The low noise, the lower fuel consumption and the low gas emission than those of conventional models.
When you turn the selector switch to Eco, you will be able to weld with Max 4.0mmφrod at the slow
down speed.
＜
＜＜
＜ Caution ＞
＞＞
＞
●When welding is performed, do not turn the output selector switch which causes the burnout of the
switch
●Eco is designed for welding only. The breaker activates to TRIP, in case it is used for AC Output
5-2. Display
The equipment is incorporated in Digital Display. It displays 『 Voltage 』 , 『 Hour 』 , 『 Speed 』 successively,
by changing the display selector switch.
＜
＜＜
＜ Caution ＞
＞＞
＞
●During operation, voltage meter always displays the voltage in 200/220V, 3-Phase both at the
breaker position 『 ON 』 and 『 OFF 』 .
5-3. Frequency Selection
Selector either 50 or 60Hz by the selector switch on the front panel, in accordance with the load
frequency.
5-4. Monitor Lamp
The equipment incorporates monitor lamps as 『 Water Temperature 』 , 『 Battery Charging 』 and 『 Oil
Pressure 』 .
Under normal condition, when the starter switch is turned from 『 STOP 』 to 『 REN 』 , the lamps of, 『 BATTERY
CHARGING 』 and 『 OIL Pressure 』 turned To ON and all the lamps turn to OFF after the Engine starts.
When abnormality happens in running, monitor lamps flicker
And the engine stops automatically.
In the case the automatic shutdown is engaged, turn the starter switch to STOP once, and then restart
the engine. When the automatic shutdown is engaged again, check which lamp turns ON or OFF and
point out where the abnormality is.

Danger: Injuries
●Close all the doors and place lock during operation, to avoid injuries by unintentional touch
of cooling fan or fan belt.
(1) Water Temperature Monitor Lamp
When the water temperature rises abnormally, the water temperature lamp flashes and the automatic
shutdown will be engaged.
When this happens, check water tank and replenish if needed. （ Refer to 『 6-2. Check the water
temperature 』
If the water level is normal, there may be possibility of overload. Always use the equipment within the
rated duty cycle and output power.
(2) Battery Charge Monitor Lamp
When the battery charge becomes unable during operation, the monitor lamp flashes and the automatic
shutdown is engaged.
Please consult with our authorized distributor or service section.
＜
＜＜
＜ Caution ＞
＞＞
＞
●The monitor cannot detect battery degradation or insufficient battery liquid.
Be sure to check battery liquid level periodically.
(Refer to 『 6-5. Battery Check 』 )
(3) Oil Pressure Monitor Lamp

12
Caution: Burns
●Do not touch the engine and muffler during operation and immediately after stopping it, for the
temperature can reach extremely high
●When checking engine oil or changing oil, always stop the engine, and wait until the engine
cools down. If you open either the oil gauge or the oil plug during operation, hot oil may cause
some injuries.
When the oil pressure drops during operation, the monitor lamp flashes and the automatic shutdown is
engaged. When this occurs, check the engine oil level and replenish the maximum level if needed.
＜
＜＜
＜ Caution ＞
＞＞
＞
●The monitor cannot detect the degradation of engine oil. Please check engine oil periodically and replenish if
needed.
(Refer to 『 11. Checking and Maintenance 』 )
●Check fuse next, when the abnormality other than 『 Water Temp 』 , 『 Charge 』 or 『 Oil Pressure 』 is detected.
If a fuse is burnet, consult with our authorized distributor or our service section, because there may be an
abnormality of electric/electronic parts or wiring and repairing may be required.
(Refer to 『 4. Parts 』 )

