Transportation) and CGA (Compressed Gas Association) regulations. Contact your gas supplier for more information on
the proper use of compressed gases.
OM-280758 Page 1
. In this document, the phrase “welding and cutting” also refers to other oxy-fuel operations like brazing and heating.
READ INSTRUCTIONS.
D Read and follow all labels and the Owner’s Manual carefully be-
fore installing, operating, or servicing equipment. Read the safety
information at the beginning of the manual and in each section.
D Use only genuine replacement parts from the manufacturer.
D Perform installation, maintenance, and service according to the
Owner’s Manuals, industry standards, and national, state, and
local codes.
HOT PARTS can burn.
D Do not touch hot parts bare handed.
D Allow cooling period before working on equipment.
D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.
FUMES AND GASES can be hazardous.
Welding and cutting produces fumes and gases. Breathing these
fumes and gases can be hazardous to your health.
D Keep your head out of the fumes. Do not breathe the fumes.
D Ventilate the work area and/or use local forced ventilation at the
flame to remove welding and cutting fumes and gases. Some gases
(natural gas and acetylene) are lighter than air and will collect in high
areas. Other gases (propane and butane) are heavier than air and
will collect in low areas. Heavier-than-air gases are more difficult to
diffuse and are more likely to accumulate. The recommended way
to determine adequate ventilation is to sample for the composition
and quantity of fumes and gases to which personnel are exposed.
D If ventilation is poor, wear an approved air-supplied respirator.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coatings, cleaners, degreasers, fluxes, and metals.
D Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding and cutting fumes and gases can displace air and lower the oxygen level, causing injury or death. Be
sure the breathing air is safe. Test atmospheres in confined areas
for explosive and toxic gases before using oxy-fuel equipment.
D Do not weld or cut in locations near degreasing, cleaning, or
spraying operations. The heat from welding or cutting flame can
react with vapors to form highly toxic and irritating gases.
D Do not weld or cut on coated metals, such as galvanized, lead, or
cadmium-plated steel unless the coating is removed from the affected area, the area is well ventilated, and while wearing an airsupplied respirator. The coatings and any metals containing
these elements can give off toxic fumes if welded or cut.
D Do not weld or cut on sealed air conditioning or refrigeration systems unless all refrigerants have been removed from the system.
OM-280758 Page 2
BUILDUP OF GAS can injure or kill.
D Shut off compressed gas supply when not in use.
D Always ventilate confined spaces or use approved air-supplied
respirator.
LIGHT RAYS can burn eyes and skin.
Light rays from the welding and cutting process produce intense visible
and invisible (ultraviolet and infrared) rays that can burn eyes and skin.
Sparks fly off from the weld.
D Wear approved face protection fitted with a proper shade of filter
lenses to protect your face and eyes from light rays and sparks
when welding, cutting, or watching (see ANSI Z49.1 and Z87.1
listed in Safety Standards).
D Wear welding goggles, or wear welding helmet/welding faceshield over approved goggles/safety glasses with side shields.
D Use protective screens or barriers to protect others from flash,
glare and sparks; warn others not to watch the welding or cutting.
D Wear body protection made from leather or flame-resistant clothing (FRC). Body protection includes oil-free clothing such as
leather gloves, heavy shirt, cuffless trousers, high shoes, and a
cap.
WELDING AND CUTTING can cause
fire or explosion.
Welding and cutting on closed containers, such as tanks, drums, or
pipes, can cause them to blow up. Sparks can fly off from the welding or
cutting operations. The torch flame, flying sparks, hot workpiece, and
hot equipment can cause fires and burns. Check and be sure the area is
safe before doing any welding or cutting.
D Do not use this welding and cutting equipment with gases and
D
pressures other than those for which it is intended. Oxygen is not
flammable; however, the presence of pure oxygen will drastically
increase the speed and force with which burning takes place. Oxygen must never be allowed to contact grease, oil, or other petroleum-based substances; therefore, be sure there is no oil or grease
on the regulator, cylinder, valves, or equipment. Do not use petroleum-based pipe sealants. Do not use sealants on metal-to-metal
seals, such as hose and CGA cylinder connections; use
PTFE-based sealant (PTFE tape) on pipe threads. Do not use or
store near excessive heat (above 125° F/51.5° C) or open flame.
Do not refer to oxygen as air and do not use oxygen as a substitute
for compressed air. Do not use oxygen to clean clothes or work
area, for ventilation, or to operate pneumatic tools. Open oxygen
cylinder valves slowly. Be sure regulator adjusting handle is in the
full out (off) position before opening oxygen cylinder valve.
Inspect all equipment before use. Do not use damaged, defective,
or improperly adjusted welding and cutting equipment. Make sure
levers and valves work properly, threads on equipment are clean
(no grease or oil) and not deformed, gauges are intact and easy to
read, regulator is clean and free of oil or dirt, and fittings are properly sized for the cylinder. Make sure hoses are clean (no grease or
oil) and ferrules are properly installed so the fitting does not slip inside the hose. Be sure all connections are tight.

