Installing 8" (200Mm) Diameter Spool - Firepower MST 180i Operating Manual

3.14 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 3-10.
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 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.
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.
This alignment pin can be removed by unscrewing in an counterclockwise direction and locating in the appropriate
position.
