READ THE FOLLOWING CAREFULLY
The parts diagram(s) in this manual are provided for
reference only. Neither the manufacturer nor distributor
makes any representation or warranty of any kind to
the buyer that he or she is qualied to make any repairs
to the product. Most manufacturers and distributors
expressly state that all repairs and part replacements
should be undertaken by certified and licensed
technicians and not by the buyer. The buyer assumes all
risk and liability arising out of his or her repairs to the
original product or replacement parts hereto; or, arising
out of his or her installation of replacement parts hereto.
FOREWORD
The equipment you have purchased was thoroughly
tested and inspected when it left the factory. With
reasonable care, and by following the instructions, it will
give you many years of efcient, trouble-free service.
The instructions, applications and techniques described
in this manual are designed to aid you in the basic
principles of using the Stable Cut.
IMPORTANT
• Always wear safety goggles with tinted lenses.
• Before starting work, always check for leaks by
brushing a thick soap solution on all connections.
Open valve and watch for bubbles to appear at

points of leakage.
• Tighten loose connections with a wrench.
• Never use a ame to check for gas leaks.
• Do not use a hose that is worn, or any equipment
that is in need of repair.
• Never use oxygen to blow debris off work area or
clothing.
• Purge fuel gas and oxygen passages separately
before lighting up the torch.
• Secure cylinders to a cart, wall or post to prevent
them from falling.
• Always use reverse-ow check valves on torches
and regulators. This reduces the possibility of mixing
gases inside the regulators or hoses.
• Do not use oil or grease on the equipment. Oil and
grease are easily ignited and burn violently in the
presence of oxygen, which is under pressure.
• Empty cylinders should be kept in specied areas
and clearly marked “Empty.”
• Before lighting the torch, follow all personal and
equipment safety regulations.
• Always recommends using flash back arrestors.

SAFETY SIGNS FOUND IN THIS MANUAL
Danger sign indicates a hazard that will cause
death or serious injury if the dangerous situation
is ignored.
Warning sign indicates a hazard that could cause
death or serious injury if the warning is ignored.

EZ-CUT Manual
Caution sign indicates a hazard that may
cause minor or moderate injury if the caution
is ignored. It also may indicate a hazard
which will cause property damage, even if
no one is injured.
Notice sign indicates any information pertaining
to the product or its proper usage.
GENERAL SAFETY
Always keep an approved fire
extinguisher accessible while performing
oxy-fuel operations.
Never touch work pieces until they are
completely cooled.
Keep work area well ventilated.
Flying sparks and hot metal can cause injury.
Take necessary precautions to reduce the
possibility of injury, such as protective clothing
and shielding.
PROTECTIVE CLOTHING & SHIELDING
All persons operating this equipment or in the area,
while this equipment is in use, must wear protective
welding gear including:
• welding goggles/face shield/safety glasses (with
side shield protection)
• ame resistant clothing
Stable Cut Manual
Stable Cut Manual

EZ-CUT Manual
• leather welding gloves
• full foot protection
Oxy-fuel operations produce intense light,
heat and ultraviolet (UV) rays. The intense
light and UV rays can cause injury to eyes
and skin. Eye protection must have a minimum
shade of 5. Take all precautions to reduce the
possibility of injury to eyes and skin.
Oxy-fuel operations cause sparks and heat metal
to temperatures that can cause severe burns. Take
necessary precautions to reduce the possibility of
obtaining skin and clothing burns.
Keep all clothing and protective equipment
free of oil and grease. These substances can
ignite and will burn violently in the presence
of pure oxygen.
Wear ear plugs when welding or cutting
overhead to prevent spatter or slag from falling
into the ears.
Use ame resistant barriers as needed
to protect others in the area from heat,
sparks, intense light and ultraviolet rays.
OPERATIONAL HAZARDS
There must be two (2) O-rings on the coupler
cone end of the cutting attachment or welding
nozzle mixer. The absence of either O-ring from
Stable Cut Manual

