MIG Wire , Gun Connection , Power Source and Wire Feeder Information
For smooth wire feeding, free of jamming and slipping, the drive rolls must be sized correctly. You must select the proper type and size of drive roll for the size
and type of wire used. The size of the wire and the type of drive roll is marked on the side of the drive roll. On this welder, the groove on the same side of the
printed size is the groove that corresponds to the marked size. This means that when installed, the size of the groove will always be facing in. You may need to
remove the drive roller to verify the correct groove size is being used.
Only the bottom drive roll need to be changed. The top drive roll holds pressure and is flat.
The top drive roll is not removeable.
IMPORTANT: Do not mix drive roll types or drive roll sizes, or attempt to operate with a single pair. Always use both drive rolls, matched in size and type.
The type of wire dictates the groove type:
•
Steel and Stainless (INOX) wire uses a V
-
shaped groove milled into the drive roll. This will be signified by a winged
“
V
”
stamped on the side of the drive roll, next
to the wire diameter marking.
•
Aluminum wire uses a U
-
shaped groove milled into the drive roll. This will be signified by a U mark stamped on the side of the drive roll, next to the wire diame-
ter marking. This cushions the wire, and prevents scoring and damage for easy feeding when using a polymer type gun liner.
•
Flux
-
Cored/Dual Shield wire uses a serrated groove milled into the drive roll. When viewed from the top, the appearance of the groove is similar to a closed
zipper, or saw blade. This also has a zig
-
zag marking on the side of the drive roll next to the wire diameter marking.
These drive rolls may be stamped in metric wire sizes, or in both metric and imperial sizes. To avoid confusion, use the following conversion to select the proper
drive roll for the wire diameter being used.

To change or flip the drive rolls:
•
Release both tensioners by flipping the tensioners down and towards you. The upper drive roll arms should raise.
•
Remove the thumb screws securing the lower drive rolls. (Turn Counter
-
Clockwise)
•
Remove the drive rolls and flip the drive rolls over or replace them, making note of the size. The size of the drive roll is printed on the same side as the corre-
sponding groove. The size will be turned to the inside on OEM drive rolls. Remove the drive roll to verify the size.
•
Make sure the shaft key is retained on the shaft. If necessary, use a tiny bit of lubricating grease or petroleum jelly to hold key on inner shaft.
To reinstall the drive rolls:
•
Line up each drive roll keyway with the locating key on the shaft assembly.
•
Reassemble in reverse order and tighten each roller.
•
Be sure to raise and retention drive rolls. (Suggest starting tension is around 4 to 4.5)
M
ake sure the locating keys are in place and have not pushed or slipped out of their grooves during assembly. Lightly coat the inner mating surfaces with light
machine oil if necessary to prevent future seizure. Do not lubricate the surfaces of the drive rolls or erratic feeding may result.
