CAUTION : READ BEFORE A TTEMPTING INSTALLATION, OPERATION OR
MAINTENANCE OF THIS EQUIPMENT
1-1 INTRODUCTION
This equipment is intended for ultimate
application by commercial/industrial
users and for operation by persons trained
and experienced in the use and
maintenance of welding equipment.
Operation should not be undertaken
without adequate training in the use of
such equipment. Training is available
from many public and private schools or
similar facilities.
Safe practices in the installation,
operation and maintenance of this
equipment requires proper training in the
art, a careful study of the information
provided with the equipment, and the use
of common sense. Rules for safe use
are generally provided by suppliers of
welding power sources, compressed gas
suppliers, and electrode suppliers.
Careful compliance with these rules will
promote safe use of this equipment.
The following Safety Rules cover some
of the more generally found situations.
READ THEM CAREFULLY. In case of
any doubt, obtain qualified help before
proceeding.
1-2 GENERAL PRECAUTIONS
A. Burn Prevention
ELECTRIC ARC WELDING
PRODUCES HIGH INTENSITY HEAT
AND ULTRAVIOLET RADIANT
ENERGY WHICH MAY CAUSE
SERIOUS AND PERMANENT EYE
DAMAGE AND WHICH MAY DAMAGE
ANY EXPOSED SKIN AREAS.
Wear helmet with safety goggles or
glasses with side shields underneath,
appropriate filter lenses or plates
(protected by clear cover glass). This is
a must for welding or cutting (and
chipping) to protect the eyes from radiant
energy and flying metal. Replace cover
glass when broken, pitted, or spattered.
Medical first aid and eye treatment. First
aid facilities and a qualified first aid
person should be available for each shift
unless medical facilities are close by for
immediate treatment of flash burns of the
eyes and skin burns.
Wear protective clothing - leather (or
asbestos) gauntlet gloves, hat, and high
safety-toe shoes. Button shirt collar and
pocket flaps, and wear cuffless trousers
to avoid entry of sparks and slag.
Avoid oily or greasy clothing. A spark
may ignite them.
Flammable hair preparations should not
be used by persons intending to weld or
cut.
Hot metal such as electrode stubs and work
pieces should never be handled without
gloves.
Ear plugs should be worn when working on
overhead or in a confined space. A hard
hat should be worn when others work
overhead.
B. Toxic Fume Prevention
WARNING: The use of this product may
result in exposure to chemicals known to
the State of California to cause cancer and
birth defects or other reproductive harm.
Adequate ventilation. Severe discomfort,
illness or death can result from fumes,
vapors, heat, or oxygen enrichment or
depletion that welding (or cutting) may
produce. Prevent them with adequate
ventilation. NEVER ventilate with oxygen.
Lead-, cadmium-, zinc-, mercury-,
beryllium-bearing and similar materials,
when welded or cut, may produce harmful
concentrations of toxic fumes. Adequate
local exhaust ventilation must be used, or
each person in the area, as well as the
operator, must wear an air-supplied
respirator. For beryllium, both must be
used.
Metals coated with or containing materials
that emit toxic fumes should not be heated
unless coating is removed form the work
surface, the area is well ventilated, or the
operator wears an air-supplied respirator.
Work in a confined space only while it is
being ventilated and, if necessary, while
wearing an air-supplied respirator.
Gas leaks in a confined space should be
avoided. Leaked gas in large quantities can
change oxygen concentration dangerously .
Do not bring gas cylinders into a confined
space.
Leaving confined space, shut OFF gas
supply at source to prevent possible
accumulation of gases in the space if
downstream valves have been accidentally
opened or left open. Check to be sure that
the space is safe before reentering it.
