Firepower MST 180i

3.13 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 3-9.
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.
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.
