Raise wire retainer bar to latched position.
Install wire spool onto spindle hub so that wire feeds from bottom of spool
towards slave motor. Make sure that the hole in the wire spool aligns with
pin on spindle hub. The white dot on the end of the spindle hub will aid in
this alignment.
Replace the spool retainer nut.
Lower the wire retainer bar onto the spool.
Wire Spool Drag Setting
NOTE:
Standard factory setting of the Spindle Tension Knob is set for All
Other Wires.
There are two visible position settings for this Knob, IN - All Other Wires
(Fig. 1) and, OUT - .030”/.035” Al Only (Fig. 2). The Spindle Tension Knob
must be set to match the Wire Size Selector Switch on the Cobramatic
®
front
panel.
To change this setting, it is easier done without the spool of wire on the spin-
dle. Remove the wire spool retainer nut and re-install it reversed back onto
the Spindle Tension Knob (Fig. 3). In the “Tool Mode”, the square shaped
end of the retainer fits onto the Knob. Grab the retainer nut and turn in the
COUNTER-CLOCKWISE direction until it stops. The Knob is now set to the
OUT position (.030”/.035” AL Only).
To reset the Knob back to the factory setting of All Other Wires, use the
retainer nut as described above, and turn in the CLOCKWISE direction until
it stops. The Spindle Knob is now set to the IN position. Turning the retainer
nut and Spindle Knob in this direction may require more effort, since turning
CLOCKWISE is working against a spring.
Load wire spool onto spindle according to the previous instructions.
Replace the spool retainer nut.
Lower the wire retainer bar onto the spool.
