Right Way
Figure 6. Wire Installation
. If you are installing a four-inch spool of wire, install the drive brake hardware on the top of the spool of wire according to figure 7A. If you are installing an eight- inch spool, install the spindle adapter and drive brake hardware as shown in Figure 7B. The purpose of the drive brake is to cause the spool of wire to stop turning at nearly the same moment that wire feeding stops.

6.Once the drive brake hardware is installed, set the spool tension. With one hand, turn the wire spool and continue turning it while adjusting the tension on the spool. With your free hand, tighten (tum clockwise) the knob that holds the spool in place. Stop tightening when drag is felt on the wire spool that you are turning, then stop hand- turning the wire spool.
Note: If TOO MUCH tension is applied to the wire spool, the wire will slip on the drive roller or will not be able to feed at all. If TOO LITTLE tension is applied, the spool of wire will want to unspool itself. Readjust the drive brake tension as necessary to correct for either problem.
7.After checking to make sure that your welder is disconnected from the ac power source, free the leading end of the wire from the spool, but do not let go of it until told to do so, or the wire will unspool itself.
8.Use a wire cutter, cut the bent end off the leading end of the wire so that only a straight leading end remains.
9.Loosen the tension adjusting screw holding the drive tension arm in place and lift the tension arm up off the drive roller.
10.Insert the leading end of the wire into the inlet guide tube. Then push it across the drive roller and into the gun assembly about six inches.
CAUTION
Make certain that the welding wire is actually is going into the gun liner. Be very sure it has not somehow been accidentally been routed alongside the liner or even in some other direction. If this should happen, the wire could feed inside the cable casing or take a right angle and follow the wires and gas hose inside the welder. It could also feed back on itself jamming up the mechanism.
11.Line the wire up in the inside groove of the drive roller, then allow the drive ten- sion arm to drop onto the drive roller.
12.Tighten (turn clockwise) the drive tension adjusting screw until the tension roller is applying enough force on the wire to prevent it from slipping out of the drive assembly.
13.Let go of the wire.
14.Connect the welder power cord to the ac power source. Turn the welder ON by setting the VOLTAGE switch to the volt- age (heat) setting recommended for the gauge metal that is to be welded. Refer to the label mounted on the cover, inside the drive compartment, for recommended voltage (heat) settings for your welding
