The Prince™XL torch maintains a constant, steady, uniform wire feed speed,
regardless of curved or looped wire conduit. The constant push exerted by
the slave motor in the cabinet, combined with the pull of the torch motor,
causes the wire to literally fl oat friction-free through the wire conduit. The
24VDC torch motor is controlled by a 3-3/4 turn potentiometer in the torch
handle.

EMOVAL AND INSTALLATION
To remove a barrel assembly, loosen the patented EZ Lock™ Taper lock
nut assy MK P/N 003-2572 (see page 22, item 1) 3/4 to 1 turn. This will
push barrel away from the body far enough so that it may be pulled out of
the body.
To replace a barrel assembly, take care not to damage the “O” rings when
inserting into the body. Open the drive and idler roll door and seat the
barrel assembly until the inlet guide is almost touching the drive and idler
roll and the rear face of the barrel is fl ush with the aluminum body block
(see diagram). Tighten taper lock nut assembly fi rmly so that barrel cannot
rotate.

The pot is located in the bottom of the pistol grip and provides 3-3/4 turns
of rotation and up to 750 ipm.
The pot is mounted to one side of a PC board and is held in place by a
support plate; both of which have slots that locate and secure the pot in
the handles. The other side of the PC board houses the motor connectors
and ribbon cable. Locking disks behind the pot knob provides a stop at the
minimum and maximum pot settings.
