Recommended Outershield electrodes are: .045
(1.1mm), .052 (1.3mm) and 1/16 (1.6mm) Outershield
71 and 1/16” (1.16mm) Outershield 70. Request
Lincoln publication GS-200 for additional information.
Some recommended solid wires for MIG welding are:
.030 (0.8mm), .035 (0.9mm) and .045 (1.1mm) L-50
and L-56. Request Lincoln publication GS-100 for
additional information.
When using a wire feeder with contactor control, the
electrode will be “cold” until the gun trigger is pressed.
To start the welding process, position the gun and
close the gun trigger. The contactor will close, the arc
will be initiated and the engine will accelerate to full
speed. To stop welding, release the gun trigger and
pull the gun away from the work. With the “IDLER
SWITCH” in the “AUTO” position, the engine will go
back to low idle in approximately 12 seconds (when
no auxiliary power is drawn).
NOTE: The LN-7 and the LN-8 must be operated in
the “HIGH” idle position.
