The K126 Innershield Pro gun has been designed for
use with Lincoln Innershield brand self-shielded cored
wire electrodes. Refer to the appropriate Lincoln
Process and Procedure Guidelines for the electrode
used for information on recommended electrical and
visible stick outs.

1. Check that the welding power source is on.
2. Position electrode over joint. End of the electrode
should be slightly off the work.
3. Lower welding helmet, close gun trigger, and begin
welding. Hold the gun so the contact tip to work
distance gives the correct electrical stick out as
required for the procedure being used.
4. To stop welding, release the gun trigger and then
pull the gun away from the work after the arc goes
out.

Wire feeding problems can be avoided by observing the
following gun handling procedures:
1. Do not kink or pull cable around sharp corners.
2. Keep the electrode cable as straight as possible
when welding or loading electrode through cable.
3. Avoid wrapping excess cable around handle or
front of wire feeder.
4. Do not allow dolly wheels or trucks to run over
cables.
5. Keep cable clean by following maintenance instruc-
tions.
6. Use only clean, rust-free electrode. The Lincoln
electrodes have proper surface lubrication.
7. Replace contact tip when the arc starts to become
unstable or the contact tip end is fused or
deformed.
