5. Equipment 5-1. Eco Welding The equipment is incorporates an Eco welding feature that provides lower noise levels, lower fuel consumption and lower gas emissions than conventional welder-generators. When you turn the idle control switch to Eco, you will be able to weld at Max. with a 4.0mm welding rod at the low speed.
Page 11 Caution: Burns Do not touch the engine or exhaust during operation or immediately after stopping the equipment, as the temperature will be extremely high. When the water temperature rises abnormally, the coolant/water temperature monitor lamp will flash, and the automatic engine shut-off will be engaged. When this symptom occurs, check the coolant sub tank, and replenish if needed.
Page 12: Remote Control
5-4. Remote Control The equipment incorporates a Remote Control receptacle. Remote control box is an optional part. Remote Control operation is available by connecting the compatible Remote Controller to the receptacle. REMOTE CONTROL RECEPTACLE REMOTE CONTROL BOX 5-5. Earth Leakage Relay and Grounding Danger: Electric Shock Ground the grounding terminal to the earth as set out in the manual.

(2) Operation Check Before operating the equipment, always check if the safety shut-down device works as shown in the following procedure. 3-PHASE ELCB TEST BUTTON 1-PHASE ELCB LEAKAGE INDICATION WHITE LEVER BUTTON BLACK LEVER TEST BUTTON ① Ensure that the circuit breakers and load switches are positioned to [OFF].
Page 14: Emergency Stop Switch
<Caution> When the load of less than 0.5A is connected, the Auto Idle feature may not function. In this case, turn the switch to [HIGH]. When welding operation or electric supply performs alternately or intermittently, turn the switch to [HIGH]. 5-7.
Page 15: 6-3.Checking Fuel
Danger: Injuries Do not open the radiator cap while operating this equipment or immediately after stopping the equipment, to prevent burns from hot steam or water. Caution: Burns Do not touch the engine and muffler during operation and immediately after stopping the equipment, for the temperature could reach extremely high temperature.
Page 16: 6-5.Checking Battery
<Caution> Use Diesel fuel, ASTM D975 No.2-D in the event ambient temperature reaches down to -5 ℃ . The engine is designed to use either No.1-D or No.2-D Diesel fuel. However, for better economy, use No. 2-D Diesel Fuel whenever possible. At temperatures less than -7 ℃...
Page 17: Operation
① Check the fluid level. If the level is near or lower than LOWER level, add distilled water until the fluid level reaches UPPER level. ② Make sure that the battery cables are firmly secured to the posts. Tighten the clamps if necessary. <Caution>...
Page 18: Starting
7-1. Starting ① Turn the breakers (1-P, 3-P) to [OFF] ② Turn the Fuel lever to [OPEN]. ③ Turn the Idle Control Switch to [ECO] or [AUTO]. ④ Ensure the Emergency Stop Switch is in released position. ⑤ When the temperature is below -5 ℃ , t urn and keep the Starter switch to PREHEAT until the preheat lamp turns off (about 5 seconds).
Page 19: 7-3.Emergency Stop
<Caution> Do not attempt to turn to [STOP] position while actual welding or utilizing AC power source, it may cause the serious damage on the unit. 7-3. Emergency Stop An Emergency Stop feature is incorporated in the equipment. Push the Emergency Stop Switch in case of an emergency or if an equipment fault develops during operation.
Page 20: 8-3.Connection-Welding Cable
8-2. Polarity There are two welding output terminals, 『＋＋＋＋』 a nd 『－－－－』 . Select the polarity according to the operation, referring to the table below. <Caution> Follow the instruction of the welding rods, the polarity of which is specified. Application Connection Generals Welding, such as...
Page 21 8-5. Welding Caution: Suffocation from welding fumes Be sure to wear a fume proof mask during operation, because welding fumes contains poisonous gas and dust. Pay attention to the airflow direction and sufficient ventilation also in order to prevent from inhaling the fume. Caution: Injuries to eyes and skin Be sure to wear spark protection glasses (Refer to the table below), long-sleeve shirts, gloves, etc.
