5. Equipment
5-1. Spill Containment
Warning: Fire
 Always be sure to wipe up any spilled fuel or oil.
 Spilled fuel and oil accumulates in the spill containment. Do not operate the
equipment with liquid accumulated in the spill containment.
 Absolutely never use the equipment if there is a fuel, oil or cooling water leak, and
be sure to always repair the leak before using.
The equipment includes a spill containment (structure that collects leaking liquid) in
order to prevent leaking liquid from getting outside of the equipment if oil, fuel or other
liquid should leak. Before starting operation, check if there is any fluid accumulated in
the spill containment and drain any accumulated liquid. (Refer to section "13.(8)
Draining Liquid from the Spill Containment".)
<Note>
 It is necessary to periodically drain the liquid from within the equipment because any
rainwater that leaks into the equipment also accumulates in the spill containment.
 Although the fluids that can leak internally consist of oil, fuel and cooling water, the
spill containment does not have a function that can separate rainwater that has
leaked into the equipment from these internally leaked fluids. Properly dispose of
liquid drained from the spill containment in a manner according to the applicable laws
and regulations.
5-2. Idle Control
The equipment includes an idle control function.
You can use the idle control switch to select an
engine speed setting of "AUTO" or "HIGH".
(1) Auto Idle
The equipment includes an auto idle function in order
to reduce noise, save fuel, and reduce exhaust gas
emission.
You can set the idle control switch to "AUTO" so that the engine operates at low speed
when not welding or using the equipment as a power source.
When you start to weld or use as an AC power source, the engine automatically
increases to high speed. When in a no-load condition, the engine automatically returns
to low speed after approximately 8 seconds of high-speed operation.
<Note>
 Set the idle control switch to "HIGH" if using a high capacity motor, precision
instruments or AC load with an attached magnetic switch.
 Set the idle control switch to "HIGH" if using as an AC power source of a device of
0.5A or less because the engine might not reach a high speed as speed control does
not operate at that level.
(2) High Idle
You can set the idle control switch to "HIGH" to maintain the engine constantly at high
speed.

5-3. Weld Output Control
(1) Weld Mode Selector
You can select a weld mode of "CV-
WIRE", "DROOP-STICK", "GOUGING",
"LIFT START TIG" or "CC-STICK" in
accordance with the type of welding being
performed.
 CV (Constant Voltage) -WIRE
You can use the equipment as a
power source for semi-automatic arc
welding (MIG, MAG and self-
shielded).
 DROOP (Drooping Characteristic)–STICK, GOUGING
The weld current can be adjusted by manipulating the welding rod due to being
able to increase or decrease the current for changing the arc length, thereby
allowing you to adjust the arc status and weld beads.
The arc start is good and the arc is strongly felt.
This mode is optimal for welding work such as pipe welding or when using special
welding rods.
 LIFT START TIG
The (DC) TIG welding (Lift Start) is available in this mode. The arc is generated by
bringing the tungsten electrode into contact with the base material once and then
lifting it up.
 CC (Constant Current) -STICK
Welding can be performed at a constant uniform current even if the arc length
changes due to a shaky hand or similar cause to provide a stable arc that is not
easily extinguished.
Welding can be performed at a specified current value without being affected by
the length or thickness (thinness) of the welding cable.
This mode is optimal for general welding as the stable arc reduces the amount of
spatter.
(2) Weld Output Pre-Set
The equipment includes a weld output pre-set function.
If the weld mode selector is set to "CV-WIRE", you can pre-set the output voltage using
the output control dial.
If the weld mode selector is set to "DROOP-STICK", "GOUGING", "LIFT START TIG"
or "CC-STICK", you can pre-set the output current using the output control dial.
(3) Arc Control (for CC-STICK mode)
The equipment includes an arc control function that adjusts
the arc strength.
You can adjust the setting of the short-circuit current of the
weld output by turning the arc control dial.
<Note>
 The arc control function is only for "CC-STICK" mode. It
does not function if using "CV-WIRE","DROOP-STICK",
"GOUGING" or "LIFT START TIG".
 Always turn the arc control dial to "0"(zero) when the scratch start TIG welding is
functioned otherwise a welding current becomes unstable as the arc control is
functioned.

