WELD-PAK 100
CHANGING DRIVE ROLL
The drive roll has two grooves; one for .023"
– .025" (0.6 mm) solid steel electrode and a
larger knurled groove for .030" (0.8 mm)
solid and .035" (0.9 mm) flux-cored steel
electrode. As shipped, the drive roll is
installed in the .030"/.035" (0.8/0.9 mm)
position.
If .023" – .025" (0.6 mm) wire is to be used,
the drive roll must be reversed as follows:
1. Connect the machine to its rated input
power per instructions in Installation sec-
tion.
2. Release the spring-loaded pressure arm
and lift the idle roll arm away from the
drive roll.
3. Turn the power switch to ON (marked
“I”).
4. Set the wire speed to minimum and jog
the drive unit with the trigger switch until
the drive roll set screw is facing up.
When inching the welding wire, the drive
rolls, gun connector block, and gun con-
tact tip are energized relative to work
and ground and remain energized for
several seconds after the gun trigger is
released.
5. Turn the power switch to OFF (marked
“O”).
6. Loosen the drive roll set screw with the
5/64" (2.0 mm) hex wrench supplied.
7. Remove the drive roll, flip over and rein-
stall with the .023 – .025" (0.6 mm)
groove (the smaller groove) closest to the
gearbox.
8. Push a length of straightened welding
wire through the wire feeder guide tubes
and adjust the position of the drive roll so
that the groove is centered on the wire.
Make certain the set screw is located on
the flat portion of the shaft and tighten.
