2.1
Installation Site and Welding Source Environment
The welding source can be used under the following environmental conditions:
• Dry, indoor and at least 30 cm from the wall or peripheral devices
• Free from direct sunlight, wind, and rain
• Ambient temperature of 0 to 40
°
C
• Altitude less than 1000 m
• Free from direct splash of welding spatter or metallic fine powder at grinding
2.2
Precautions on Grounding
1.
Be sure to perform secure grounding work (ground resistance must be 100
Ω
or less)
on the welding source so as not to charge its case or lead to unstable operation.
2.
Connect a grounding cable of 14 mm
2
or thicker to the terminal marked "GROUND" or
"EARTH".
3.
Be sure to ground the base metal (ground resistance must be 100
Ω
or less) as well
when or any other non-conductive material is placed under the base metal.
• The welding source can be moved easily by using the caster. After
installation, use the stopper to fix the welding source before starting
operations.
For precautions on transporting, see " 2.9 Precautions on Transporting ".
• Be sure to turn OFF the main switch of the switchboard before perform-
ing the grounding work.
• If the welding source is used with rated input voltage: 480 V(6N0), the
ground resistance must be 100
Ω
or less. Grounding must be performed
by authorized or certified personnel.
