What causes a lack of high frequency and difficulty starting GTAW arc with my Miller Welding System?
If you experience a lack of high frequency and difficulty starting a GTAW arc, reset circuit breaker CB1. Select the proper size tungsten. Ensure the torch cable is not close to any grounded metal. Check cables and torch for cracked insulation or bad connections and repair or replace them. Check the spark gaps.
What to do if my Miller Syncrowave 250 DX Welding System provides only maximum or minimum weld output?
If your unit provides only maximum or minimum weld output, ensure the Amperage control is in the proper position.
What should I do if my Miller Syncrowave 250 DX Welding System's tungsten electrode is oxidizing?
If the tungsten electrode is oxidizing and not remaining bright after welding, shield the weld zone from drafts. Increase the postflow time. Check and tighten all gas fittings. Properly prepare the tungsten. Also, check for water in the torch, and repair the torch if needed.
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 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.
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 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 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.
