3.2 Installation Environment
This section explains the installation environment of the welding power source.
3.2.1
Installation environment
•
Location with no combustible materials or flammable gas
If combustible materials cannot be removed, cover them with noncombustible covers.
•
Location with no scattering of organic solvent, chemicals, cutting oil, and composition oil or atmosphere containing
the above
Such materials cause crack (breaking) and deterioration in the plastic part.
•
Location with no exposure to direct sunlight or rain
•
Robust and flat floor surface such as concrete pavement
Assure sufficient floor face strength to ensure that the weight of welding power source can withstand.
Face the surface with the eyebolt on upside to prevent from falling.
•
Location with an ambient temperature of -10 to 40 °C
•
No condensation at location with an ambient humidity of 50 % or lower (ambient temperature of 40 °C), and 90 % or
lower (ambient temperature of 20 °C)
•
Location with an altitude of less than 1000 m
•
Location with an incline of 10° or less
•
Location with no metallic foreign body such as spatter entering the welding power source
•
Installation distance of 30 cm or more between the welding power source and the wall or other welding power source
Ensure not to block the ventilation hole.
•
Location with no wind on the arc section
Install a wind shield to protect arc from wind.
3.2.2
Electromagnetic interference
To prevent electromagnetic troubles, read the following. Also, if electromagnetic troubles occur, check the following again.
Before installing arc welding equipment the user shall make an assessment of potential electromagnetic problems in the
surrounding area. The following shall be taken into account:
•
Other supply cables, control cables, signaling and telephone cables, above, below and adjacent to the arc welding
equipment;
•
Radio and television transmitters and receivers;
•
Computer and other control equipment;
•
Safety critical equipment, for example guarding of industrial equipment;
•
The health of the people around, for example the use of pacemakers and hearing aids;
•
Equipment used for calibration or measurement;
•
The user shall ensure that other equipment being used in the environment is compatible;
•
The time of day that welding or other activities are to be carried out;
Methods of reducing EMC:
•
Public supply system
Add a noise filter to the input cables.
•
For prevention from fire or damage to the welding power source, be sure to install in a
location that satisfies the following environment:
