1. WIRE FEED SPEED KNOB
Use the Wire Feed Speed Knob to adjust the rate
of wire feed speed.
WFS range:
50 to 800 ipm
Because the wire feeder is powered by the arc
voltage, the full range of wire feed speed may not
be available at low voltages.

See "Constant Current Operation" for setting
the Wire Feed Speed when in the CC mode.
There is one circular connector for the gun trigger
on the front of the ACTIV8™. 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 welding.
Always turn power off at the welding power source
before moving the work lead.
The work lead attaches to the item being welded.
The thermal LED illuminates when the wire drive
motor draws too much current. If the thermal light
illuminates, the wire drive will automatically shut-
down for up to 30 seconds to allow the motor to
cool. To start welding again, release the gun trig-
ger, inspect the gun cable, liner (and conduit).
Clean and make repairs as necessary. Start weld-
ing again when the problem has been safely
resolved.
For best results, keep the gun cable and conduit
as straight as possible. Perform regular mainte-
nance and cleaning on the gun liner, conduit and
gun. Always use quality electrode, such as L-50
or L-56 from Lincoln Electric.
The polarity LED illuminates when the wire feeder
is connected to positive polarity.