Vapors from chlorinated solvents can be
decomposed by the heat of the arc (or
flame) to form PHOSGENE, a highly toxic
gas, and other lung and eye irritating
products. The ultraviolet (radiant) energy
of the arc can also decompose
trichloroethylene and perchloroethylene
vapors to form phosgene. DO NOT WELD
or cut where solvent vapors can be drawn
into the welding or cutting atmosphere or
where the radiant energy can penetrate to
atmospheres containing even minute
amounts of trichloroethylene or
perchloroethylene.
C. Fire and Explosion Prevention
Causes of fire and explosion are:
combustibles reached by the arc, flame,
flying sparks, hot slag, or heated
material, misuse of compressed gases
and cylinders, and short circuits.
BE AWARE THAT flying sparks or falling
slag can pass through cracks, along
pipes, through windows or doors, and
through wall or floor openings, out of sight
of the goggled operator. Sparks can fly
many feet.
To prevent fires and explosion:
Keep equipment clean and operable, free
of oil, grease, and (in electrical parts) of
metallic particles that can cause short
circuits.
If combustibles are in area, do NOT weld
or cut. Move the work if practicable, to
an area free of combustibles. Avoid paint
spray rooms, dip tanks, storage areas,
ventilators. If the work cannot be moved,
move combustibles at least 35 feet away ,
out of reach of sparks and heat; or protect
against ignition with suitable and snugfitting, fire-resistant covers or shields.
Walls touching combustibles on opposite
sides should not be welded on (or cut).
Walls, ceilings, and floor near work
should be protected by heat-resistant
covers or shields.
Fire watcher must be standing by with
suitable fire extinguishing equipment
during and for some time after welding
or cutting if:
1. Appreciable combustibles (including
building construction) are within 35 feet.
2. Appreciable combustibles are further
than 35 feet, but can be ignited by sparks.
3. Openings (concealed or visible) in
floors or walls within 35 feet may expose
combustibles to sparks.
4. Combustibles adjacent to walls,
ceilings, roofs, or metal partitions can be
ignited by radiant or conducted heat.
Hot work permit should be obtained
before operation to ensure supervisor’s
approval that adequate precautions have
been taken.
After work is done, check that area is free
of sparks, glowing embers, and flames.
An empty container that held
combustibles, or that can produce
flammable or toxic vapors when heated,
must never be welded on or cut, unless
container has first been cleaned in
accordance with industry standards.
This includes: a thorough steam or
caustic cleaning (or a solvent of water
washing, depending on the combustible’s
solubility), followed by purging and
inerting with nitrogen or carbon dioxide,
and using protective equipment.
Water-filling just below working level may
substitute for inerting.
A container with unknown contents
should be cleaned (see paragraph
above). Do NOT depend on sense of
smell or sight to determine if it is safe to
weld or cut.
Hollow castings or containers must be
vented before welding or cutting. They
can explode.
Explosive atmospheres. NEVER weld
or cut where the air may contain
flammable dust, gas, or liquid vapors
(such as gasoline).
D. Compressed Gas Equipment
The safe handling of compressed gas
equipment is detailed in numerous
industry publications. The following
general rules cover many of the most
common situations.
1. Pressure Regulators
Regulator relief valve is designed to
protect only the regulator from
overpressure; it is not intended to protect
any downstream equipment. Provide
such protection with one or more relief
devices.
Never connect a regulator to a cylinder
containing gas other than that for which
the regulator was designed.
Remove faulty regulator from service
immediately for repair (first close cylinder
valve). The following symptoms indicate
a faulty regulator:
Leaks - if gas leaks externally.
Excessive Creep - if delivery pressure
continues to rise with downstream valve
closed.
Faulty Gauge - if gauge pointer does not
move off stop pin when pressurized, nor
returns to stop pin after pressure release.
Repair. Do NOT attempt repair. Send
faulty regulators for repair to
manufacturer’s designated repair center,
where special techniques and tools are
used by trained personnel.
2. Cylinders
Cylinders must be handled carefully to
prevent leaks and damage to their walls,
valves, or safety devices:
Avoid electrical circuit contact with
cylinders including third rails, electrical
wires, or welding circuits. They can
produced short circuit arcs that may lead
to a serious accident. (See 1-3C)
ICC or DOT marking must be on each
cylinder. It is an assurance of safety
when the cylinder is properly handled.
