CONNECTION OF LN-15 TO THE COM- MANDER 300

These connections instructions apply to both the LN- 15 Across-The-Arc and Control Cable models. The LN- 15 has an internal contactor and the electrode is not energized until the gun trigger is closed. When the gun trigger is closed the wire will begin to feed and the welding process is started.

•Shut the welder off.

•For electrode Positive, connect the electrode cable to the "+" terminal of the welder and work cable to the "-" terminal of the welder. For electrode Negative, connect the electrode cable "-" terminal of the welder and work cable to the "+" terminal of the welder.

•Across-The-Arc Model:

Attach the single lead from the front of the LN-15 to work using the spring clip at the end of the lead. This is a control lead to supply current to the wire feeder motor; it does not carry welding current.

Control Cable Model:

Connect Control Cable between Engine Welder and Feeder.

•Set the MODE switch to the "CV-WIRE " position.

•Across-The-Arc Model:

Set the "WELD TERMINALS" switch to "WELD

TERMINALS ON"

Control Cable Model:

Set the "WELD TERMINALS" switch to

"REMOTELY CONTROLLED"

•Set the "WIRE FEEDER VOLTMETER" switch to either "+" or "-" as required by the electrode polarity being used.

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

CONNECTION OF AN NA-3 AUTOMATIC WELDING SYSTEM TO THE COMMANDER 300

For connection diagrams and instructions for connect- ing an NA-3 Welding System to the Commander 300, refer to the NA-3 Welding System instruction manual. The connection diagram for the LN-8 can be used for connecting the NA-3.

CONNECTION OF AN LN-742 TO THE COMMANDER 300 (FOR CODES ABOVE 10500 ONLY) (Requires optional K1597-1, 42 VAC

Transformer Kit).

•Shut the welder off.

•Connect the LN-742 per instructions on the appro- priate connection diagram in the DIAGRAMS sec- tion.

•Set the “WIRE FEEDER VOLTMETER” switch to either “+” or “-” as required by the electrode being used.

•Set the “SELECTOR” switch to the “CV-WIRE” posi- tion.

•Adjust the “ARC CONTROL” knob to desired Crispness. SOFT for MIG and CRISP for Innershield.

•Set the “WELDING TERMINALS” switch to the “REMOTELY CONTROLLED” position.

•Set the “IDLE” switch to the “AUTO” position. When not welding, the Commander 300 engine will be at the low idle speed.
