Why is the weld output erratic on my Miller AC Power Distribution?
If you experience erratic weld output with your Miller AC Power Distribution, use the correct size and type of weld cable. Clean and tighten all weld connections. Also, check to ensure proper input connections.
What to do if my Miller AC Power Distribution unit has no weld output and is inoperative?
If there is no weld output and the unit is completely inoperative, with the pilot light off, ensure the Power switch and line disconnect switch are in the On position. Also, check the line fuses and replace them if open, or reset the circuit breakers. Verify proper input connections.
What to do if Miller AC Power Distribution open-circuit voltage is normal but wire doesn't feed?
If the open-circuit voltage is normal, the pilot light is on, but the wire does not feed, consult the gun or wire feeder Owner’s Manual for troubleshooting guidance.
What to do if Miller AC Power Distribution has no open-circuit voltage but wire doesn't feed?
If there is no open-circuit voltage, the pilot light is on, and the wire does not feed, make sure the gun trigger connections are secure, and check the gun Owner’s Manual. Also, ensure the plug is securely inserted in Remote 14 receptacle RC3.
Why Miller AC Power Distribution has no open-circuit voltage but wire feeds?
If there is no open-circuit voltage, the pilot light is on, and the wire feeds, the thermostat may be open due to overheating. Allow the unit to cool down.