Identifying gas content. Use only
cylinders with name of gas marked on
them; do not rely on color to identify gas
content. Notify supplier if unmarked.
NEVER DEFACE or alter name, number ,
or other markings on a cylinder. It is
illegal and hazardous.
Empties: Keep valves closed, replace caps
securely; mark MT; keep them separate
from FULLS, and return promptly.
Prohibited use. Never use a cylinder or its
contents for other than its intended use,
NEVER as a support or roller.
Locate or secure cylinders so they cannot
be knocked over.
Passageways and work areas. Keep
cylinders clear of areas where they may be
stuck.
Transporting cylinders. With a crane, use
a secure support such as a platform or
cradle. Do NOT lift cylinders off the ground
by their valves or caps, or by chains, slings,
or magnets.
Do NOT expose cylinders to excessive heat,
sparks, slag, and flame, etc. that may cause
rupture. Do not allow contents to exceed
55 degrees C (130 degrees F.) Cool with
water spray where such exposure exists.
Protect cylinders, particularly valves from
bumps, falls, falling objects, and weather.
Replace caps securely when moving
cylinders.
Stuck valve. Do NOT use a hammer or
wrench to open a cylinder valve that cannot
be opened by hand. Notify your supplier.
Mixing gases. NEVER try to mix any gases
in a cylinder.
NEVER refill any cylinder.
Cylinder fittings should never be modified
or exchanged.
3. Hose
Prohibited use. Never use hose other than
that designed for the specified gas. A
general hose identification rule is: red for
fuel gas, green for oxygen, and black for
inert gases.
Use ferrules or clamps designed for the
hose (not ordinary wire or other substitute)
as a binding to connect hoses to fittings.
No copper tubing splices. Use only
standard brass fittings to splice hose.
Avoid long runs to prevent kinks and abuse.
Suspend hose off ground to keep it from
being run over, stepped on, or otherwise
damaged.
Coil excess hose to prevent kinks and
tangles.
Protect hose from damage by sharp edges,
and by sparks, slag, and open flame.
Examine hose regularly for leaks, wear , and
loose connections. Immerse pressured
hose in water; bubbles indicate leaks
Repair leaky or worn hose by cutting area
out and splicing. Do NOT use tape.
4. Proper Connections
Clean cylinder valve outlet of impurities that
may clog orifices and damage seats before
connecting regulator. Except for hydrogen,
crack valve momentarily, pointing outlet
away from people and sources of ignition.
Wipe with a clean, lintless cloth.
Match regulator to cylinder. Before
connecting, check that the regulator label
and cylinder marking agree, and that the
regulator inlet and cylinder outlet match.
NEVER Connect a regulator designed for
a particular gas or gases to a cylinder
containing any other gas.
Tighten connections. When assembling
threaded connections, clean and smooth
seats where necessary. Tighten. If
connection leaks, disassemble, clean,
and retighten, using properly fitting
wrench.
Adapters. Use a CGA adapter (available
from your supplier) between cylinder and
regulator, if one is required. Use two
wrenches to tighten adapter marked
RIGHT and LEFT HAND threads.
Regulator outlet (or hose) connections
may be identified by right hand threads
for oxygen and left hand threads (with
grooved hex on nut or shank) for fuel gas.
5. Pressurizing Steps:
Drain regulator of residual gas through
suitable vent before opening cylinder (or
manifold valve) by turning adjusting
screw in (clockwise). Draining prevents
excessive compression heat at high
pressure seat by allowing seat to open
on pressurization. Leave adjusting screw
engaged slightly on single-stage
regulators.
Stand to side of regulator while opening
cylinder valve.
Open cylinder valve slowly so that
regulator pressure increases slowly.
