What to do if my Miller Syncrowave 351 Welding System's fan is not operating?
Check for and remove any obstructions that may be blocking the fan's movement. If the fan still doesn't work, have a Factory Authorized Service Agent check the fan motor.
What to do if Remote 14 receptacle RC1 is not working properly on my Miller Welding System?
Be sure the Amperage control switch and the Output switch are in the Remote 14 position.
What to do if there's no output from duplex receptacle RC2 and no high frequency on my Miller Welding System?
Reset the circuit breaker CB1.
Why is there no weld output from my Miller Syncrowave 351 Welding System, but the unit is on?
Several factors could cause this. If you're using a remote control, ensure the Output switch is in the Remote 14 position and the remote is properly connected. If not using a remote, set the Output switch to the On position. The unit may have overheated; allow it to cool with the fans on. If these steps don't resolve the issue, a Factory Authorized Service Agent should inspect the control board PC1.
What to do if my Miller Syncrowave 351 Welding System has erratic weld output?
First, ensure you are using the correct size and type of weld cable. Then, clean and tighten all weld connections. Verify the position of the Output Selector switch and, if using a remote control, check the Amperage Adjustment control position.
How to troubleshoot lack of high frequency and difficulty starting GTAW arc in Miller Syncrowave 351?
To address this, try the following: reset circuit breaker CB1, select the proper size tungsten, check the High Frequency Intensity control setting, ensure the electrode holder cable isn't near grounded metal, inspect cables and the torch for damage (repair or replace if needed), check the spark gaps, and reduce the gas flow rate.
How to fix tungsten electrode oxidizing in Miller Syncrowave 351 Welding System?
To prevent tungsten oxidation, shield the weld zone from drafts, increase postflow time, check and tighten all gas fittings, properly prepare the tungsten, and check for water in the torch, repairing it if necessary.
What to do if my Miller Syncrowave 351 provides only maximum or minimum weld output?
Check that the Amperage switch is in the correct position. If the problem persists, have a Factory Authorized Service Agent inspect the hall device HD1, filter board PC2, and control board PC1.
What to do if my Miller Syncrowave 351 Welding System is completely inoperative and has no weld output?