restor be installed between the torch handle and the regulator. Check
valves do not prevent the propagation of a flame upstream (flashback) but are designed to prevent the unintentional backflow of gases
into the cutting attachment, torch, hoses, or regulator which could
cause an explosion or fire. A flashback arrestor can be installed on the
torch handle or regulator outlet instead of a check valve. Miller flashback arrestors have a reverse flow check valve and prevent the propagation of a flame upstream. If a flashback arrestor is installed, a
check valve is not necessary. Using a flashback arrestor and a check
valve can reduce gas flow and affect torch operation. To help prevent
the reverse flow of gases, be sure the cylinders contain enough gas to
complete the work.
Understand the properties and applications of a gas, and how to
safely use a gas, before placing it in service.
Perform work only in an area with a fireproof floor (concrete). Do
not heat concrete because it can expand and explode violently.
Perform work on a fireproof surface. Use heat resistant shields to
protect nearby walls and flooring.
Do not use if grease or oil is present on equipment or if equipment is
damaged. Have equipment cleaned/repaired by a qualified person.
Do not open a cylinder valve quickly or the regulator can be damaged and cause a fire.
Do not open acetylene cylinder valve more than 1−1/2 turns. (For
all gases except acetylene, open cylinder valve fully to backseal
the cylinder valve.) Keep cylinder wrench on the cylinder for quick
shut-off.
Do not slightly open or “crack” fuel cylinder valve to blow debris
from the valve outlet. Remove the debris using nitrogen, air, or a
clean, oil-free rag.
Always purge gas from the system before lighting torch. Purge gas
in a well-ventilated area and away from flame or sparks.
Keep torch flame or sparks away from cylinder, regulator, and gas
hose.
Use only the gases recommended by the manufacturer of the
oxy-fuel equipment being used.
Never light a torch with matches or a lighter. Always use a striker.
Do not use acetylene above 15 psi (103 kPa) flowing. It is acceptable to use acetylene regulators that indicate a static pressure up
to 22 psi (151 kPa).
Do not withdraw acetylene from a cylinder at a rate exceeding 1/7
of the cylinder capacity per hour (50 SCFH for a 350 ft3 cylinder).
Maximum withdrawal rate for a half-full 100 lb propane cylinder at
70°F is 75 SCFH (2124 lph).
When required flows (SCFH) exceed the recommended withdrawal
rate from one cylinder, then additional cylinders must be manifolded to
provide safe and efficient operation.
When using liquid oxygen, tips may require greater gas volume than a
single cylinder is capable of producing. External evaporators or manifolding multiple cylinders may be necessary to supply sufficient gas
flows.
D Do not use long gas hoses or hoses with multiple connections be-
D
cause they restrict gas flow and reduce gas pressure. These conditions can cause backfires and flashbacks, and reduce equipment efficiency.
Do not use torch if you smell gas. Check oxy-fuel system for leaks
with an approved leak detection solution or leak detector. Never
test for gas leaks with a flame.

ting operation. If this is not possible, tightly cover them with approved covers.
Do not weld or cut where flying sparks can strike flammable
material.
Protect yourself and others from flying sparks and hot metal.
Be alert that welding and cutting sparks and hot materials from
welding and cutting can easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding or cutting on a ceiling, floor, bulkhead, or
partition can cause fire on the hidden side.
Do not cut or weld on tire rims or wheels. Tires can explode if heated. Repaired rims and wheels can fail. See OSHA 29 CFR
1910.177 listed in Safety Standards.
Do not weld or cut on containers that have held combustibles, or on
closed containers such as tanks, drums, or pipes unless they are
properly prepared according to AWS F4.1 (see Safety Standards).
Do not weld or cut where the atmosphere can contain flammable
dust, gas, or liquid vapors (such as gasoline).
Wear body protection made from leather or flame-resistant clothing (FRC). Body protection includes oil-free clothing such as
leather gloves, heavy shirt, cuffless trousers, high shoes, and a
cap.
Do not use fuel gases to clean clothes or work area.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding or cutting.
After completion of work, inspect area to ensure it is free of sparks,
glowing embers, and flames.
Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B
for hot work and have a fire watcher and extinguisher nearby.
CYLINDERS can explode if damaged.
Compressed gas cylinders contain gas under high pressure. If
damaged, a cylinder can explode. Since gas cylinders are normally part
of the welding or cutting process, be sure to treat them carefully.
D Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, and sparks.
D Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping. Do not lay acetylene cylinders on their sides or acetone will flow out of the cylinder
and damage the equipment.
Keep cylinders away from any arc welding, cutting, or other electrical circuits.
Never drape a welding or cutting torch over a gas cylinder.
Never weld or cut on a pressurized cylinder − explosion will result.
Use only correct compressed gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and associated parts in good condition. Do not use compressed gas cylinder unless an approved gas regulator is attached to the gas valve.
