Installing 4" (100Mm) Diameter Spool; Installing 8" (200Mm) Diameter Spool - ESAB fabricator 141i Service Manual

4.04 Installing 4" (100mm) Diameter Spool

As delivered from the factory, the Power Source is fitted with a Wire Spool Hub which accepts a 8" (200mm) diameter spools. In
order to fit a 4" (100mm) diameter spool assemble parts in the sequence shown below in Figure 4-8.
Adjustment of the nut with nylon insert will control the MIG Wire Spool Brake. Clockwise rotation of this nut with nylon insert
tightens the brake. The brake is correctly adjusted when the spool stops within 4" (100mm) to 8" (200mm) (measured at the outer
edge of the spool) after MIG Gun trigger is released. Wire should be slack without becoming dislodged from the spool.
CAUTION
!
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of
electrical components and possibly an increased incidence of electrode wire Burnback into
contact tip.

4.05 Installing 8" (200mm) Diameter Spool

As delivered from the factory, the Power Source is set for a 8" (200mm) diameter spool.
In order to re-fit a 8" (200mm) spool assemble parts in the sequence shown below in Figure 4-9.
Adjustment of the nut with nylon insert will control the MIG Wire Spool Brake. Clockwise rotation of this nut with nylon insert tight-
ens the brake. The Brake is correctly adjusted when the spool stops within 3/8" (10mm) to 3/4" (20mm) (measured at the outer
edge of the spool) after MIG Gun trigger is released. Wire should be slack without becoming dislodged from the spool.
CAUTION
!
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of
electrical components and possibly an increased incidence of electrode wire Burnback into
contact tip.
Ensure that the alignment pin on the wire spool hub aligns with the hole allocated in 8"
(200mm) diameter spool.
NOTE!
This alignment pin can be removed by unscrewing in an counterclockwise direction and locating in the
appropriate position.
