5 Jam Nut
Remove top jam nut from switch
(switch is equipped with two nuts, a
jam nut and a backing nut).
Insert switch shaft through center
panel. Switch should be positioned
so lead with resistor is facing down.
Secure switch to center panel with
jam nut. Tighten jam nut enough to
keep switch from rotating.
6 Spoolgun Switch Plug
Locate matching spoolgun recep-
tacle in wiring harness, and remove
jumper plug. Keep jumper plug in
case spoolgun switch is removed.
Connect spoolgun switch plug to
receptacle.
Reinstall wrapper.
Operation:
Place switch in On position for
spoolgun operation. Place switch in
Off position for wire feeder/MIG
(GMAW) gun operation.
When spoolgun switch is in On
position, spoolgun wire feed speed
is controlled by welding power
source Wire Speed control.
