1.2.3
Precautions for handling of plastic parts
Front panel, rear panel and fan of the welding power source is made from polycarbonate resin. To prevent from electric
shock or fire caused by the damage on polycarbonate resin, ensure to follow the instructions below.
1.2.4
Precautions for disassembling and modifying the welding power source
To prevent electrical shock, fire, injury from malfunction and error in the welding power source, ensure to follow the
precautions below:
1.2.5
Precautions for air discharge and use of respiratory protective equipment
To prevent suffocation or gas poisoning in the welding operation, ensure to follow the instructions below:
To prevent any health damage due to poisonous gas or particle substances (fume) emitted in the welding operation, ensure
to follow the instructions below:
• Do not apply external force or shock to the front and rear panels.
Otherwise, damage and malfunction may occur.
• If there is dirt on plastic parts, soak a soft cloth in water, alcohol or neutral detergent,
wring it well and wipe off the dirt.
Do not use organic detergent or chemical agent. Doing so may cause crack (breaking)
and degrade the strength.
• If there is any abnormality in the plastic parts such as front panel, rear panel and fan,
immediately stop the use and contact your dealer.
• Do not use the welding power source at location in which organic solvent, chemicals,
cutting oil and composition oil adhere or atmosphere containing the above.
Doing so may cause crack (breaking) and deterioration in the plastic part.
• Do not disassemble/modify the welding power source.
Disassembling/modifying by customer is out of the warranty scope.
• When welding is required in tank, boiler, reaction tower, or hold of a ship, closed space,
or any other places of poor ventilation, ensure to provide ventilation equipment.
• Gas of larger gravity than that of oxygen, such as carbon dioxide gas or argon gas,
retains at the bottom part.
To prevent anoxia due to the retention gas, provide ventilation equipment.
• When it is difficult to provide ventilation equipment or the ventilation equipment does
not give sufficient performance, ensure to use respiratory protective equipment.
For preventive measure from falling due to anoxia, apply lifelines such as a safety belt.
• For the welding operation in a narrow space, perform the operation with the trained
supervisor.
• Periodically inspect the ventilation equipment to ensure correct and proper
performance of ventilation.
