The pressure arm controls the amount of force the
drive rolls exert on the wire. Proper adjustment of the
pressure arm gives the best welding performance.
Set the pressure arm as follows:
(See <:HE8)
Aluminum wires between 1 and 3
Cored wires between 3 and 4
Steel, Stainless wires between 4 and 6

Loading 10 to 15 lb. (4.5 – 6.8kg) Spools.
A K468 spindle adapter is required for loading 2"
(51mm) wide spools on 2" (51mm) spindles. Use a
K468 spindle adapter for loading 2-1/2" (64mm) wide
spools.
1. Squeeze the release bar on the retaining collar and
remove it from the spindle.
2. Place the spindle adapter on the spindle, aligning
the spindle brake pin with the hole in the adapter.
3. Place the spool on the spindle and align the adapter
brake tab with one of the holes in the back side of
the spool. An indicator mark on the end of the spin-
dle shows the orientation of the brake tab. Be cer-
tain the wire feeds off of the spool in the proper
direction.
4. Re-install the retaining collar. Make sure that the
release bar snaps out and that the retaining collar
fully engages the groove on the spindle.
