Prince™ XL/Spool Gun - Owner's Manual Page 7
Introduction
This manual details the installation and operation of your Prince
TM
XL Torch,
and Prince
TM
XL Spool Gun.
These torches have 7 pin “W” clocked amphenol connectors and are de-
signed for use with Cobramatic cabinets model numbers 150-003, 150-004,
150-203 and 150-204. To use these torches on older style cabinets with
plastic doors (MK3A, MK3A PS) , a 7 pin “W” clocked amphenol kit, P/N 005-
0162, must be used.
A variety of Weld Control Boxes are available to adapt the Prince™XL spool
gun to the power source you are using (see section 34 & 35 for details). A
secondary Contactor Box (P/N 001-3066), is also available for those power
supplies not having there own contactor. Consult the Weld Control Selector
Guide (P/N 091-0458) for various welding equipment interfacing.
The Prince™XL and Prince™XL Spool Gun bodies are identical except for
the lead assemblies and spool portion.
The Prince™XL utilizes our patented EZ Lock™ design which allows the
operator to remove or rotate the barrel without the use of tools.
The Prince™XL air cooled version comes standard with a straight air cooled
barrel assembly (P/N 003-1980) and uses the same contact tips and gas
cups as the MK Cobra® Gooseneck torch. A rotating air cooled barrel
assembly (P/N 003-1986) is available as a spare part.
The Prince™XL water cooled version comes standard with a straight water
cooled barrel assembly (P/N 003-1973) and uses the same contact tips, cups
and adapter as the King Cobra® torch. A rotating water cooled barrel assem-
bly (P/N 003-1987) is available as a spare part.
The wire speed control knob is located on the bottom of the torch handle and
provides 3-3/4 turns of rotation, with a maximum speed of 900 ipm.
An important feature of the Prince™XL spool gun assembly is that it can be
converted from a spool gun into a Push-Pull system to be used with the
Cobramatic® Cabinet. Simply remove the spool assembly and wire guide
adapter and liner, and install a conduit of the appropriate length. The power
lug on the power cable assembly can be attached to the upper hole on the
power block assembly in the Cobramatic® Cabinet. Remove the hole plug
and secure cable assembly using a hex head screw 3/8” - 16 x 3/4 (P/N 329-
0055) and a flat washer 1/2” (P/N 331-0176).
The Prince™ XL Spool gun assembly has been redesigned to improve and
simplify the spool drag tension settings. By eliminating the guesswork of
setting the correct drag tension, the operator can now focus on the actual
welding. The new “patented” brake assembly automatically self-adjusts to the
ever-changing spool tension as the coiled wire is reduced in diameter off the
spool. The new brake assembly maintains the wire “level on the spool” and
prevents unspooling and potential wire
entanglements.
This new brake assembly can be installed onto any existing Prince™ XL gun
and can be used in place of the existing spool kit assemblies. No parts of the
new kit can be used with the old kit or existing handles. The new spool kit (P/
N 005-0632) includes new handles, trigger, trigger pin, all handle screws and
spool assembly. See Optional Kits on page 7 for part numbers for these two
new kits.
