place. A small spool liner (MK P/N 003-0198) is used on the spool gun and
held in place by the same set screw.
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.
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 22 for torch electrical connections.
INSTALLING SPOOL ASSEMBLY (P/N 003-2090)
Loosen the screw that secures the conduit through access hole located on
top right rear handle with a 1/16" Allen wrench.

Hold brake assembly back towards top of gun, load spool onto shaft with
wire coming off the bottom of the spool. Release brake assembly to rest
on wire surface.
Replace spool cover, making sure opening is over liner.
Note:
The brake paddle assembly is designed to automatically control spool drag and
keep the wire from jumping off the spool.

the slave motor in the cabinet, combined with the pull of the torch motor,
causes the wire to literally float friction-free through the wire conduit. The
24VDC torch motor is controlled by a 3-3/4 turn potentiometer in the torch
handle.
BARRELS
AIR/WATER COOLED
The Prince® XL air cooled systems come standard with a straight air/water
cooled barrel assembly. An optional curved air/water cooled barrel assembly
(LE P/N KP2298-2, MK P/N 003-2152) is also available. In cases where
these barrels need to be extended or the tip threads have been damaged,
a Tip Extender (LE P/N KP2244-1, MK P/N 621-0424) can be adapted. The
same tips and threads can be used, however a longer Teflon liner (LE P/N
KP2226-1; MK P/N 931-0137) is required.
BARREL REMOVAL AND INSTALLATION
To remove a barrel assembly, loosen the patented EZ Lock™ Taper lock nut
assy MK P/N 003-2572 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 flush with the aluminum body block. Tighten
taper lock nut assembly firmly so that barrel cannot rotate.
BARREL ROTATION
To rotate a barrel assembly, loosen the patented EZ Lock™ Taper lock nut
assembly no more than 1 turn. Rotate barrel to the position of your choice
and retighten taper lock nut assembly firmly so that the barrel cannot rotate.
WARNING:
Do not attempt to weld without the barrel being tightly secured in the torch body, or
damage to the barrel or body may result.
CONTROLS AND SETTINGS
POTENTIOMETER
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 mini-
mum and maximum pot settings.
TRIGGER, GAS VALVE AND MICRO SWITCH
The torch trigger is designed so that when it is partially depressed, gas flow
starts via the valve located in the torch body, prior to ignition of the arc. When
the trigger is partially released after welding (extinguishing the arc), gas flow
continues until the trigger is fully released; built-in pre and post gas flow.
The micro switch is wired “Normally Open” and secured to the torch block
with two (2) screws. An insulator between the torch block and micro switch
prevents accidental shorting of the switch leads. The trigger pin reaches
through the handle and activates the micro switch just before the trigger bot-
toms out on the handle.

DRIVE AND IDLER ROLLS
GENERAL
The Prince® XL torch comes standard with knurled drive rolls which will
handle wire diameters from .023 - 1/16 inch. Optional grooved drive rolls are
also available for feeding aluminum wire if desired (see Optional kits).
Drive roll tension is accomplished by means of a pressure adjusting allen
screw located on the left hand side of the torch. Proper tension is achieved
when wire does not slip if a small amount of pressure is added to the wire as
it exits the tip.
----------- IMPORTANT -----------
NOTE: Over-tightening of the drive rolls will cause excessive knurling and/or
deformation of the wire. When the complete system is setup properly, feeding wire
out of the end of the torch and letting fall on the ground should form a large uniform
circle. If it forms a spiral or spring then there is too much tension in the system,
please refer to the Cabinet Owners Manual for adjustment to the tension setting.
INCORRECT DRIVE ROLL TENSION IS THE NUMBER ONE
CAUSE OF POOR WIRE FEED PERFORMANCE
---------------------------------------------
DRIVE ROLL INSTALLATION AND REMOVAL
Note:
Neither of the handles needs to be removed to access the Drive or Idler Rolls.
1. Using a 5/32” hex wrench, loosen the Idler Roll tension screw. This will
relieve the pressure against the drive roll.
2. Align the Drive Roll Removal Tool (P/N 931-0100) over the flats of the drive
roll. Hold the torch with one hand or on a table top, with the other hand give
the Removal Tool a quick snap-turn in the CLOCKWISE DIRECTION.
3. Once the drive roll is loose, continue to spin drive roll in the clockwise
direction to remove the drive roll from the torch.
4. Install a new drive roll on the left-hand threaded shaft. The drive roll will
self-tighten when it is feeding wire.
IDLER ROLL INSTALLATION AND REMOVAL
1. Using a slot type screwdriver, loosen idler screw, taking care not to lose
lock washer under idler roll.
2. Insert new idler roll and lock washer onto screw, insuring that idler groove
is toward top and lock washer is beneath.
Prince XL® - Owner's Manual - Page 7

3. Tighten.
4. Using a 5/32” hex wrench, turn the Idler Roll tension screw into the gear-
box housing and reference the Gearbox Assembly drawing to adjust the
pressure against the drive roll.
NOTE:
Lock washer must be under idler roll or it will not turn freely.

