Welding torch
•
Confirm that there is no deterioration, damage or other abnormality in
consumable parts of the welding torch.
Cleaning inside the welding power
source
•
Blow with dry compressed air from the front slit (ventilation hole) to the back side
to remove dust inside the welding power source.
Dust accumulating on the heat sink of transistor and rectifier may prevent heat
radiation, adversely affecting the transistor. Also, accumulation of dusts
between the winding of transducer could deteriorate insulation.

source
(When an abnormal temperature error
code is displayed)
•
Dust accumulating on the fin or winding of heat sink can cause insufficient heat
radiation.
Remove the left side panel and fan frame and check the the dirt inside. If there
is heavy dirt, blow the fin and coils of heat sink directly with compressed air to
remove dust inside.
