ALIGN AND SET THE DRIVE ROLLER
The correct drive roller grove must be set on the wire drive mechanism before
the welding wire is installed in the unit.
1.
Open the door to the welding unit' s drive compartment.
2.
Remove the drive tension by loosening the drive tension adjusting knob
(Fig. 2-1) and lifting the drive tension adjustor away from the drive tension
arm (Fig. 2-2). Pull the drive tension arm away from the drive roller.
3.
If there is a wire already installed in the welding unit, roll it back onto the
wire spool by hand-turning the spool counterclockwise. Be careful not to
allow the wire to come out of the rear end of the inlet guide tube (Fig. 2-3)
without holding onto it or it will unspool itself. Put the end of the wire
into the hole on the outside edge of the wire spool and bend it over to
hold the wire in place. Remove the spool of wire from the drive
compartment of the welding unit.
4.
Rotate the drive roller Cap (Fig. 2-4) counterclockwise and remove it from
the drive roller.
5.
Pull the drive roller off the drive roller shaft.
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.
