17. 120VAC RECEPTACLES

These two 120VAC (5-15R) receptacles with GFCI pro- tection provide 120VAC for auxiliary power. These receptacles have a 20 amp total rating. Refer to the AUXILIARY POWER RECEPTACLES section in the installation chapter for further information about these receptacles. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.

18. 15 AMP CIRCUIT BREAKERS These circuit breakers provide separate overload cur- rent protection for each 120V receptacle.

19. GROUND STUD

Provides a connection point for connecting the machine case to earth ground for the safest grounding procedure. Refer to “MACHINE GROUNDING” in the Installation chapter for proper machine grounding infor- mation.

WIRE FEEDER MODE CONTROLS

(Items 20 - 24 Stick & Wire model only)

20. WELD OUTPUT TERMINAL - WIRE

This 1/2-13 stud with flange nut provides a welding connection point for the electrode and work cables. For positive polarity welding the electrode cable connects to the “+” terminal and the work cable connects to this “-” terminal. For negative polarity welding the work cable connects to the “+” terminal and the electrode cable connects to this “-” terminal.

21. 15 AMP CIRCUIT BREAKER

This circuit breaker provides overload protection for the 14-pin connector.

22. VOLTMETER +/- SWITCH

Changes the polarity display on the wire feeder.

23. VOLTS-AMPS SWITCH

Switches the display between volts and amps.

24. 14 - PIN CONNECTOR

For quick connection of wire feeder control cable.

ENGINE OPERATION

STARTING THE ENGINE

1.Open the engine compartment door and check that the fuel shutoff valve located to the left of the fuel fil- ter housing is in the open position (lever to be in line with the hose).

2.Check for proper oil level on the oil dipstick. Close engine compartment door.

3.Remove all plugs connected to the AC power receptacles.

4.Set IDLER switch to “AUTO”.

5.Set the RUN/STOP switch to “RUN”. Observe that all engine protection lights momentarily turn on, some lights may turn off before starting. Check the fuel gauge to make sure that there is an adequate fuel level.

6.Press and hold the engine START button for a minimum of 2 seconds.

7.Release the engine START button when the engine starts.

8.Check that the indicator lights are off. If the LOW FUEL light is on , the engine will shutdown 30 minutes after starting. If any other indicator light is on after starting, the engine will shut- down in a few seconds. Investigate any indicated problem.

9.Allow the engine to warm up at low idle speed for several minutes before applying a load and/or switching to high idle. Allow a longer warm up time in cold weather.

COLD WEATHER STARTING / RUNNING

With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about 0°F. If the engine must be frequently started below 10o F, it may be desirable to install the optional ether starter kit (K825-1). Installation and operating instructions are included in the kit. Use ether starting only when required because excessive use shortens engine life. If the engine must be operated in extreme cold environments 0°F to -35°F (-18°C to -37°C) an optional Cold Weather Kit (K1665-1) is available. Installation and operating instructions are included in the kit.

STOPPING THE ENGINE

1.Switch the RUN/STOP switch to “STOP”. This turns off the voltage supplied to the shutdown solenoid. A backup shutdown can be accomplished by shutting off the fuel valve located on the fuel filter housing.

BREAK-IN PERIOD

The engine used to supply power for your welder is a heavy duty, industrial engine. It is designed and built for rugged use. It is very normal for any engine to use small quantities of oil until the break-in is accom- plished. Check the oil level twice a day during the break-in period (about 200 running hours).

IMPORTANT

IN ORDER TO ACCOMPLISH THIS BREAK-IN, THE UNIT SHOULD BE SUBJECTED TO HEAVY LOADS, WITHIN THE RATING OF THE MACHINE. AVOID LONG IDLE RUNNING PERIODS.
