Lincoln Electric IM511-D manual Summary Of Welding Process

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.
