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.
Do not place the welding power source near combusti-
ble gases, otherwise, such gases may catch fire from a
spark of electricity inside the welding power source as
it is electric equipment.
(3) Do not bring the hot base metal near combustible
materials immediately after welding.
(4) When welding a ceiling, floor or wall, remove all flam-
mables including ones located in hidden places.
(5) Wire the cables correctly and connect them tightly.
Insulate the connected parts surely so that no exposed
conductive part touches the cases or housings. (Poor
cable connection or incomplete current path on the
base metal side, such as steel, if any, can cause fire
due to the heat generated by energization.)
(6) Connect the base metal cable as close to the welding
position as possible. (If not, unexpected current path
may be created, which can cause fire due to the heat
generated by energization.)

CAUTIONS
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 manipu-
lator 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 performance or
use a protective mask designed for welding operation.
(3) When welding or monitoring welding wear protective
closes 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.
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.
OMCTT5639E09
(3) Read the instruction manual of the gas regulator prior
to using it, 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.
Rotating parts
Rotating parts can cause injury.
(1) Keep away from rotating parts such as cooling fans,
feed roller of the wire feeder, or hand, finger(s) hair or
part of your clothes may be caught by the parts result-
ing 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 main-
tenance 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) Wire extends out from the end of the welding torch and
may stick into the eye, face or body.
(2) 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 may stick into your eye, face or
body.
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 pre-
vent such 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 accumu-
lated dust or dirt.
(3) When spatters or iron particles get into the welding
power source, turn off the power switches of the weld-
ing power source and power distribution box, and then
blow out.
