Safety Precautions
OM1305066E26

(5) Provide measures against noise to the external equip-
ment, such as sequencer of the jig, proximity switch
and area sensor, if such equipment is affected by the
inverter noise from the robot or welding power unit.
For details of the measures, please refer to the operat-
ing instructions of the external equipment.
Ventilation and Protective Equipment
(1) Provide sufficient ventilation or wear breathing equip-
ment specified by the applicable law (occupational
safety and health regulation, ordinance on the preven-
tion of oxygen deficiency and the like).
(2) To prevent dust injury or poisoning by the fume gener-
ated during welding, use a local exhauster specified by
the applicable law (occupational safety and health reg-
ulation, rules on preventing injury by inhaled dust or
etc.) or wear a protective breathing gear. If a protective
breathing gear is used, it is recommended to use one
with an electric fan with high protection performance.
(3) When conducting welding in the bottom, such as tank,
boiler and the hold of a ship, use a local exhauster or
wear breathing equipment specified by the applicable
laws and regulations.
(4) When conducting welding in a confined area, make
sure to provide sufficient ventilation or wear breathing
equipment and have a trained supervisor observe the
workers.
(5) 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 per-
formed can generate toxic gases.
(6) When welding a coated steel plate, provide sufficient
ventilation or wear protective breathing gear. (Welding
of coated steel plates generates toxic fume and gas.)
(7) Never ventilates with oxygen. Refer to ANSI Z49.1(For
North America).
Against Fire, Explosion or Blowout
(1) Remove any flammable materials at and near the work
site to prevent exposure of such flammable materials
to the spatter. If they cannot be relocated, cover them
with a fireproofing cover.
(2) Do not conduct welding near flammable gases. Do not
place the electric equipment near flammable gases,
otherwise, such gases may catch fire from a spark of
electricity inside the electric equipment.
(3) Do not bring the hot base metal near flammable mate-
rials immediately after welding.
(4) When welding a ceiling, floor or wall, remove all flam-
mable including ones located in hidden places.
(5) Connect cables firm and insulate the 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 as close as possible to
the welding section.
(7) Do not weld a sealed tank or a pipe that contains gas.
(8) Keep a fire extinguisher near the welding site for an
emergency.
No Disassembling/Modification
(1) Contact Panasonic sales representatives for repair work.
(2) As for inspection of the inside the product if needed,
follow the instructions in the operating instructions.
Installing Shielding (Curtain etc.)
(1) When welding or monitoring welding operation, wear
safety glasses with sufficient light blocking structure or
use a protective mask designed for welding operation.
(2) When welding or monitoring welding operation, wear
protective clothing designed for welding operation,
such as leather gloves, leg cover and leather apron,
and also wear long-sleeve shirts.
(3) Install a protective curtain around the welding opera-
tion site to prevent exposure of eyes of people in the
surrounding area to the arc flash.
(4) Be sure to wear noise-proof protective equipment, such
as ear muffs and ear plugs, if the noise level is high.
Gas Cylinder and Gas Flow Regulator
(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 operating instructions of the gas regulator
prior to use, and observe the cautions described in it.
(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 in use, be sure to put the
protective cap back on.
(8) Do not hang the welding torch on the gas cylinder. Do
not allow the electrode to touch to the gas cylinder.
(9) Only the specified contractor should perform disas-
sembly or repair work on the gas flow regulator. Such
works require some expertise.
WARNING
Oxygen deficit, fume and gas generated
during welding can be hazardous.
Observe the following cautions to pre-
vent fires explosion or blowout.
Unauthorized disassembling or modifi-
cation can cause fire, electric shock or
breakdown.
CAUTION
Arc flash, flying spatter and slugs gener-
ated during welding can damage your
eyes, skin and hearing.
Overturn of gas cylinder and blowout of
gas flow regulator can cause injury.
