Prince™ XL/Spool Gun - Owner's Manual Page 17
16.3 Potentiometer
The pot is located in the bottom of the pistol grip and provides 3-3/4 turns of
rotation and up to 900 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.
16.4 Micro Switch
The micro switch assembly (P/N 003-0568) consists of the micro switch,
leads, and connector. The assembly is secured to the torch block with two(2)
screws. An insulator between the torch block and micro switch prevents
accidential shorting of the switch leads. The leads are laid in the channel
under the motor and held in place with electrical tape.
16.5 Lead Assemblies
16.5.1 Power Cable - Air Cooled
A #2 AWG power cable is used on the Prince™XL air cooled torch. The torch
end is threaded into the torch body. The power cable fitting connects to the
Power Block
(P/N 003-1674) when using a Cobramatic® wire feed cabinet. When the
Prince™XL is purchased as a Spool Gun, the power cable comes standard
with a lug connector.
16.5.2 Power Cable - Water Cooled
Prince™XL water cooled torch utilizes a power/water cable with a #4AWG
cable inside a 5/8” (16MM) diameter hose. When water is used with this
cable and the #10 water cooled gas cup is used (P/N 621-0065), the system
is rated at 400 amps 100% duty cycle. If water is not used with this cable, the
system is rated at 100 amps 50% duty cycle.
16.5.3 Conduit
The Prince™XL Torch comes standard with a poly lined conduit, for running
aluminum wire. The longer fitting with a shallow groove is used on the torch
end. A set screw located on top of the torch handle secures the conduit in
place. A small spool liner (P/N 003-0198) is used on the spool gun and held
in place by the same set screw.
16.5.4 Gas Hose
The gas hose is secured over the barbed gas fitting with a tie wrap. The
cabinet end of the gas hose uses our standard gas fitting (1/8” - 27 nps),
whereas the spool gun uses a 5/8” - 18 IAA RH male gas fitting.
16.5.5 Water Hose
The water hose (if so equiped) is secured over the barbed water fitting with a
tie wrap.
16.5.6 Electric Cable
A seven conductor control cable is used on the Prince™XL Torch. The torch
end of the control cable is secured to the torch with a boot clamp and plugged
into the pot assembly and micro switch connectors. Slack is left in the electric
cable as it exits the back of the torch to prevent cable breakage. The cabinet
end has a seven pin "W" clocked amphenol connector. See page 17 for torch
electrical connections.
