13. WELD MODE SELECTOR SWITCH:

(Provides 3 selectable welding modes)

CV-WIRE

CC-STICK

TOUCH START TIG

14. ARC CONTROL:

The ARC CONTROL WIRE/STICK knob is active

in the WIRE and STICK modes, and has different

functions in these modes. This control is not

active in the TIG mode.

CC-STICK mode: In this mode, the ARC CON-

TROL knob sets the short circuit current (arc-

force) during stick welding. Increasing the num-

ber from -10(Soft) to +10(Crisp) increases the

short circuit current and prevents sticking 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

CV-WIRE mode: In this mode, turning the ARC

CONTROL knob from -10(soft) to +10(crisp)

changes the arc from soft and washed-in to crisp

and narrow. It acts as an inductance/pinch con-

trol. The proper setting depends on the proce-

dure and operator preference. Start with a setting

of 0.

15. WELDING TERMINALS SWITCH:

In the WELD TERMINALS ON position, the out-

put is electrically hot all the time. In the

REMOTELY CONTROLLED position, the output

is controlled by a wire feeder or amptrol device,

and is electrically off until a remote switch is

depressed.

WARNING

• There is no VRD protection in the CV Mode.

• When the Toggle switch is in the "WELD

TERMINAL ON" position the voltage at the

output terminal maybe up to 60V.

16. WIRE FEEDER VOLTMETER SWITCH:

Matches the polarity of the wire feeder volt-

meter to the polarity of the electrode.

OPERATION

17. 6 - PIN CONNECTOR:

For attaching optional remote control equipment.

When in the CC-STICK and CV-WIRE modes

and when a remote control is connected to the

Connector, the auto-sensing circuit automatically

switches the OUTPUT control from control at the

welder to remote control.

18. 14-PIN CONNECTOR:

For attaching wire feeder control cable. Includes

contactor closure circuit, auto-sensing remote

control circuit, and 42VAC or 115VAC power.

The remote control circuit operates the same as

the 6-Pin Connector.

19. 42V / 115V WIRE FEEDER VOLTAGE

SWITCH:

Toggles output of 14-pin connector to voltage

requirement of Wire Feeder. (Located above 14-

pin connector.)

20. WELD OUTPUT TERMINALS + AND -

These 1/2" - 13 studs with flange nuts provide

welding connection points 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 con-

nects to the "+" terminal and the electrode cable

connects to this "-" terminal.
