacle on the feeder.
Why Miller Electric OM-227 398D wire feeds, but welding wire is not energized?
Clean and tighten all power connections. Check operation of welding power source.
Why Miller Electric OM-227 398D wire feeds one speed only?
If the wire feeds at only one speed, check the potentiometer with a meter and replace it if necessary. Also, check the continuity of the welding gun wire feed speed potentiometer and replace it if needed.