EZ-CUT Manual
the cone end can lead to ashback within the
torch handle, cutting attachment or welding
nozzle mixer.
Inspect the tapered seating surfaces on the
cutting tip and in the cutting attachment head.
Have a qualied technician resurface the seat
area if it has dents or is burned. A poor seating
surface may result in backre or ashback.
The following instructions apply to acetylene gas
only. Contact your gas supplier for information
about other fuel gases.
When the ame goes out with a loud pop, it’s called
a backre. Backre can be caused by (1) operating
the torch at lower pressures than required for the
tip used, (2) touching the tip against the work, (3)
overheating the tip or (4) the tip is obstructed. If
backre occurs, shut off the torch handle valves
(oxygen rst) and x the problem before relighting
the torch.
Flashback is a condition that results when the ame
ashes back into the torch and burns inside with
a shrill hissing or squealing noise. If flashback
occurs, close the torch handle valves (oxygen
rst) immediately. Flashback generally indicates
a problem that should be fixed. A clogged tip,
valves functioning improperly or incorrect oxygen/
acetylene pressure could lead to flashback. Be
certain to nd the cause before relighting the torch.

ASSEMBLY INSTRUCTIONS
1. To begin, slide the Horizontal Arm (e) into the opening
adjacent to the Speed Control Mechanism (c). The
Horizontal Arm (e) can be inserted from either end,
depending on which side of the Track (b) the Tip Holder
(j) is desired. Install an Adjustment Knob (f) and tighten
to hold the Horizontal Arm (e) in place.
2. Next, insert the Vertical Arm (g) into the opening in
the Horizontal Arm (e) from the bottom. Install an
Adjustment Knob (h) and tighten to hold the Vertical
Arm (g) in place.
3. Finally, attach the Tip Holder (j) to the receptacle on
the bottom of the Vertical Arm (g), and secure on the
opposite side with the provided D-Shape Washer and
Adjustment Knob (i).

OPERATION INSTRUCTIONS
1. Secure Stable Cut to work surface by placing the
magnets on the material to be cut, being careful
to avoid catching ngers and clothing. Make sure
to align the track parallel to the desired cutting
direction, with the tip holder positioned above the
cut line.
2. Before lighting the torch, place the cutting tip into the
tip holder. Disengage the speed control by ipping
the lever on the top of the mechanism into the “up”
position. Move the torch and carriage along the
track to ensure the desired placement has been
achieved. Slight adjustments of the track placement
can be made by gently bumping the sides of the
track with an open palm. Hammers and/or mallets
should never be used to adjust positioning, as this
may damage the track.
3. Loosen the knobs to adjust the tip height, cut angle
(bevel), and the distance of the torch relative to the
track if needed. Retighten knobs when nished.
4. Once the placement has been nalized, move the
carriage to the “start” position of the cut and engage
the speed control (if desired) by ipping the lever on
top of the carriage into the “down” position.
5. Remove the torch from the mechanism, and light as
usual. Once the torch is lit, carefully and securely
place the tip back into the tip holder. Use caution to
avoid unnecessarily exposing the Stable Cut to direct
ames from the torch.
6. When the material is ready to be cut, engage
the cutting oxygen as usual and either push
Stable Cut Manual

EZ-CUT Manual
or pull (depending on desired setup) the torch
along the track.
7. When the cut is complete, extinguish the torch and
remove it.
Parts of the Stable Cut may be hot after use.
Always wear protective clothing, gloves, and
safety glasses.
The Stable Cut is designed to give resistance
when pushing or pulling the mechanism along
the track. It is this pre-set resistance that allows
for consistent, smooth, and clean cuts. Because
the mechanism is pre-calibrated for a set speed
range, excessive use of force by the operator
when pushing or pulling the mechanism can
cause the carriage to skip, leading to a possible
reduction of cut quality. Avoid the excessive use
of force for maintained consistency.
