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
specifiedby the applicable law (occupational safety
and healthregulation, rules on preventing injury by
inhaled dustor etc.), or wear protective breathing
gear.
(3)When conducting welding in a confined area,
makesure to provide sufficient ventilation or wear
protective breathing gear and have a trained
supervisorobserve 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 isperformed can generate toxic
gases.
(5)When welding a coated steel plate, provide
sufficientventilation 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
thework site to prevent them from being exposed to
thespatter. If they cannot be relocated, cover them
with afireproofing 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
tothe welding part.
(7)Do not weld a sealed tank or a pipe that contains
agas.
(8)Keep a fire extinguisher near the welding site for
anemergency.

IV
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.

3.2RATED DUTY CYCLE
The rated duty cycle of this welding machine is 60 %. This means that the machine can weld for a total of 6minutes
out of any 10 minutes at the rated current, and then must cool down during the remaining 4 minutes to prevent
overheating.
As shown on the right figure, the allowable duty cycle varies with the output current. A duty cycle on the curved line
can be calculated using the following formula.
2
Rated Output Current
Allowable Duty Cycle Rated Duty Cycle
Actual Ouput Current
（ ）
• Observe the lowest allowable duty cycle of the welding system components (typically either the welding machine
or the torch).
• Exceeding allowable duty cycle will cause the unit to stop automatically (with error displayed) or burning.
• If the ambient temperature is higher than 40 °C, limit the duty cycle to a level lower than the result of the formula.
• Output current values for pulsed welding are the average of the base and peak current values.

For your reference:
Duty cycle:
The percentage ratio of loading time to full time. A cycle of the full time shall be 10 minutes.
Rated duty cycle:
means the rate of use when loading the rated output current intermittently at the rated input voltage of the rated
frequency. Regarding the engine-driven welding power unit, however, it means when driving it at the rated number
of revolution.
3.3THERMAL PROTECTION
Welding power source is equipped with a thermal switch at the radiator fin of IGBT to monitor the temperature.
