Selection of drive rolls and guide tubes

WARNING!
When the wire feeder is connected to the power source, the work lead from the
power source is connected to the workpiece and the power source is energized.
Closing the torch trigger will cause the welding wire to become electrically hot
and will cause the drive rolls to turn. Keep fingers clear!
The drive rolls have two grooves. The unit is supplied ready to feed 0.045", .052" or 1/16"
(1.2 to 1.6 mm) diameter cored wires or .035" - .045" (0.9 - 1.2 mm) hard wires depending on
the part number ordered.
Other drive rolls are available to feed other sizes of hard wire, soft wire, and cored wire. See
Drive Roll and Guide Tube Selection Chart in the WEAR PARTS chapter.
Two lower drive rolls are required for four-roll drive systems.
