CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

WARNING

Shut off welder before making any electrical connec- tions.

------------------------------------------------------------------------

CONNECTION OF THE LN-25 TO THE COMMANDER 500

The LN-25 with or without an external contactor may be used with the Commander 500. See the appropri- ate connection diagram in the DIAGRAMS section.

NOTE: The LN-25 (K431) Remote Control Module and (K432) Remote Cable are not recommended for use with the Commander 500.

•Shut the welder off.

•For electrode Positive, connect the electrode cable from the LN-25 to the “+” terminal of the welder and work cable to the “-” terminal of the welder. For elec- trode Negative, connect the electrode cable from the LN-25 to the “-” terminal of the welder and work cable to the “+” terminal of the welder.

•Attach the single lead from the front of the LN-25 to work using the spring clip at the end of the lead. This is a sense lead to supply current to the wire feeder motor; it does not carry welding current.

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

•Set the “WELDING TERMINALS” switch to “WELD TERMINALS ON”

•Adjust the “ARC CONTROL” knob to desired crisp- ness. Generally, welding is best if the “ARC CON- TROL” is set to SOFT for MIG and CRISP for Innershield. You may however, want to start in the middle and adjust (as needed) from there.

•Set the “IDLE” switch to the “AUTO” position. When not welding, the Commander 500 engine will be at the low idle speed. If you are using an LN-25 with an internal contactor, the electrode is not energized until the gun trigger is closed.

CAUTION

If you are using an LN-25 without an internal contactor, the electrode will be energized when the Commander 500 is started.

------------------------------------------------------------------------

h.When the gun trigger is closed, the current sensing circuit will cause the Commander 500 engine to go to the high idle speed, the wire will begin to feed and the welding process started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed.

CONNECTION OF LN-7 OR LN-8 TO THE COMMANDER 500

•Shut the welder off.

•Connect the LN-7 or LN-8 per instructions on the appropriate connection diagram in the DIAGRAMS section.

•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 “HIGH” position. When not welding, the Commander 500 engine will be at the low idle speed.
