What to do if my Cornwell Tools MMWMGS250 does not power up?
If your Cornwell Tools Welding System isn't powering up, there are several potential causes. First, ensure the unit is properly plugged in. If it is, check the input power circuit breaker and reset it if necessary. Lastly, the main power switch might be faulty and require replacement.
Why is the welding arc unstable with excessive spatter on my Cornwell Tools Welding System?
An unstable welding arc with excessive spatter on your Cornwell Tools Welding System can stem from several issues. Check that the correct contact tip is installed and that the torch liner is clear of obstructions, replacing it if necessary. Ensure you have a shielding gas supply connected and turned on. Also, make sure the MIG torch is correctly installed. Finally, verify that both the wire speed and voltage settings are appropriate by referring to the label inside the wire compartment door.
What to do if the protection indicator is on for my Cornwell Tools MMWMGS250?
If the protection indicator is illuminated on your Cornwell Tools Welding System, it could be due to a few reasons. The internal temperature may be too high; in this case, leave the power on and allow the fan to cool the unit. It could also be caused by input power voltage that's too high or too low; use a meter to check that the input voltage is within the acceptable range of 230V AC plus or minus 15%. A damaged cooling fan can also trigger the protection indicator, requiring you to replace the fan.
Why does the wire feed inconsistently on my Cornwell Tools Welding System?
Inconsistent wire feeding in your Cornwell Tools Welding System might be due to a plugged torch liner, which would require clearing or replacement. Another cause could be variations in the wire diameter on the spool, causing it to catch; try increasing the contact tip one size. Also, check the wire tension. Finally, the drive roll could be worn, which means that it should be replaced.
What to do if the wire drive motor doesn't turn on my Cornwell Tools MMWMGS250?
If the wire drive motor on your Cornwell Tools Welding System isn't turning, first ensure that the wire feed speed control is not set to zero; increase it if necessary. Also, the wire will only feed when the trigger is mashed. If these aren't the problem, the wire drive motor may be damaged and require replacement.
