2 Important Safety Items

Cutting power source
Observe the following instructions to
prevent the hazard.
(1)Never use the cutting power source for other than
cutting purpose. (e.g. Never attempt to use the
cutting 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 air, storage of cut 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 cutting work area.
(5)Pacemaker wearers should consult their doctor
before going near arc cutting. Magnetic fields can
affect pacemakers.
(6)Only educated and/or skilled persons who well
understand this cutting 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 cutting 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 cutting 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.
WARNING
(10)Perform periodic checks without fail and repair or
replace any damaged parts before using the power
source.
Ventilation and protective equipment
(1)When conducting cutting 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
regulation, rules on preventing suffocation or etc.) or
wear protective breathing gear.
(2)To prevent dust injury or poisoning by the fume
generated during cutting, 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 cutting 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 cutting at a site where degreasing,
cleaning or spraying is performed. Conducting
cutting near the area where any of these types of
work is performed can generate toxic gases.
(5)When cutting a coated steel plate, provide sufficient
ventilation or wear protective breathing gear.
(Cutting of coated steel plates generates toxic fume
and gas.)
Against fire, 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 cutting near combustible gases.
(3)Do not bring the hot base metal near combustible
materials immediately after cutting.
(4)When cutting 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 cutting part.
(7)Do not CUT a sealed tank or a pipe that contains a
gas.
(8)Keep a fire extinguisher near the cutting site for an
emergency.
