INSTALLING DRIVE ROLLS

TM
LWF™-22: One reversible drive roll needs to be installed on each LWF -22 wire feeder. Normally
each drive roll has two different size grooves for feeding different diameter wire. One groove is for
feeding 0.8/1.0/1.2mm and the other groove is for feeding 1.0/1.2/1.6mm. Ensure that the drive roll is
installed using the correct groove for the wire diameter being used.
TM
LWF™-24 PLUS: Two reversible drive rolls need to be installed on each LWF -24 PLUS wire feeder.
Normally each drive roll has two different size grooves for feeding different diameter wire. One groove
is for feeding 1.0/1.2mm and the other groove is for feeding 1.2/1.6mm. Ensure that the drive roll is
installed using the correct groove for the wire diameter being used.
Notice: make sure the specifications of the 2 symmetrical feed rolls are same. And don't make any
mistake about it!

LOADING THE WIRE SPOOL

LWF™-22
Loosen the retainer on the spindle and put on the welding wire spool. Next, replace the retainer and
tighten the screw. Release the pressure handle and lift the pressure arm, then insert the welding wire
into the inlet straightening rolls 2-3cm (1/4 – 1 inch). Now, replace the pressure arm and tighten with
the pressure handle noting that the pressure scale should suit the wire diameter. Using the cold-inch
button on the feeder, begin feeding wire. Release the cold-inch button when the wire comes out 1-2cm
(1/2-1 inch) from the contact tip. The installation of the welding wire is now completed.