3 Insert the plug into the receptacle of extension cord reel.
You can use 3 reels in series (30mx3)
＜
＜＜
＜ Caution ＞
＞＞
＞
●Never connect a remote control box plug to a receptacle of extension reel connected to AC100/110 Output
receptacle in the equipment. The abnormality lamp in the box turns ON to show abnormality when it is
connected by mistake.
●Never connect any device to a receptacle in the extension reel other than a remote controller.
●In case of using the cord reel incorporating ELCB set the ELCB ON and use.
5-6. ELCB and Grounding
Danger: Electric Shock
●Ground every grounding terminal to the earth as set in the manual. If even one of all is unconnected by
mistake or accident, it will make much more dangerous for human than the NO RELAY case, because
leaking current inevitably goes through the body.
●Even though all the terminals of the loads have been grounded to the earth, the bonnet grounding
thermal should be grounded to the earth.
●Grounding should be made after the engine stopped.
●Whenever the ELCB relay has activated, you should repair the leaking part always first of all.
＜
＜＜
＜ Caution ＞
＞＞
＞
●The ELCB activates only for AC output.
●ELCB activates when AC output is used with the output selector switch at 『 ECO 』 position for protection
load damage.
The circuit breaker is incorporated with ELCB to protect electric shock
The breaker trips when current leakage is detected due to insufficient insulation of loads
The specifications of ELCB are as follows.
●Rated Sensitive Current
less than 30mA (Grounding Resistance less than 500Ω)
●Activation Time less than 0.1 second

14
(1) Grounding
A qualified electrician should perform the grounding work for the following 3 points. (Ground Resistance
less than 500Ω)
●The ELCB grounding terminal
●The bonnet grounding terminal
●The load bonnet terminal
＜
＜＜
＜ Caution ＞
＞＞
＞
●In the event you cannot ground, consult with our
authorized distributor or our service section.
(2) Operation Check
1. Turn a tarter switch from 『 STOP 』 to 『 RUN 』 .
2. Set the breaker lever to 『 ON 』 .
3. Push a test button in the breaker.
(The device is normal when ELCB Lamp (Red) turns ON and the lever positions at the middle of
『 ON 』 and 『 OFF 』 ).
4. Push the reset button.
(The ELCB lamp (red) turns OFF)
5. Push down the breaker lever 『 OFF 』 .
6. Proceed with engine start procedure once returning a starter switch to 『 STOP 』 .
In the event you cannot complete all steps as above, the device is out of order. Consult with our
authorized distributor or our service section.

(3) The ELCB has activated
Caution: Electric Shock/Injuries
●Be sure to disconnect all the loads to the equipment when turning the breaker ON
again after ELCB has activated.
ELCB lamp (Red) turns ON and the breaker lever positions at the middle of 『ＯＮ』 and 『 OFF 』 .
In that case, reset the ELCB per the following procedure after having finished the leaked points.
1. Push the reset button.
2. Push the breaker lever down to 『 OFF 』 .
The above procedure brings restoration of the breaker lever to 『 ON 』 .
＜
＜＜
＜ Caution ＞
＞＞
＞
●In the case ELCB monitor lamps keep OFF on using, it means that
AC Output over supply or AC output Supply under output selector switch positions at ECO. Refer to 『 9-3.
Operation 』 to recover.
5-7. Slow-down Feature
The Slow-down feature is to set the engine speed low automatically (in about 8seconds) for the purpose of
reducing noise and fuel consumption, whenever no welding operation or electric supply is performed.
In the case of using the Slow-Down feature, turn the slow-down switch to ON. By the condition, the engine
automatically moves to high speed, whenever welding operation or electric supply starts.
△Caution: Damage to properties
●When using the load with magnet switch, turn the slow-down switch 『 OFF 』 .
＜
＜＜
＜ Caution ＞
＞＞
＞
●When the load less than 0.5A are connected to use, the slow-down feature does not function
sometimes. So, turn the switch 『 OFF 』 .
●When welding and AC supply are used alternately or intermittently, turn the switch 『 OFF 』 .
●When the output selector switch is at 『 ECO 』 ,the engine does not turn to high speed.

16
△Caution: Fire/Burns/Injuries
●When checking engine, always stop the engine and keep away from hire.
Wait until the engine cools down before performing any check.
6-1. Engine Oil
When checking engine oil, be sure to
Keep the equipment leveled and insert
The oil gauge all the way in.
Before starting the equipment, make
Sure to fill the engine oil to the UPPER
Line through the oil inlet.
＜
＜＜
＜ Caution ＞
＞＞
＞
●If the equipment is not levels, you cannot obtain accurate oil level. Do not overfill (over UPPER line) the
engine oil. The excessive oil may damage the engine (inside cylinder).
■Selection of proper engine oil
Select the proper viscosity engine oil in compliance with ambient temperature. (Refer to the chart below)
＜
＜＜
＜ Caution ＞
＞＞
＞
●Use the API class CD or higher.
