•
Maintenance of the arc welding equipment
Close and fix all doors and covers of the welding power source.
•
Welding cables
Do not use an unnecessarily long cable.
Place a base metal cable and a torch side cable as closely as possible.
•
Equipotential bonding
Bonding of all metallic objects in the surrounding area should be considered.
•
Earthing of the workpiece
The connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some
countries where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected
according to national regulations.
•
Screening and shielding
It is selective screening and shielding of other cables and equipment in the surrounding area.
3.3 Transportation Procedure
This section explains the procedure for transportation of the welding power source.
•
Do not touch the input and output terminals and the internal live electrical parts of the
welding power source.
It may cause electric shock.
•
Shut off the input power with the disconnect switch all turned off even the distance of
transportation is short.
If work is performed while the input power is on, electric shock may occur.
CAUTION
•
During transportation, be careful not to get the hand, leg or other body part caught
between the welding power source and floor.
•
Do not apply strong shock to the welding power source when placing it on the floor.
It may cause damage to the welding power source.
Since large current abruptly flows inside the welding power source during welding, other
machine near the welding power source may be failed due to electromagnetic noise.
Follow the instructions below:
•
Do not ground the welding power source commonly with other machines.
•
Close and fix all doors and covers of the welding power source.
•
Do not use an unnecessarily long cable.
•
Place a base metal cable and a torch side cable as closely as possible.
In the event of electromagnetic problems, follow the instructions below:
•
Change the installation place of the welding power source.
•
Keep the machines which may be affected away as far from the welding power source,
cables, and welding site as possible.
•
Add a noise filter to the input cables.