When gauge is pressurized (gauge
reaches regulator maximum) leave
cylinder valve in following position: for
oxygen and inert gases, open fully to seal
stem against possible leak; for fuel gas,
open to less than one turn to permit quick
emergency shut-off.
Use pressure charts (available from your
supplier) for safe and efficient
recommended pressure settings on
regulators.
Check for leaks on first pressurization
and regularly thereafter. Brush with soap
solution. Bubbles indicate leaks. Clean
off soapy water after test; dried soap is
combustible.
E. User Responsibilities
Follow all Safety Rules.
Remove leaky or defective equipment
from service immediately for repair.
Read and follow user manual
instructions.
F . Leaving Equipment Unattended
Close gas supply at source and drain
gas.
G. Rope Staging-Support
Rope staging-support should not be used
for welding or cutting operation; rope may
burn.
1-3 ARC WELDING
Comply with precautions in 1-1, 1-2, and
this section. Arc Welding, properly done,
is a safe process, but a careless operator
invites trouble. The equipment carries
high currents at significant voltages. The
arc is very bright and hot. Sparks fly,
fumes rise, ultraviolet and infrared energy
radiates, weldments are hot, and
compressed gases may be used. The
wise operator avoids unnecessary risks
and protects himself and others from
accidents.
A. Burn Protection
Comply with precautions in 1-2.
The welding arc is intense and visibly
bright. Its radiation can damage eyes,
penetrate lightweight clothing, reflect
from light-colored surfaces, and burn the
skin and eyes. Skin burns resemble
acute sunburn; those from gas-shielded
arcs are more severe and painful. DON’T
GET BURNED; COMPLY WITH
PRECAUTIONS.
1. Protective Clothing
Wear long-sleeve clothing in addition to
gloves, hat, and shoes. As necessary,
use additional protective clothing such
as leather jacket or sleeves, flameproof
apron, and fire-resistant leggings. Avoid
outer garments of untreated cotton.
Bare skin protection. Wear dark,
substantial clothing. Button collar to
protect chest and neck, and button
pockets to prevent entry of sparks.
2. Eye and Head Protection
Protect eyes from exposure to arc. Eyes
may be damaged by radiant energy when
exposed to the electric arc, even when
not looking in the direction of the arc.
Never look at an electric arc without
protection.
Welding helmet or shield containing a
filter plate shade no. 12 or denser must
be used when welding. Place over face
before striking arc.
Protect filter plate with a clear cover plate.
Cracked or broken helmet or shield
should NOT be worn; radiation can be
passed through to cause burns.
Cracked, broken, or loose filter plates
must be replaced IMMEDIATELY.
Replace clear cover plate when broken,
pitted, or spattered.
Flash goggles with side shields MUST
be worn under the helmet to give some
protection to the eyes should the helmet
not be lowered over the face before an
arc is struck. Looking at an arc
momentarily with unprotected eyes
(particularly a high intensity gas-shielded
arc) can cause a retinal burn that may
leave a permanent dark area in the field
of vision.
3. Protection of Nearby Personnel
Enclose the welding area. For production
welding, a separate room or enclosed
bay is best. In open areas, surround the
operation with low-reflective,
noncombustible screens or panels. Allow
for free air circulation, particularly at floor
level.
Viewing the weld. Provide face shields
for all persons who will be looking directly
at the weld.
Others working in area. See that all persons
are wearing flash goggles.
Before starting to weld, make sure that
screen flaps or bay doors are closed.
B. Toxic Fume Prevention
Comply with precautions in 1-2B.
Generator engine exhaust must be vented
to the outside air. Carbon monoxide can
kill.
C. Fire and Explosion Prevention
Comply with precautions in 1-2C.
Equipment’s rated capacity. Do not
overload arc welding equipment. It may
overheat cables and cause a fire.
Loose cable connections may overheat or
flash and cause afire.
Never strike an arc on a cylinder or other
pressure vessel. It creates a brittle area
that can cause a violent rupture or lead to
such a rupture later under rough handling.
