83% FUNCTIONALITY (for Innershield®
Pipeline welding)
With a special Gun, the LN-25™ Pro incorporates
83% functionality. This feature allows for the reduction
of the wire feed speed to 83% of the original set value
when activated with a second switch (usually in the
gun). The 100% wire feed is adjusted using the wire
feed speed knob on the front of the machine, and is
displayed on the right LED. When the reduced wire
speed switch (mounted on the gun handle) is in
Position No. 1, the wire speed feed will be that figure
indicated on the display. In Position No. 2, the wire
feed speed will be 83% of the figure indicated on the
display.

7. THERMAL LED
Thermal LED, Motor Overload The
thermal light illuminates when the wire
drive motor draws too much current. If
the thermal light illuminates, the wire
drive will automatically shutdown for up
to 30 seconds to allow the motor to cool. To start
welding again, release the gun trigger, inspect the
gun cable, liner (and conduit). Clean and make
repairs as necessary. Start welding again when
the problem has been safely resolved.
For best results, keep the gun cable and conduit as
straight as possible. Perform regular maintenance
and cleaning on the gun liner, conduit and gun.
Always use quality electrode, such as L-50 or L-56
from Lincoln Electric.