SECTION D
MAINTENANCE
PERIODIC MAINTENANCE
Maintenance of the torch will normally consist of a general cleaning of the
wire guide system, including tubes, drive rolls, and conduits at regular inter-
vals.
Remove spatter build-up from inside of nozzles with a hardwood stick.
The only parts on the Prince® XL that are subject to normal wear are the
conduit, contact tips, gas cups, barrel liners, drive and idler rolls. A supply of
these parts should be maintained on hand.
If repairs do become necessary, qualified shop maintenance personnel can
easily replace any part.
Your Cobramatic System is designed to provide years of reliable service.
Normal wear and component failure may require occasional service.
The number of units in operation and the importance of minimal “down time”
will determine to what extent spare parts should be stocked on hand. See the
“Recommended spare parts list” for the most commonly replaced parts.

SECTION E
TROUBLESHOOTING
Regardless of which torch or feeder used, all MK Products push-pull guns
operate on the same principle. The 115 VAC or 42VAC slave motor in the
feeder runs at a fast, constant speed, but has very low torque. It is always
trying to feed more wire than the torch motor wants, and when the motor gets
all it wants, it slows the slave motor, preventing a bird’s nest. Because of the
low torque produced by the slave motor, a brake system is used to prevent
wire overrun rather than tension.
The 24 VDC torch motor is controlled by a solid state speed control and a
pot located in the torch. The torch motor, potentiometer, and micro switch
are connected to the cabinet/control box via a control cable and amphenol. If
this cable becomes damaged, a variety of symptoms can occur, depending
on which wire(s) break. To test, check each wire for continuity and shorts.
With the increased torque rating in the current Prince XL motor, P/N 211-
0071, it now draws about twice as much current on start-up as the original
Prince motors P/N’s 211-0054 & 211-0056. Even though the duration of
start-up is very short, about 15msec, it is too much for the standard 2A fuse
to handle. For this reason, all 2A fuses in the motor circuitry (F1) should be
changed to a 3AG 4A fast blow 250V fuse, P/N 151-0043. This new 4A fuse
is sufficient for use on all model welding guns on the wire feeders, while still
providing protection for the circuitry from any shorts in the motor or motor
leads.
This fuse change includes all Cobramatic, Cobramatic II and CobraMig 250/
260, WC-1, Torpedo’s, and any other motor circuits powering Prince XL or
Spool Guns using motor P/N 211-0071.
Remember the micro switch in the torch activates both the 115 VAC or 42
VAC and 24 VDC circuits in the cabinet. Therefore, if the slave motor and
brake solonoid operate, but the torch does not, look more toward the 24 VDC
circuits, speed control, control cable, or the torch motor. If nothing operates,
look more toward the 115 VAC or 42 VAC input, micro switch leads, or micro
switch.
The complete pot assembly is connected to the motor and set into the
handles. If the pot is disassembled, the pot knob can be put on the shaft in
any position and secured with the set screw. Turn the knob fully CCW, then
fully CW, then fully CCW again. This will self-align the pot, i.e., fully CCW will
be minimum wire feed speed, and fully CW will be maximum wire speed.

Troubleshooting Guide
Trouble
Cause
Remedy
115/42VAC control fuse in feeder.
Replace fuse.
No wire feed at torch, feeder no
operating, i.e. no slave motor or brake
solenoid.
Micro-switch defective/not being
activated.
Replace switch. Check switch for
operation.
Broken electrical cable.
Check micro-switch wires for continuity.
4 amp fuse (F1) in feeder/Control box
blown.
Check motor leads for shorts; then
replace fuse.
Bad potentiometer.
Check potentiometer with meter.
No wire feed at torch, feeder operating
properly.
Check motor and potentiometer wire
for continuity.
Broken electrical cable.
See specific cabinet/control box owners
manual for speed control operation.
Bad speed control/PCB
Loose or no cable connections.
Check all power connections.
Check power supply owner’s manual
for location and type of contactor signal
required, i.e., closing or 115 VAC.
Wire feeds, but welding wire is not
energized.
Contactor control cable loose or in
wrong position.
Welding power source.
Dirty or worn conduit.
Check power source material.
Blow out or replace conduit.
Adjust pressure at both feeder and
torch.
Incorrect ressure on drive rolls.
Idler roll stuck.
Wire feeds erratically.
Check for lock washer under idler roll,
or replace if damaged.
Wrong size contact tip.
Bad potentiometer.
See contact tip table.
Check with meter.
Check potentiometer wires for
continuity or short.
Broken electrical cable.
Bad speed control.
Wire feeds one speed only.
See specific cabinet/control owner’s
manul for speed control operation.
Idler roll upside-down.
Place groove in idler roll toward top.
Replace wire guide.
Wire walks out of drive rolls.
Poor gas/water flow.
Rear wire guide missing.
Slide barrel insulator downa nd thread
until it bottoms out, covering coolant
ports and exposing gas ports.
Incorrect placement of barrel insulator.

TESTING THE TORCH
MOTOR CHECK
Remove the torch connector from the cabinet.
Using the torch Amphenol, check the resistance across pins “A” and “B”
(motor leads). The resistance across the motor should be between 5-10
ohms.
If an open circuit or short exist, check the motor leads and motor indepen-
dently.
TESTING THE POTENTIOMETER
Using the torch Amphenol, check the resistance across pin “D” (wiper) and
pin “C”. The resistance should vary from 0 - 5K ohms.
Check the resistance across pin “D” (wiper) and pin “G”. The resistance
should vary from 5K - 0 ohms.
TESTING THE MICRO SWITCH
Using the torch Amphenol, check for continuity across pins “E” and “F” when
the trigger is pressed.