5-4. Remote Control (9-Pin Connector)
You can connect a compatible remote controller to
the 9-pin connector to enable remote operation of
weld output adjustment.
<Note>
 The output control dial for the remote control
connection side of the equipment does not
function when a remote controller is connected.
 If the remote controller is removed from the
remote controller receptacle while welding, the
equipment output control dial becomes
functional, possibly resulting in a sudden
increase or decrease in weld output.
5-5. DC Meter
The equipment includes a DC meter (DC Ammeter - Voltmeter) that provides digital
display of both weld current and voltage.
The DC ammeter and voltmeter display the weld
output for both outputs A and B separately.
If the single/dual selector is set to "SINGLE", the DC
meter for output B does not display current or
voltage.
<Note>
 If the weld mode selector is set to "CV-WIRE", the
set voltage that has been pre-set using the output
control dial is displayed by the voltmeter when not
welding. (The DC ammeter display is blank when
not welding.)
 If the weld mode selector is set to "DROOP-STICK", "GOUGING", "LIFT START TIG"
or "CC-STICK", the set current that has been pre-set using the output control dial is
displayed by the DC ammeter when not welding. (The voltmeter display is blank when
not welding.)
 During welding, both the DC ammeter and voltmeter display the actual output values.
When welding is completed, both meters display the actual output values for
approximately 8 seconds, after which display returns to the pre-set values.
5-6. Display
The equipment includes a display that provides operation status.
(1) AC Meter
The equipment includes an AC Meter that displays the
three phase 380/415V generated output.
The AC meter is equipped with an AC Meter Selector that can
be switched to display voltage, current or frequency.
<Note>
During operation, the three phase 380/415V output
voltage of the AC power source is constantly displayed
regardless of whether the breaker is set to "ON" or
"OFF".

(3) Spill Containment Inspection
The display of spill containment inspection ("SPC") lights
up if the level of liquid in the spill containment is
approximately approx. 18 L in order to ensure that liquid
accumulated in the spill containment does not spill out of
the equipment. If this occurs, drain the accumulated liquid
from the equipment. (Refer to section "13.(8) Draining
Liquid from the Spill Containment".)
<Note>
 The engine is not stopped if the spill containment
monitor lamp lights up during operation.
 When the spill containment monitor lamp lights up during operation, stop the engine,
check for fuel, oil and cooling water leakage, and repair as necessary.
 Do not use the equipment with liquid accumulated in the spill containment. Drain the
spill containment before using. (Refer to section "13.(8) Draining Liquid from the
Spill Containment".)
5-7. Error Code Display
The equipment includes an error code display function that notifies the operator of any
errors during operation. If an error is detected during operation, error codes are
displayed by the DC and AC meters. If this occurs, stop operation immediately, and
inspect and repair the location where the error has occurred.

