DRIVE ROLLER ADJUSTMENTS
The drive roller has two grooves built
into it for different wire sizes. The
correct wire size number is stamped on
each side of the drive roller. The number
facing you when installing the drive
roller must match the wire size. Use only
the proper size drive roller when using your welding unit.
Table 1 indicates which drive roller groove should be used with each wire
diameter size.
1. Find the side of the drive roller (Fig. 3-1) that is
stamped with the same wire diameter (Fig. 3-2)
as that of the wire being installed. Push the
drive roller onto the drive roller motor shaft
(Fig. 3-3), with the side stamped with the
desired wire diameter facing you.
2. Reinstall the drive roller cap (Fig. 2-4) and lock
in place by turning it clockwise.
3. Close the door to the welding unit drive compartment.
