15. CIRCUIT BREAKERS These circuit breakers provide separate overload cur- rent protection for each 120V circuit at the 240V recep- tacle, each 120V receptacle, the 120VAC in the 14-Pin connector, the 42VAC in the 14-Pin connector and (for codes above 10871 only) battery circuit overload pro- tection.

16. 120VAC RECEPTACLES

These two 120VAC (5-20*R) receptacles provide 120VAC for auxiliary power. These receptacles have a 40* amp total rat- ing. Refer to the AUXILIARY POWER RECEPTACLES sec- tion in the installation chapter for further information about these receptacles. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.

* 15 Amps per receptacle up to 30 Amps total for codes below 10500 only.

17. 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 information.

18. VOLTMETER +/- SWITCH

Changes the polarity display on the wire feeder.

19. 14 - PIN CONNECTOR

For attaching wire feeder control cables. Includes con- tactor closure circuit, auto-sensing remote control cir- cuit, and 120V and 42V power. The remote control cir- cuit operates the same as the 6 Pin Amphenol.

20. ARC CONTROL

The ARC CONTROL WIRE/STICK dial is active in the WIRE and STICK modes, and has different functions in these modes. This control is not active in the TIG and PIPE modes.

CC-STICK mode: In this mode, the ARC CONTROL knob sets the short circuit current during stick welding (arc-force). Increasing the number from -10 to +10 increases the short circuit current and prevents stick- ing of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with a setting at 0.

CV-WIRE mode: In this mode, turning the ARC CON- TROL clockwise from –10 (soft) to +10 (crisp) changes the arc from soft and washed-in to crisp and narrow. It acts as an inductance control. The proper setting depends on the procedure and operator preference. Start with a setting at 0.

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 filter hous- ing 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 (K1585-2 only for codes 10871 and below) 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 (K1585-2 only for codes 10871 and below), the engine will shutdown 30 minutes after starting. If any other indicator light is on after starting, the engine will shutdown 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

With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about 0°F. With the above and the optional ether starter kit (K887-1), the engine should start satisfactorily down to about -20°F. With the above and an oil pan preheating system* the engine should start satisfactorily down to about -30°F. With the above and a battery warmer*, the engine should start satis- factorily down to about-40°F.

*Contact your local Lincoln Electric Representative for sug- gested after-market kits.

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
