What to do if my Miller Electric Welding System has erratic arc with excessive spatter?
If you observe an erratic arc accompanied by excessive spatter, ensure that you are using dry, properly stored electrodes. Shorten the arc length and reduce the amperage setting.
How to fix erratic weld current on my Miller Electric Welding System?
To address erratic weld current, clean and tighten all weld cable connections.
What to do if my Miller Electric Welding System has no weld output and the fan doesn't run?
First, ensure that the line disconnect switch is in the On position. Then, check the line fuses and replace them if they are open. Reset the breakers if necessary.
How to fix noise and vibration from shunt block in Miller Electric Welding System?
To resolve noise and vibration issues originating from the shunt block, lubricate the shunt block and/or tighten the adjustment screws.
What to do if the fan does not run on my Miller Electric Welding System, but weld output is okay?
Ensure that nothing is obstructing the fan's movement. If the fan still does not run freely, consider replacing the fan motor.
