3. TRIGGER CONNECTOR
There is one circular connector for the gun trigger on
the front of the RED-D-ARC LN25™ PRO EXTREME.
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 weld-
ing.
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.
