7. TRANSPORT AND INSTALLATION (continued)
CAUTION
To prevent electromagnetic troubles, read the following. Should
electromagnetic troubles occur, check the following again.
Since large current abruptly changing flows through the welding machine to base metal during
welding, other machines near the welding machine may be troubled due to electromagnetic
noise.
●
Do not ground the base metal and welding power source commonly with other machines.
●
Tightly close and fix all doors and covers of the welding machine.
●
Do not use an unnecessary long grounding cable.
●
Extend the torch cable and the base metal cable as straight as possible.
Countermeasures on occurrence of electromagnetic troubles are as follows.
●
Change the installation place of the welding machine.
●
Keep the machines which may be affected away from the welding machine, the cables and
the welding site as far as possible.
●
Add a noise filter to the input cables.
●
Install input cables in the grounded metallic conduit.
●
Provide electromagnetic shield to the whole welding places.
If electromagnetic troubles can not be solved after trying the above measures, consult your
nearest DAIHEN dealer.
ＨＦ
CAUTION
●
Use a wheel stopper after installation of the welding power source.
●
Do not place heavy objects on the welding power source.
●
Do not block the vent holes of the machine.
●
Fix the gas cylinder to the stand for gas cylinder only (see fig. 1).
INSTALLATION PLACE
Observe the following when selecting an installation place.
・
・
・
・
・
Be sure to keep the machine more than 1ft. (30cm) away from the wall or other welding power sources.
(see fig. 2).
Do not install in the place where metal material such as spatter enters the equipment.
Do not install in a place subject to direct sunlight, rain, excessive moisture, oil steam, or corrosive gas.
Install the equipment in the place where the altitude is 3300ft.(1000 m) below, the ambient temperature
is between 14F
°
(-10C
°
) and 104F
°
(40C
°
), and the relative humidity is 50% at 104 F
°
(40C
°
) or
90% at 68 F
°
(20C
°
).
Use a wind shield to protect the arc from wind, otherwise welding defects may occur (see fig. 3).
