8.2 Daily Inspection
This section explains the daily inspection of the welding power source. Perform daily inspection for the following items
in the table.
The front and rear panels and the fan of the welding power source is made from polycarbonate resin. To prevent from
electric shock or fire caused by the damage on polycarbonate resin, ensure to follow the instructions below.
CAUTION
•
The welding JOB (electronic data) stored by this function are susceptible to occurrence
of static electricity, impact, repair, etc., and there is a possibility that the stored
contents may be changed or lost. Important information should also be stored as
printed document.
Please note that OTC will not be liable for any alteration or loss of electronic
information.
•
When cleaning the welding power source, do not expose the cooling fan directly to
compressed air.
Otherwise powder dust may get inside the cooling fan. Also the cooling fan may rotate
at high speed due to compressed air, resulting in wearing of the bearing.
•
When using a vacuum cleaner to remove powder dust accumulating on the welding
power source, do not vacuum between the rotating part of cooling fan and the main
body.
Otherwise lubricant of the bearing of cooling fan may also be removed, resulting in
failure or shorter service life of the cooling fan.
•
Before performing daily inspection, refer to " 8.1
Precautions for Maintenance and
•
If there is dirt on plastic parts, soak a soft cloth in water, alcohol or neutral detergent,
wring it well and wipe off the dirt.
Do not use organic detergent or chemical agent. Doing so may cause crack (breaking)
and degrade the strength.
•
If there is any abnormality in the plastic parts such as front and rear panels,
immediately stop the use and contact your dealer.
Daily inspection item
Content
Status of the grounding cable
•
Check that the grounding terminal on the back of the welding power source is securely
grounded. (If it is not grounded, electric shock/failure/malfunction may occur.)
Status of cables
(Primary power cable for facility side, cables
for base metal side/torch side, torch cable,
voltage detection cable, etc.)
•
Check that there is no abnormal heat generation in cable connections.
•
Check that cable connections are not loose.
•
Check that cables are not cut or damaged.
Appearance of the welding power source
•
Check that there is no abnormality such as crack in plastic parts of the welding power
source.
Noise/vibration/odor generated from the
welding power source
•
Check that there is no sound of metal, abnormal vibration or burnt odor inside the welding
power source.
Status of the cooling fan
•
Check that the cooling fan smoothly rotates when the power switch is turned on. (There
should not be sound of metal, abnormal vibration or burnt odor.)
While the cooling fan is rotating, air is ventilated from the slits on the front and rear of the
welding power source.
Status of the operation panel/torch switch
•
Check that the keys on the operation panel and the torch switch work normally.
Status of the primary power voltage for
facility side
•
Check that there is not large fluctuation in the primary power voltage.
