10.2 Periodic check
●
To
secure physical safety, make sure that a qualified person or a person
who is familiar with the welding machine takes care of a regular check.
●
As for the inside check, make sure to conduct it at least 5 minutes after
turning the power off in consideration of electric discharge from a capacitor.
To prevent the electrostatic destruction of semiconductor parts and the printed
circuit board, observe the following.
Allow static electricity to escape by, for example, touching the metal parts of the case
with your hand before touching the equipment, the conductor of wire and/or the
printed circuit board.
Notice
About cleaning of plastic parts
●
Plastic parts may be melted or deformed when they are subjected to organic solvent (benzin, toluene,
kerosene, gasoline, etc.).
●
When cleaning them, soak a soft cloth with a small amount of water or diluted mild detergent for home
use, and wring it and use for wiping those parts.
●
Daily checks are not enough to keep the proper performance of this product for a long time.
●
Perform the periodic check without fail. It is important to keep the proper performance of this product for a
long time.
●
In the periodic check, check the product thoroughly including checking and cleaning of the inside
of this product.

Check item Guideline
Removal of inside dust
●
Remove the top panel before cleaning.
●
Blow off internally-accumulated dirt and dust by compressed air without
moisture included (dry air).
Overall check
Remove the top panel and check the followings and other items that are not covered
by the daily check intensively.
•
The presence of odor, discoloration, and traces of heat generation
•
Loose connections
•
Additional fastening
Cables and hoses
Regarding the grounding wire (for this product, base material, etc.), input and output
cables, cables for the torch switch, remote control unit, etc., and hoses (for gases,
and for water supply and drainage when using the water-cooling torch), check those
items that are not covered by the daily check (See page 12-1) intensively.
Inspection and
maintenance of
consumable parts
When conducting inspection or maintenance, treat the cooling fan and
electrolytic capacitor as consumable parts as they have a given electrical and
mechanical life respectively.
For example, when they are used under the rated specifications, the life of the
cooling fan is about 10,000 hours, and that of the electrolytic capacitor is about
8,000 hours. Their actual duration depends on how those items are used by
customers.
