If there is no output from cooler receptacle RC2 and no high frequency, reset circuit breaker CB1.
What to do if my Miller Syncrowave 250 DX's coolant system does not work?
If the coolant system isn't working, be sure the input power cord is plugged into an energized receptacle. Check the line fuses or circuit breaker, and replace or reset if necessary. The motor may have overheated; the unit will start running when the motor has cooled.
What to do if there is decreased or no coolant flow in my Miller Syncrowave 250 DX?
If you notice decreased or no coolant flow, add coolant. Check for clogged hoses or the coolant filter. Disconnect the pump and check for a sheared coupling; replace the coupling if necessary.
What to do if there is no weld output and the Miller Syncrowave 250 DX unit is completely inoperative?
If there is no weld output and the unit is completely inoperative, place the line disconnect switch in the On position. Also, check and replace the line fuse(s) if necessary. Ensure that there are proper input power connections and check for the correct jumper link position.
What to do if the Miller Welding System has no weld output but the unit is on?
If the unit is on but there's no weld output, and if you're using remote control, place the Output control in the Remote 14 position and ensure the remote control is connected to the Remote 14 receptacle. If a remote is not being used, put the Output control in the On position. Check, repair, or replace the remote control if necessary.
How to troubleshoot erratic or improper weld output on my Miller Welding System?
To troubleshoot erratic or improper weld output, use the correct size and type of weld cable. Clean and tighten all weld connections. Check the position of the Output Selector control. If using remote control, check the position of the Amperage Adjustment control.

What does it mean when my Miller Syncrowave 250 DX indicates an SCR overcurrent or undercurrent condition?
If an SCR overcurrent or undercurrent condition has occurred, turn the power off and back on to correct the condition.
What does it mean if the fan is not operating on my Miller Welding System?
If the fan is not operating, it may be because the unit is equipped with Fan-On-Demand, meaning the fans run only when necessary. The unit is also equipped with circuitry to protect against overheating.
What causes wandering arc and poor control of direction of arc in Miller Welding System?
If you're experiencing a wandering arc and poor control of the arc's direction, reduce the gas flow rate. Select the proper size tungsten and properly prepare the tungsten.
