OUTPUT PANEL CONTROLS

WELDER/GENERATOR CONTROLS

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

1.OUTPUT RANGE SELECTOR: Selects continuous current output for constant current stick or TIG appli- cations (blue settings) and constant voltage wire feed applications (red settings). The amperages on the dial correspond to the maximum amperages for each corresponding range setting. Never change the range switch setting while welding since this could damage the switch.

2.FINE OUTPUT CONTROL: Allows fine adjustment of current or voltage within the selected output range.

3.POLARITY SWITCH: Selects DC+, DC- or AC weld- ing output. Color codings aid in the proper selection of stick (blue) or wire feed (red) polarity setting. On the RANGER 300 DLX the color setting of the polarity switch must match the color setting of the OUTPUT RANGE SELECTOR. Never change the polarity switch setting while welding since this could damage the switch.

4.CONTROL AT WELDER/REMOTE CONTROL SWITCH: Allows the operator to control welding out- put at the welding control panel or at a remote station. Remote connections are made at the 6 pin or 14 pin amphenol connector.

5.WELDING TERMINALS SWITCH (DLX Model Only) The toggle switch labeled “WELDING TERMINALS ALWAYS ON” and “WELDING TERMINALS REMOTELY CONTROLLED” is used to control the operation of the RANGER 300 DLX output contactor. With the switch in the “WELDING TERMINALS ALWAYS ON” position, the contactor is closed at low and high idle.

When a wire feeder or TIG Module control cable is attached to either the 6 pin of 14 pin amphenol con- nector and the Welding Terminals switch is in the

“WELDING TERMINALS REMOTELY CONTROLLED” position, the contactor is open in low idle and high idle until and the wire feeder trigger or Amptrol is closed. This closes the 2-4 circuit. When the gun trigger or Amptrol is released, the contactor opens and there is no voltage present at the electrode.

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

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

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

9.WELD OUTPUT TERMINAL (TO WORK) WITH FLANGE NUT: Provides the connection point for the work cable.

10.WELD OUTPUT TERMINAL (TO ELECTRODE HOLDER) WITH FLANGE NUT: Provides the con- nection point for the electrode holder.

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 RANGER 300 D/DLX (Includes contactor closure circuit on the Ranger 300 DLX & remote control circuit).

13.14 PIN AMPHENOL (DLX Model Only): For attaching wire feeder control cables to the RANGER 300 DLX (Includes contractor closure circuit, remote control circuit, wire feeder 115/42 volt power source).

14.VOLTMETER (DLX MODEL ONLY) - Displays actual voltage at the output terminals when welding in CV- mode.
