2 Safety precautions
Welding power source
Observe the following instructions to
prevent the hazard.
(1)Never use the welding power source for other than
welding purpose. (e.g. Never attempt to use the
welding power source for pipe thawing.)
(2)It is very important to comply with all instructions,
safety warnings, cautions and notes mentioned.
Failure to do so can result in serious injury or even
death.
(3)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 instructions and national, state and
local codes and regulations.
(4)Prevent any unauthorized personnel to enter in
and around the welding work area.
(5)Pacemaker wearers should consult their doctor
before going near arc welding. Magnetic fields can
affect pacemakers.
(6)Only educated and/or skilled persons who well
understand this welding power source should
install, operate, maintain and repair the unit.
(7)Only educated and/or skilled persons who well
understand the operating instructions of the unit
and are capable of safe handling should perform
operation of the unit.
Against electric shock
Observe the following instructions to
prevent the hazard.
(1)Do not touch live parts.
(2)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.
(3)Before installation or maintenance work, turn off
power at the power box, wait it for at least five
minutes to discharge capacitors. Significant 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.
(4)Do not use undersized, worn, damaged or bare
wired cables.
(5)Connect cables firm and insulate connection parts.
(6)Keep all cases, panels and covers securely in
place.
(7)Do not handle the welding power source with torn
or wet gloves.
(8)Wear safety harness in case of working above floor
level.
(9)Turn off all equipment when not in use.
(10)Perform periodic checks without fail and repair or
replace any damaged parts before using the power
source.
Ventilation and protective equipment
Oxygen deficit, fume and gas
generated during welding can
be hazardous.
(1)When conducting welding in the bottom of the tank,
boiler or hold as well as legally-defined sites, use a
local exhauster specified by the applicable laws
and regulations (occupational safety and health
regulation, rules on preventing suffocation or etc.)
or wear protective breathing gear.
(2)To prevent dust injury or poisoning by the fume
generated during welding, use a local exhauster
specified by the applicable law (occupational safety
and health regulation, rules on preventing injury by
inhaled dust or etc.), or wear protective breathing
gear.
(3)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.
(4)Do not conduct welding at a site where
degreasing, cleaning or spraying is performed.
Conducting welding near the area where any of
these types of work is performed can generate toxic
gases.
(5)When welding a coated steel plate, provide
sufficient ventilation or wear protective breathing
gear. (Welding of coated steel plates generates
toxic fume and gas.)
Against fire, explosion or blowout
Observe the following cautions to
prevent fires explosion or
blowout.
(1)Remove any combustible materials at and near the
work site to prevent them from being exposed to
the spatter. If they cannot be relocated, cover them
with a fireproofing cover.
(2)Do not conduct welding near combustible gases.
(3)Do not bring the hot base metal near combustible
materials immediately after welding.
(4)When welding a ceiling, floor or wall, remove all
flammables including ones located in hidden
places.
(5)Properly connect cables and insulate connected
parts. Improper cable connections or touching of
cables to any electric current passage of the base
metal, such as steel beam, can cause fire.
(6)Connect the base metal cable at a section closest
to the welding part.
(7)Do not weld a sealed tank or a pipe that contains a
gas.
(8)Keep a fire extinguisher near the welding site for
an emergency.

III
Installing shielding (curtain etc.)
Arc flash, flying spatter, slugs, and
noise generated during welding can
damage your eyes, skin and hearing.
(1)Install a protective curtain around the welding
manipulator site to prevent the arc flash from
entering the eyes of people in the surrounding area.
(2)When welding or monitoring welding, wear safety
glasses with sufficient light blocking structure or
use a protective mask designed for welding
operation.
(3)When welding or monitoring welding wear protective
clothing designed for welding operation, such as
leather gloves, leg cover and leather apron, and also
wear long-sleeve shirts.
(4)Be sure to wear noise-proof protective equipment if
the noise level is high.
(5)The larger the welding current is, or in case of AC
TIG or MIXTIG welding, the larger the AC frequency
is, the larger the arc sound becomes.
Gas cylinder and gas flow regulator
Overturn of gas cylinder and
blowout of gas flow regulator can
cause injury.
(1)The gas cylinder must be handled properly according
to the applicable law and in-house standards.
(2)Use the gas flow regulator that is supplied or recom-
mended by our company.
(3)Read the instruction manual of the gas regulator prior
to using it, and observe the cautions in the manual.
(4)Secure the gas cylinder to a dedicated gas cylinder
stand.
(5)Do not expose the gas cylinder to high temperature.
(6)When opening the valve of the gas cylinder, do not
bring your face close to the discharge outlet.
(7)When the gas cylinder is not used, be sure to install a
protective cap.
(8)Do not hang the welding torch on the gas cylinder, or
touch the gas cylinder with the electrode.
(9)Do not attempt to disassemble or repair the gas
regulator. Such works require special knowledge.
Rotating parts
Rotating parts can cause injury.
(1)Keep away from rotating parts such as cooling fans，
and feed roller of the wire feeder, or hand, finger(s)，
hair or part of your clothes may be caught by the
parts resulting in injury.
(2)Keep all covers, panels and cases closed when
using the product.
(3)Maintenance work and repair should be perform only
by educated and/or skilled persons who thoroughly
understand welding machines. While
performing maintenance work or repair work, provide
fence or the like around the welding machine so that
unauthorized person can not come close carelessly.
Welding wire
Welding wire, especially wire tip part
can cause injury.
(1)Do not perform inching operation or pull the torch
switch with your eyes, face or body close to the end
of the welding torch - wire extends out from the end
of the welding torch and may stick into the eye,
face or body.
(2)In case of using a torch cable with the resin liner,
straighten the torch cable and reduce the preset
feed amount (current) to a half or less before
applying the wire inching.
(3)Performing wire inching while torch cable has been
bent extremely can cause the wire to pierce the
resin liner and cable. Make sure to replace any
damaged liner or cable with a new one, or
damaged liner/wire can cause gas leak or dielectric
degradation.
. Against insulation deterioration
Insulation deterioration can cause fire
of welding power source.
(1)Keep enough distance from welding power source
when performing welding or grinding work so as to
prevent spatters or iron particles from getting
into the power source.
(2)Perform check and maintenance work periodically
so as to prevent insulation deterioration due to
accumulated dust or dirt.
(3)When spatters or iron particles get into the welding
power source, turn off the power switches of the
welding power source and power distribution box,
and then blow out.
(4)Make sure to replace any damaged liner or cable
with a new one as use of damaged liner/cable may
cause gas leak or dielectric degradation.
(5)In order to avoid dust and dirt to be collected inside
of the power source, make sure not to leave the
panel and bolts (including eyebolts) open and
removed.
