3. TRIGGER CONNECTOR

There is one circular connector for the gun trigger on the front of the LN-25 PRO. Note – if the gun trigger is already depressed when the feeder is powered up, the feeder will not activate. Release and then press the gun trigger to begin welding.

The 83% wire feed speed reduces the wire feed speed to 83% of the original set value when activated. For example, if the original wfs = 200 in/min, the feed- er will regulate to 0.83 x 200 = 166 in/min.

The 83% trigger requires a gun with a dual procedure switch.

This feature is often useful when welding pipe, and a “cooler” procedure is required on the bottom portion.

5. SET-uP PuShbuTTON

before entering the set-up menu:

Calibration of Wire Feed Speed:

Set the display to the desired wire feed speed (example: 400 inches per minute)

Measure the actual wire feed speed (example: 405 inches per minute)

Place the WFS knob in the 12 o’clock position.

To enter the set-up menu, use paper clip to press the small button located on the case front.

PUSHBUTTON

WIRE FEED SPEED uNITS

To change the wire feed speed units:

Rotate the WFS knob to the left to use “inches/minute” for the wire feed speed units.

WFS CALIbRATION

Measurements for adjusting the WFS calibration must be made before entering the set-up menu. If no changes are being made to the calibration, then press the set-up button to enter WFS Knob Range.

While in the set-up menu, adjust the calibration factor in the following example:

Actual WFS

= Caibration Factor
