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.
• Do not touch the input and output terminals and the internal live electrical parts of the
welding power source.
• Have a qualified electrical engineer ground the case of the welding power source and
base metal or jig electrically connected in accordance with local regulation.
• Before starting maintenance and inspection, make sure to cut the input power with the
disconnect switch in the box connected with the welding power source and wait three
minutes or more.
The capacitors may be still charged even after the input power is cut. Make sure that
there is no charged voltage before starting the work.
• Wear dry insulating gloves for protection. Do not use damaged or wet gloves.
• Tighten all cable connections and insulate them.
• Do not wrap cables around the body.
• Perform periodical maintenance and repair damaged parts if any before use.
• Turn off POWER switch of all the related equipment when not in use.
• Periodically blow the parts of welding power source with dry compressed air to remove
dust.
Powder dust accumulating inside may cause insulation deterioration, resulting in
electric shock or fire.
• Do not use a cable with insufficient capacity, serious damage or cable without
grounding.
CAUTION
• When the power switch is tripped, never turn it on again and contact your dealer.
• Do not apply external force or shock to the front panel, rear panel and fan.
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.
