LN™-15 POWER-UP SEQUENCE

NORMAL POWER-UP DISPLAY

When power is first applied to the LN™-15, the dis- play will momentarily show set-up information. For example, it may show "CV" and "HI", indicating oper- ation from a CV power source and the wire drive is configured for the high speed gear. Because of limita- tions in the display, "CV" will appear as "Cu".

After a brief moment, the LN™-15 will then display the WFS and "---". No voltage is displayed until the trigger is pressed.

Preflow:

Postflow:

Burnback:

3.Activate and then release the GAS PURGE switch to select the timer. The time will then display in the right hand side of the display. Example:

4.Rotate the WFS knob to adjust the time to the new setting.

WFS

PREFLOW, POSTFLOW AND BURNBACK TIMES

Preflow, Postflow and Burnback times are all adjustable on the LN™-15. The LN™-15 is factory set with all the times set to 0.0 seconds.

•The burnback time is adjustable from 0.00 to 0.25 seconds.

•The preflow time is adjustable from 0.0 to 25.0 sec- onds.

•The postflow time is adjustable from 0.0 to 25.0 sec- onds.

CHANGING PREFLOW, POSTFLOW OR BURNBACK TIMES:

1.Enter the “Press Spin” Set-Up Mode:

While the power to the LN™-15 is off, activate and hold the GAS PURGE switch (Down Position). Turn on power to the LN™-15, and continue to hold the GAS PURGE switch until the LN™-15 dis- plays "Press Spin". Release the GAS PURGE

switch. The LN™-15 is now in the "Press Spin" set- up mode. If after 15 seconds no other action is taken, the LN™-15 will then revert to normal oper- ation.

2.Rotate the WFS knob until the desired timer is dis- played.

5.Press the GAS PURGE switch again to save the setting. The LN™-15 will then return to the original "Press Spin" mode in step 1.

6.To exit the "Press Spin" set-up mode, turn off power to the LN™-15, or simply wait 15 seconds and the LN™-15 will enter normal operation.

WELDING MODE CV/CC MODE AND WFS UNITS

The CV/CC mode and WFS units are all readily changed during the power-up sequence. The LN™-15 is factory set for "CV" welding power sources and "inches per minute" for the wire feed speed units.

•The CV/CC mode is selectable for either CV for Constant Voltage power sources and CC for Constant Current power sources. Use CV power sources when making critical welds.

•The WFS units is selectable for either in/min and m/min.

CHANGING THE CV/CC MODE, OR WFS UNITS:

1.Enter the “Press Spin” Set-Up Mode:

While the power to the LN™-15 is off, activate and hold the GAS PURGE switch (Down Position). Turn on power to the LN™-15, and continue to hold the GAS PURGE switch until the LN™-15 displays "Press spin". Release the GAS PURGE switch.
