Use care in handling the spooled wire as it

will tend to “unravel” when loosened from the

spool. Grasp the end of the wire firmly and do

not let go of it. Make sure that the end of the

wire is free of any burrs and is straight.

Route the wire Through the Feedhead

1. Loosen Pressure Adjust Device (Fig. 3-9).
2. Open Pressure Adjust Device (Fig. 3-9).
3. Open Pressure Arm (Fig. 3-9).
4. Place the end of the wire into the Inlet Wire Guide,

feeding it over the Feedroll. Make certain that the proper

groove is being used (Fig. 3-10).
5. Pass the wire into the Gun Liner of the Gun Cable End

(Fig. 3-10).
6. Close the Pressure Arm (Fig. 3-10).
7. Close the Pressure Adjust Device. Tighten it to a “snug”

condition (Fig. 3-10).

If there is too much pressure on the drive roll

the wire gets locked and the motor could get

damaged, If it is too loose the wire will not

feed properly.
