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.
OPERATION
POWER-UP SEQUENCE
All of the LED's will briefly illuminate during power-up.
If the gun trigger is activated during power up, the
(See Figure B.1)
feeder will not operate until the gun trigger is released.
