Regular Inspection Items
(You can add inspection items to the following items according to the actual situations.)
1. Remove dust from inside the welder.
Remove the top plate and side plates of the welder. Use dry compressed air to blow off the
spatters and dust from inside the welder. Then, remove the dirt and unexpected objects from
inside the welder.
Note
Heavy dust on the radiator affects cooling and may easily cause over-temperature protection.

Remove the top plate and side plates of the welder. Check for signs of peculiar smells,
discoloration, or damages caused by excessive heat. Check whether the connections are
loose.
3. Check the power cables and gas tube.

carefully and regularly resolve fastening issues.
