Lincoln Electric IM10084 manual Left Display Selection, WFS Knob Range, Amperage Calibration

B-6 OPERATION B-6

LEFT DISPLAY SELECTION

The left display can show either amperage or actual WFS during welding. Note that actual WFS is not the same as preset WFS. For example, the preset WFS may be set to 400 ipm, but the arc voltage is only 15V. The actual WFS will be approximately 280 ipm because there is not enough arc voltage to run at 400 ipm.

To change the left display reading:

Rotate the WFS knob to the left to display amperage (current).

Rotate the WFS knob to the right to display actual WFS.

Then rotate the knob to the 12 oʼclock position.

Press the set-up button.

WFS KNOB RANGE

For wire feeders equipped with standard torque gear- ing, the WFS range can be changed to provide better knob sensitivity at low wire feed speeds. This is often useful when welding with Innershield™ wires.

To change the WFS knob range:

Rotate the WFS knob to the left for the low wire feed speed range of 40 – 405 ipm

Rotate the WFS knob to the right for the high wire feed speed range of 40 – 715 ipm.

Then rotate the knob to the 12 oʼclock position.

AMPERAGE CALIBRATION

Measurements for adjusting the Amperage 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 Display Hold.

While in the set-up menu, adjust the calibration factor as follows:

Power Source Amperage = Calibration Factor Example:	200 = 1.05
Feeder Amperage	210

Press the set-up button again to enter the Amperage Calibration.

Rotate the knob to the 12 oʼclock position, then press the set-up button to enter Display Hold.

DISPLAY HOLD

After welding, the LN-25 IRONWORKER will hold the last values from welding on the display. The values will continue to be displayed until the hold period is finished, the trigger is pulled again, or the cold feed/gas purge switch is activated.

To change the Display Hold time:

Rotate the WFS knob to the left for 5 seconds Hold.

Rotate the WFS knob to the right for 300 seconds Hold.

Press the set-up button to exit the set-up menu.