fans and belts.
Caution: Burn
 The engine, muffler and similar parts are extremely hot during operation and
immediately after stopping the equipment. Never touch hot parts.
 Never open the radiator cap during operation or immediately after stopping the
equipment. Hot cooling water and steam will spurt out.
 Always be sure to stop the engine and allow it to cool before inspecting or changing
the engine oil. Opening the oil gauge or oil plug during operation will result in hot oil
spurting out.
The equipment includes monitor lamps for water
temperature, battery charge and oil pressure.
If the equipment is normal, the "CHARGE", "OIL
PRESS" and "PREHEAT" monitor lamps light up when
the RUN/STOP switch is switched to "STOP" to
"RUN", and all monitor lamps turn off when the engine
is started. If any error occurs during operation, the
corresponding monitor lamp lights up and the engine is
automatically stopped. If the engine is automatically
stopped, return the RUN/STOP switch to "STOP" and
restart the engine. Watch the lit/unlit status of the
monitor lamps the next time an automatic stop occurs
and check the error contents.
(1) Water Temperature Monitor Lamp
The water temperature monitor lamp ("WATER TEMP") lights up and the engine is
automatically stopped if the cooling water temperature becomes irregularly high during
operation. If this occurs, inspect the water level of the sub tank and add cooling water if
the water level is insufficient. (Refer to section "7-2 Cooling Water Inspection".)
If the cooling water in the sub tank is at the specified level, it is probable that
overloading is the cause. Use within the rated output.
(2) Battery Charge Monitor Lamp
The battery charge monitor lamp ("CHARGE") lights up and the engine is automatically
stopped if battery charge fails during operation. If this occurs, it is probable that there is
fan belt damage or a wiring fault. Request repair at the retail outlet where the
equipment was purchased.
(3) Oil Pressure Monitor Lamp
The oil pressure monitor lamp ("OIL PRESS") lights up and the engine is automatically
stopped if the engine oil pressure drops during operation. If this occurs, inspect the
engine oil level and fill with engine oil until it reaches the maximum level.
<Note>
 The oil pressure monitor cannot detect oil deterioration. Change the engine oil
periodically. (Refer to section "13. Inspection/Maintenance".)
 The charge monitor cannot detect battery deterioration or insufficient battery fluid.
Inspect the battery fluid level periodically. (Refer to section "7-6. Battery Inspection".)
 Inspect the fuses if the engine is automatically stopped and none of the monitor lamps
("WATER TEMP", "CHARGE" and "OIL PRESS") light up. (Refer to section "4. Part
Names" for fuse location.)
If a fuse has blown, it is probable that there is a fault in an electric part or the wiring.
Request repair at the retail outlet where the equipment was purchased.

5-9. Earth Leakage Circuit Breaker and Grounding
Warning: Electric Shock
 Always be sure to repair the corresponding earth leakage location when earth
leakage circuit breakers operate.
Warning: Fire
 Do not ground wiring of earth leakage circuit breakers of the equipment to piping
that passes through flammable material.
The equipment includes earth leakage circuit breakers (solidly grounded type) in order
to prevent electric shock. Immediately isolate the electrical circuit if earth leakage
occurs due to insulation failure in devices using the equipment or similar reason.
(1) Operation Check of Earth Leakage Circuit Breaker
Be sure to always check the earth leakage circuit breakers before starting operation
according to the following procedures.
1) Start the engine.
(Refer to section "8-1. Starting the Engine".)
2) Set the idle control switch to "HIGH".
3) Set the ELCB lever to "ON".
4) Press the ELCB test button.
Operation is normal if the ELCB lever lowers and turns
off at this time.
5) Push up the ELCB lever to the "ON" position.
There is a fault in the earth leakage circuit breakers if
operation cannot be checked according to the above
procedures. Request repair at the retail outlet where the
equipment was purchased.
(2) Bonnet Grounding Terminal
The equipment includes a bonnet grounding terminal in
order to connect bonnet ground wire.
A neutral point of the AC power source is connected to
the bonnet grounding terminal.
<Note>
 Connect using a plug with a grounding pole.
 If using a plug without a grounding pole, perform grounding work and check that used
devices are connected to ground.
 Securely ground the bonnet grounding terminal to the metal frame of the vehicle if
transporting the equipment by truck or trailer.
(3) If an Earth Leakage Circuit Breaker Operates
Caution: Electric Shock/Injury
 Always be sure to turn off the power switches of all devices using the equipment
when turning on the equipment breakers after an earth leakage circuit breakers
operates. Leaving on the power switch of a device using the equipment when the
equipment breakers are turned on could result in the sudden operation of the
corresponding device.
The ELCB lever moves to "OFF" when earth leakage circuit breakers operate.
When this occurs, immediately stop the engine and repair the earth leakage location.
After repairing all faults, push up the ELCB lever to the "ON" side to reset the system.
