INSTALLATION INSTRUCTIONS
(4-ROLL FEEDERS)
1. Turn off input power to the welding power source
using the disconnect switch at the fuse box before
installing the clutch drive system.
2. Remove the gun and cable, drive rolls, and guide
tubes from the feeder.
3. Remove the hex head screw, clamping collar, and
key from the drive shafts. Save these parts as they
will be required if this feeder is used for normal
operation.
4. Clean and polish the drive shaft on the outgoing
side of the gearbox using a fine abrasive cloth (400
grit). The drive roll must be able to spin freely.
5. Remove both idle rolls from the swing arms by
removing the pins and the socket head cap screws
and washers on the top and bottom of the swing
arms. Save the pins and hardware for later reuse.
(See Figure 4).
Figure 4
Note: All the parts that were removed from the feeder
should be saved. These parts are required for
normal operation. Now the system is ready to
mount all parts of the clutched drive roll system.
6. As shown in Figure 5, mount the bottom clutch pad,
the drive roll, the top clutch pad, and the spring/bolt
assembly to the feeder’s outgoing side drive shaft.
DO NOT OVERTIGHTEN THE BOLT. Only snug it
to secure the assembly. The proper tension is pre-
set for the wire size and does not need adjustment.
Make sure that the clutch material faces the drive
roll.

7. Mount the long incoming guide tube and the outgo-
ing guide tube into their respective mounts. Do not
overtighten the thumb screw as it may damage the
guide tubes.
8. Install the grooved idle roll in the outgoing side
swing arm using the pins and hardware from Step 5.
9. Mount a new Magnum gun and cable with a fresh
liner designed specifically for aluminum. Page 5
contains recommended liners and tips for standard
Magnum guns.
10. Be certain that the guide tube do not touch the
drive roll or the idle roll. If they do touch, readjust
them and tighten in place.
ELECTRIC SHOCK Can Kill
• Only qualified persons should perform
this installation.
• When inching the electrode, the drive mechanism
and the electrode may be electrically "hot".
• Dirt that accumulates on the wire can be forced into
the feeder and welding gun creating feeding resis-
tance. Maintaining a clean feeder and a clean wire
supply will minimize feeding problems.
