IMPORTANT:

SAFETY

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.

SETUP

9.

Cut off all bent and crimped wire.

 

The cut end must have no burrs or

 

sharp edges; cut again if needed.

 

 

 

10.

Keep tension on the wire and guide at least

 

 

12 inches of wire into the Wire Liners.

WELDING

11.

Swing the wire feed swing arm down, and swing

 

the feed tensioner up to latch it across the tip of

 

the arm. Make sure the Welding Wire is resting in

 

the bottom groove of the Feed Roller, then turn the

 

 

 

 

feed tensioner knob clockwise a couple of turns.

 

 

After the wire is held by the tensioner,

 

 

you may release it.
