6. Turn the Feed Tensioner counterclockwise to

loosen it enough to pull it up, releasing tension.

Swing the Feed Swing Arm out.

Note: Do not loosen the Feed Tensioner

too much, or it will come apart.

7.

Loosen and remove the Feed Knob. Compare

the wire diameter marked on the Wire Spool with

the stamped number on the top of the Feed Roller.

The Roller’s groove size must be compatible with

the wire diameter. Flip the Feed Roller as needed

and confirm that the number facing up is the same

as the wire diameter on the Spool.

Replace and secure the Feed Knob.

IMPORTANT:

Securely hold onto the end of the welding wire and

keep tension on it during the following steps.
If this is not done, the welding wire will unravel

and create a tangled “bird’s nest”, wasting wire.

8. Cut off all bent and crimped wire.

Make sure that the cut end has no burrs

or sharp edges; cut again if needed.

9. Keep tension on the wire and guide at least

12 inches of wire into the Wire Liners.

10. Swing the Feed Swing Arm closed, and swing

the Feed Tensioner across the tip of the Arm, to

latch it. Make sure the Welding Wire is resting in

the top groove of the Feed Roller, then turn the

Feed Tensioner clockwise a couple of turns.

After the wire is held by the Feed

Tensioner, you may release it.

11. Pull the Nozzle to remove it.

12. Turn the Contact Tip

counterclockwise and remove.

13. Lay the Gun Cable out in a straight line so that the

wire moves through it easily. Leave the cover open,

so that the feed mechanism can be observed.
