Daily Inspection".
Each cables
(Primary power cable for facility side, cables
for base metal side/torch side, torch cable,
voltage detection cable, etc.)
Welding torch
•
Check that there is no deterioration, damage or other abnormality in consumable parts of
the welding torch. Abnormality in consumable parts can prevent smooth wire introduction.
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.
Cleaning inside the welding power 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 dirt inside. If there is heavy dirt,
blow the fin and coils of heat sink directly with compressed air to remove dust inside.
