8.3 Periodical Inspection

This section explains the periodical inspection of the welding power source. Check the items in the table
below every three (3) to six (6) months.

• Before performing maintenance and inspection, read the instructions in "8.1

Precautions for Maintenance and Inspection" and "8.2

Daily Inspection".

Daily Inspection

Refer to the description for the same item in "8.2 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 the dirt inside. If there
is heavy dirt, blow the fin and coils of heat sink directly with compressed air to
remove dust inside.
