Gouging Kit
WARNING
If the wire feeder is turned on with the process switch in
the gouging position, the welding output will turn on.
The Power Feed 84 is available from the factory with the
gouging kit installed.
The gouging kit includes a mounting stud for attaching a
gouging torch and two contactors to electrically isolate
the gouging torch while welding, and to isolate the
welding head while gouging.
The contactors automatically switch from the wire drive
to the gouging stud when a gouging, stick or TIG mode
is selected. If two single wire drives with gouging kits are
connected to one power source, then only one wire drive
at a time may be selected for gouging.
The gouging kit is not available for dual wire drives.

Gas Flow Sensor Kit
The gas flow sensor uses a mass flow sensor for
measuring gas flow in the range of 0 – 28 I/min.
The gas flow sensor kit is compatible with the following
gases:
Argon
CO2
98Ar 2CO2
90Ar
10CO2
85Ar 15CO2
80Ar
20CO2
75Ar 25CO2
Dual feeders require (2) gas flow sensors
Maintenance
WARNING
Electric Shock can kill.
Turn the input power OFF at the
welding power source before
installation or changing drive rolls
and/or guides.
Do not touch electrically live parts.
When inching with the gun trigger, electrode and
drive mechanism are "hot" to work and ground and
could remain energized several seconds after the
gun trigger is released.
Do not operate with covers, panels or guards
removed or open.
Only qualified personnel should perform
maintenance work.
WARNING
For any maintenance or repair operations it is
recommended to contact the nearest technical service
center or Lincoln Electric. Maintenance or repairs
performed by unauthorized service centers or personnel
will null and void the manufacturer’s warranty.
WFS Calibration
Measurements for adjusting the WFS calibration must be
made before entering the set-up menu.
On dual feeders, there is calibration value for each wire
drive.
Wire Feed Speed offset allows the operator to adjust the
speed of the WD drive rolls. The adjustment can range
from -5% to +5% of normal speed.
On dual-head Power Feed 84 Feeders, a different set-
ting can be used for each head. The operator will be
prompted to select which head to edit before the setting
can be changed.
The calibration factor is adjustable from 0.95 to 1.05.
Adjust the WFS calibration value in the set-up menu.
While in the set-up menu, adjust the calibration factor as
Follows.
Example:
Actual WFS/Set WFS = Calibration Factory.
Example:
405/100=1.01
Routine Maintenance
Check weld cables, control cables and gas hoses for
cuts.
Clean and tighten all weld terminals
Periodic Maintenance
Clean the drive rolls and inner wire guide and replace if
worn.
Blow out or vacuum the inside of the feeder.
Inspect the motor brushes every 6 months. Replace if
shorter than 0.5” (12.7mm).
Every year inspect the gearbox and coat the gear teeth
with a moly-disulfide filled grease. DO NOT use graphite
grease.
