Setting The Wire Spool Tension - MasterCraft 058-8194-4 Instruction Manual

4. Place the spool on the hub with the
wire passing from the bottom of spool
into the drive mechanism
Note: The welder can use either 4" or 8" spool. The 8" spool requires an adaptor. The wing nut
controls the tension on the spool.

5. Setting the wire spool tension:

a. Turn the wire spool with one hand.
b. Increase the spool tension by tightening the wing nut while turning the spool. Turn the
spool until it slows down.
c. Stop tightening the wing nut. Repeat these steps until proper spool tension is achieved.
Note: If high tension is applied to the wire spool, the wire slips on the drive roller or will not be able
to feed. If less tension is applied, the wire spool unspools itself when the trigger is released.
Readjust the spool tension using the wing nut if the tension is high or low.
6. Disconnect the welder from the power source, and remove the leading end of the wire from
the spool.
7. Cut off any bent portion of the wire using a wire cutter.
8. Loosen the tension adjusting knob holding the drive tension arm in place and lift the tension
arm up off the drive roller.
9. Insert the wire into the inlet guide tube, and feed it of about six inches across the drive roller
and into the torch assembly.
10. Line up the wire with the correct groove in the drive roller.
11. Place the drive tension arm back above the drive roller.
12. Tighten the drive tension adjusting knob until the tension roller is applying enough force on
the wire to prevent it from slipping in the drive roller.
13. Plug in and turn the welder ON. Set the voltage switch to the voltage setting recommended for
the gauge of metal that is to be welded. Refer to the set up chart on the back side of the wire
drive compartment.
