5-1. VRD (Voltage Reduction Device)
The equipment includes a voltage reduction device
on the weld output side. The voltage reduction
device reduces the output voltage of the welder
when welding is paused in order to further
increase safety when welding in locations with
high humidity, elevated locations, extremely
confined spaces near possible hazards, and
similar conditions.
When the VRD switch is set to "ON" and not welding, the voltage reduction device
reduces the voltage of the Weld output terminals to 35 V or less.
When welding is started, the voltage-reduction function is cancelled and the
equipment returns to the reduced voltage status when welding is completed.
Turning the VRD switch to "OFF" also cancels the voltage-reduction function.
The green VRD lamp ("BELOW 35V" side) lights up when weld output voltage is
less than 35 V and the red lamp ("AT OR ABOVE 35V" side) lights up when the
voltage is 35 V or more.
<Note>
•The VRD is only for weld output. It does not function for AC generated output
voltage.
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","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 eight 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 0.5 A 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" 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).
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 "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 arc control dial of the
short-circuit current of the weld output.
<Note>
•The arc control function is only for "CC-STICK" mode. It does not function if using
"CV-WIRE".
•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 (Option)
You can connect the remote controller to the
remote control connector to enable remote
operation of weld current adjustment.
1) Remove the remote control cover from the
operation panel. (6-M4 screws)
2) Connect the plug of the extension cord
(cord reel) into one of the dedicated remote
control connector (side A or B).
3) Connect the plug of the remote controller
into the receptacle of the extension
cord (cord reel). Up to 3 cord reels (30 m x
3) can be connected.

<Note>
•The output control dial on the remote controller connection side of the equipment
does not function when a remote controller is connected.
•If the remote controller is disconnected from the remote control connector while
welding, the equipment output control dial becomes functional, possibly resulting
in an increase or decrease in weld current.
•Do not connect the remote controller plug to the receptacle of an extension cord
(cord reel) that is connected to AC power source. Improper connection causes the
caution lamp of the remote controller to light up indicating a fault.
•Do not connect the receptacle of an extension cord (cord reel) used for the remote
control to any other device besides the remote controller.
•Set the breaker to "ON" if the cord reel is equipped with one.
5-5. Meter
The equipment includes a DC meter that provides digital display of both weld
current and voltage, and an AC meter that provides digital display of both voltage
and frequency of 3-phase generated output.
(1) DC Ammeter – Voltmeter
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 "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.
(2) AC Meter
The AC meter displays of both 3-phase voltage and frequency.
<Note>
•During operation, the AC meter displays constantly the 3-phase output voltage of
the AC power source regardless of whether the breaker is set to "ON" or "OFF".

Caution: Burn
•The engine, muffler and similar parts are extremely hot during operation and
immediately after stopping the equipment. Never touch hot parts.
6-1. Engine Oil Inspection
Caution: Burn
•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.
Situate the equipment on a level surface
and completely insert the oil gauge to
inspect the oil level.
Inspect the oil level before starting
operation and, if it has decreased, fill with
oil until it reaches the maximum level.
<Note>
•The oil level cannot be accurately
checked if the equipment is at an
angle.
•Operating the equipment when the oil
has been filled above the maximum
level can result in engine cylinder
internal damage.
■Engine Oil Selection
Use a diesel-type engine oil with a viscosity that is appropriate for the outdoor air
temperature (refer to the table).
<Note>
•Use oil with a quality of CD class or better (API classification).

．Cooling Water Inspection
Caution: Burn
•Never open the radiator cap during operation or immediately after stopping the
equipment. Hot cooling water and steam will spurt out.
Check that the sub tank cooling water level is within the range of "FULL" and
"LOW".
If the cooling water level is lower than "LOW", add water to both the sub tank and
radiator.

<Note>
•Use a long-life coolant (LLC) in order to
prevent freezing and rust. (An LLC with a 30%
mixing ratio is used when shipped from the
factory.)
•Use an LLC mixing ratio in the range 30% to
45% in accordance with the outdoor air
temperature.
•Change the LLC every 2,000 hours or 1 year.

．Fuel Inspection
Warning: Fire
•Always be sure to stop the engine when inspecting fuel or refueling, and
absolutely never perform such tasks near fire or other open flame. Wait until the
engine has completely cooled before inspecting fuel or refueling.
Check that there is sufficient fuel and add fuel if insufficient.
After refueling, securely tighten the tank cap and close the fuel inlet cover.
<Note>
•Use ASTM D975 No. 2-D diesel fuel. Do
not use a substitute fuel of unknown
quality as this can negatively affect the
engine.
•Use a cold-weather fuel that conforms to
ASTM standards if using the equipment
in a cold weather region.
•Shindaiwa recommends using a fuel with a sulfur content of less than 1,000 ppm.