D. Compressed Gas Equipment
Comply with precautions in 1-2D.
E. Shock Prevention
Exposed electrically hot conductors or other
bare metal in the welding circuit, or in
ungrounded, electrically-HOT
equipment can fatally shock a person
whose body becomes a conductor. DO
NOT STAND, SIT, LIE, LEAN ON, OR
TOUCH a wet surface when welding without
suitable protection.
To protect against shock:
Keep body and clothing dry . Never work in
damp area without adequate insulation
against electrical shock. Stay on a dry
duckboard, or rubber mat when dampness
or sweat cannot be avoided. Sweat, sea
water, or moisture between body and an
electrically HOT part - or grounded metal reduces the body surface electrical
resistance, enabling dangerous and
possibly lethal currents to flow through the
body.
1. Grounding the Equipment
When installing, connect the frames of each
unit such as welding power source, control,
work table, and water circulator to the
building ground. Conductors must be
adequate to carry ground currents safely.
Equipment made electrically HOT by stray
currents may shock, possibly fatally. Do
NOT GROUND to electrical conduit, or to a
pipe carrying ANY gas or a flammable liquid
such as oil or fuel.
Three-phase connection. Check phase
requirement of equipment before installing.
If only three-phase power is available,
connect single-phase equipment to only two
wires of the three-phase line. Do NOT
connect the equipment ground lead to the
third (live) wire, or the equipment will
become electrically HOT - a dangerous
condition that can shock, possibly fatally.
Before welding, check ground for continuity .
Be sure conductors are touching bare metal
of equipment frames at connections.
If a line cord with a ground lead is provided
with the equipment for connection to a
switch box, connect the ground lead to
the grounded switch box. If a three-prong
plug is added for connection to a
grounded mating receptacle, the ground
lead must be connected to the ground
prong only . If the line cord comes with a
three-prong plug, connect to a grounded
mating receptacle. Never remove the
ground prong from a plug, or use a plug
with a broken ground prong.
2. Connectors
Fully insulated lock-type connectors
should be used to join welding cable
lengths.
3. Cables
Frequently inspect cables for wear,
cracks, and damage. IMMEDIATELY
REPLACE those with excessively worn
or damaged insulation to avoid possibly
lethal shock from bared cable. Cables
with damaged areas may be taped to give
resistance equivalent to original cable.
Keep cable dry, free of oil and grease,
and protected from hot metal and sparks.
4. T erminals and Other Exposed Parts
Terminals and other exposed parts of
electrical units should have insulating
covers secured before operation.
5. Electrode Wire
Electrode wire becomes electrically HOT
when the power switch of gas metal-arc
welding equipment is ON and welding
gun trigger is pressed. Keep hands and
body clear of wire and other HOT parts.
6. Safety Devices
Safety devices such as interlocks and
circuit breakers should not be
disconnected or shunted out.
Before installation, inspection, or service
of equipment, shut OFF all power, and
remove line fuses (or lock or red-tag
switches) to prevent accidental turning
ON of power. Disconnect all cables from
welding power source, and pull all 115
volts line-cord plugs.
Do not open power circuit or change
polarity while welding. If, in an
emergency, it must be disconnected,
guard against shock burns or flash from
switch arcing.
Leaving equipment unattended. Always
shut OFF, and disconnect all power to
equipment.
Power disconnect switch must be
available near the welding power source.

Introduction
This manual details the installation and operation of your PrinceTMXL Torch,
and PrinceTMXL Spool Gun.
These torches have 7 pin “W” clocked amphenol connectors and are designed 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 0050162, 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 W eld 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 assembly (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.

All tips stamped with tip I.D.
NOTE: As a rule of thumb, use the smaller I.D. tip for steel, stainless steel and the 5000 series
aluminum. Softer alloys such as the 1000 and 4000 series aluminum require more clearance
and, therefore, use a larger I.D. tip.
