LN-25 INSTRUMENTS AND CONTROLS

Refer to Figure B.1 for control locations.

NOTE:

1. The Voltmeter will read zero if the LN-25 work

clip lead is not connected to work, even if the

electrode is electrically “hot” to work.

2.

The Voltmeter will read below zero if the LN-25

 

polarity switch is not set to the same polarity as

 

the electrode.

3.

The Voltmeter will read power source open

 

circuit voltage when the gun trigger is open, even

 

if the LN-25 is equipped with the internal

 

contactor.

“ELECTRODE POLARITY” SWITCH

The polarity switch is located on the front panel of the LN-25 case.

Set the switch to the same polarity as the electrode lead connection to the power source. If the switch is not set for the correct polarity, the wire feeder will not operate.

WIRE FEED MODE SWITCH

The CV-VV (CC) Wire Feed Mode switch is located inside the LN-25 case. The toggle switch extends from beneath the control box just above the wire drive.

The forward “CV” position provides constant wire feed speed mode for use with constant voltage (CV) welding power sources.

The backward “VV (CC)” position provides arc-sensing wire feed speed mode for use with constant current (formerly variable voltage) welding power sources.

WIRE SPEED DIAL AND RANGE SWITCH

The Wire Speed control dial on the front panel of the LN-25 has two calibrated dial ranges selected by the HI-LO Dial Range switch.

VOLTMETER

(Factory installed on model Codes above 9218)

The 40V DC analog voltmeter is mounted to the front control panel of the LN-25 and is connected to read the arc voltage between the LN-25 electrode cable connection and the work clip lead.

When switched to the LO range position, the constant wire feed speed (CV Wire Feed Mode) is set on the inside (white) dial range calibrated for 50 to 350 in/min.

When switched to the HI range position, the constant wire feed speed (CV Wire Feed Mode) is set on the outside (black) dial range calibrated for 50 to 700 in/min.

The volts marks around the HI range calibrated dial indicate the minimum arc volts required to obtain the indicated HI range wire feed speeds. For example; if
