3.09 Installing Handispool (200mm diameter)
As delivered from the factory, the unit is set for a Handispool (200mm diameter).
In order to re-fit a 200mm spool assemble parts in the sequence shown below in Figure 3-7.
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 10 to 20mm
(measured at the outer edge of the spool) after Mig Torch 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
componentry 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 the
Handispool.
NOTE
This alignment pin can be removed by unscrewing in an anticlockwise direction and locating in
the appropriate position.
