OUTPUT PANEL CONTROLS

WELDER/GENERATOR CONTROLS

See Figure B.1 for the location of the following features:

1.OUTPUT CONTROL: Allows full range adjustment of welding current or voltage.

2.ARC CONTROL: The “ARC CONTROL” potentiome-

ter is active in two modes: “STICK/TIG” and “WIRE WELDING” with different purposes in each mode.

3.MODE SWITCH: Selects three possible modes of welding operation, 1.) CC Stick/Tig welding, 2.) Pipe welding, and 3.) CV Wire Welding.

4.LOCAL/REMOTE CONTROL SWITCH: Allows the operator to control welding output at the welding con- trol panel or at a wire feeder, TIG amptrol, or a K857 remote control.

5.WELDING TERMINALS SWITCH: The toggle switch labeled “WELDING TERMINALS ALWAYS ON” and

“WELDING TERMINALS REMOTELY CON-

TROLLED” is used to control the operation of the solid state output contactor. With the switch in the “WELDING TERMINALS ALWAYS ON” position, the contactor is closed at low and high idle.

6.BATTERY CHARGER CIRCUIT BREAKER: Opens the engine battery circuit if a short develops. Engine will not crank if this circuit breaker is open.

7.WIRE FEEDER POWER CIRCUIT BREAKER: Opens the wire feeder circuit and disables the feeder if a fault is detected in the circuit.

8.15 AMP, 120 VOLT DUPLEX RECEPTACLES: Connection point for supplying 120 volt power to oper- ate one or more electrical devices.

9.50 AMP, 120/240 VOLT RECEPTACLE: Connection point for supplying 240 volt power to operate one electrical device.

10.WELD OUTPUT TERMINALS WITH FLANGE NUT: Provides the connection point for the electrode and work cables.

11.GROUND STUD: Provides a connection point for connecting the machine case to earth ground for the safest grounding procedure.

12.6 PIN AMPHENOL: For attaching optional remote control equipment to the GX-271.

13.14 PIN AMPHENOL: For attaching wire feeder con- trol cables to the GX-271 (Includes contactor closure circuit, remote control circuit, wire feeder 115/42 volt power source).

14.WIRE FEEDER VOLTMETER POLARITY SWITCH: matches polarity of wire feeder voltmeter to polarity of electrode.

15.ENGINE RUN-STOP SWITCH: Energizes engine cir- cuit.

16.ENGINE START PUSHBUTTON SWITCH: Energizes starter solenoid contactor and fuel sole- noid.

17.ENGINE CHOKE

18.AUTO IDLER SWITCH: In the “AUTO” mode, the engine goes to low idle speed 12 seconds after a welding or auxiliary power load is removed. Engine goes to high speed when the load is re-applied.
