2. Important Safety Items

The following instructions must be followed carefully in case of working near the robot performing arc welding operation.
WARNINGS
Welding power source
Observe the following instructions to
prevent the hazard.
This welding power source is designed and manufactured giving due consideration to safety of the product, however, it is very important to
comply with all instructions, safety warnings, cautions and notes mentioned in this operating instruction.
injury or even death.
Work of driving source at the input side, selecting work site, handling, storage and piping of high pressure gas, storage of welded products and
also disposal of waste should be performed according to the operating instruction and national, state and local codes and regulations.
Prevent any unauthorized personnel to enter in and around the welding work area.
Pacemaker wearers should consult their doctor before going near arc welding. Magnetic fields can affect pacemakers.
Only educated and/or skilled persons who well understand this welding power source should install, operate, maintain and repair the unit.
Never use filtering devices to cover vents of power source.
warranty.
Never use the welding power source for other than welding purpose.
(e.g. Never attempt to use the welding power source for pipe thawing.)
Against electric shock
Touching any live electrical parts can
cause fatal electric shocks or severe
burns.
Never touch live electrical parts.
Grounding of the case of the welding power and base metal or a jig electrically connected to the base metal must be performed by educated
and/or skilled persons.
Before installation or maintenance work, turn off power at the power box, wait it for at least five minutes to discharge capacitors.
voltage may exist on capacitors after turning off power at the power box so it is imperative to check to make sure that no charged voltage present
at capacitors before touching any parts.
Do not use undersized, worn, damaged or bare wired cables.
Connect cables completely and insulate connection parts.
Keep all cases, panels and covers securely in place.
Do not handle the welding power source with torn or wet gloves.
Wear safety harness in case of working above floor level.
Perform periodic checks without fail and repair or replace any damaged parts before using the power source.
Turn off all equipment when not in use.
In case of AC arc welding in a confined area or above floor level, check related national, state and local codes and
regulations for any special treatment and comply with it if any.
Ventilation and protective equipment
Oxygen deficit, fume and gas
generated during welding can be
hazardous.
To prevent gas poisoning and suffocation by the gas generated during welding, use a local exhauster specified by the applicable law, or wear
protective breathing gear.
To prevent dust injury or poisoning by the fume generated during welding, use a local exhauster specified by the applicable law, or wear
protective breathing gear.
When conducting welding in the bottom of the tank, boiler or hold, make sure to provide sufficient ventilation or wear protective breathing gear.
Gas heavier than air generated during welding, such as carbon dioxide gas or argon gas settles in the bottom if conducted in such area.
When conducting welding in a confined area, make sure to provide sufficient ventilation or wear protective breathing gear and have a trained
supervisor observe the workers.
Do not conduct welding at a site where degreasing, cleaning or spraying is performed.
types of work is performed can generate toxic gases.
When welding a coated steel plate, provide sufficient ventilation or wear protective breathing gear.