Turn face away from valve outlet when opening cylinder valve. Do
not stand in front of or behind the regulator when opening the valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Use the proper equipment, correct procedures, and sufficient number of persons to lift, move, and transport cylinders.
Store compressed gas and oxygen cylinders in separate locations.
Store empty cylinders with valves closed and caps in place.

SECTION 2 − INTRODUCTION
Inspect all equipment before use. Do not use damaged, defective, or improperly adjusted welding and cutting equipment.
Make sure levers and valves work properly, threads on equipment are clean (no grease or oil) and not deformed, gauges are
intact and easy to read, regulator is clean and free of oil or dirt,
and fittings are properly sized for the cylinder. Make sure
hoses are clean (no grease or oil) and ferrules are properly installed so the fitting does not slip inside the hose. Be sure all
connections are tight and there are no leaks in the system.
This booklet offers basic information regarding the Quickbraze torch systems. Given reasonable care, the torch will provide trouble-free use for
many years.
SECTION 3 − HAZARDOUS EVENTS
The following events are very hazardous and can occur in any oxy-fuel
system. It is important to understand these hazards and know how to
prevent them.
Backfire: The momentary recession of the flame into the torch, potentially
causing a flashback or sustained backfire. It is usually signaled by a popping
sound, after which the flame may either extinguish or reignite at the end of
the tip.
Sustained Backfire: The recession of the flame into the torch body with
continued burning characterized by an initial popping sound followed by a
squealing or hissing sound, potentially burning through inside the torch
body.
Flashback: The recession of the flame into the torch body with continued
burning characterized by an initial popping sound followed by a squealing or
hissing sound, potentially burning through inside the torch body.
SECTION 4 − ASSOCIATED HAZARDS OF
RECOMPRESSING PURE OXYGEN
Open oxygen cylinder valves slowly. Opening an oxygen cylinder valve quickly can cause a fire or explosion. Be sure regulator adjusting handle is in the full out (off) position before opening an oxygen cylinder valve.
Recompressing high pressure oxygen in a low pressure cavity may create heat, resulting in combustion. For combustion to occur, oxygen, fuel,
and kindling temperatures must be present. All of these components
may be present when oxygen is recompressed by opening the tank valve
too quickly.
OM-263507 Page 7
Oxygen: High purity oxygen accelerates the rate of combustion, increases heat output, and lowers the combustible point at which various
materials will burn.
Fuel: The fuel for combustion may be the regulator itself if enough heat is
produced to reach the kindling temperature of the regulator’s components.
Kindling Temperatures: Enough heat may be generated to ignite the
regulator components by the friction created when recompressing
high-pressure oxygen. This heat is known as the heat of recompression.
If an internal fire or sustained backfire occurs (indicated by a
whistling sound or inverted flame), do the following:
D Turn off the torch oxygen valve immediately.
D Turn off the torch fuel valve.
D Turn off the oxygen cylinder valve.
D Turn off the fuel gas cylinder valve.
Do not relight the torch until the equipment has cooled to the touch and
the sustained backfire cause has been determined and corrected.
SECTION 5 − THE TORCH SYSTEM
5-1. Torch
The torch is designed to meet the requirements of industry for a small,
lightweight torch to braze, heat, and solder tubing from 1/4 to 1-5/8 in. (6
to 41 mm) diameter. The various tips available provide a wide range of
flame configurations and the versatility to perform many different tasks.
Lightweight construction and highly flexible hoses provide pinpoint flame
control and ease of operation.
5-2. Gases
The torch system uses oxygen and these commonly available pressurized fuel gases: acetylene, hydrogen, propane, propylene, natural gas,
or gas with oxygen.
NOTICE − When using natural gas, a minimum of 1 psig (6.9 kPa) is required at the torch. Higher pressures may be necessary for use with multiple flame tips.
5-3. Tips
There is one standard tip, two twin flame tips, and one heating tip available.
Refer to the pressure recommendation chart provided in this booklet for the
tips being used.
5-4. Hose
Replace hoses at the first sign of any defects, flaws, or damage. The hoses should otherwise be replaced every four years.
Inspect hoses for damage or leaks before each operation. Do
not allow hoses to come in contact with hot metal, molten solder, or corrosive chemicals. Do not expose hoses to fluxing
agents as these agents will deteriorate the hose materials and
cause them to leak.
Use an approved oil-free leak detection fluid to locate possible
leaks.
Use only industrial grade hose. Grade T hose is acceptable for
all fuel gases. Grade R hose is for acetylene only.
OM-263507 Page 8
The torch hose supplied with the Quick Braze torch is made of a special
material designed to be compatible with the various fuel gases.
For your protection, use only genuine Miller hose and replacement parts.
Miller replacement hoses come with step-by-step replacement instructions and a tool for securing the brass ferrules over the hose ends.
Repairs and replacement parts are available through your Miller
authorized service agency.
SECTION 6 − USING THE TORCH WITH
DISPOSABLE-TYPE CYLINDERS
Inspect equipment before use. Do not use if grease or oil is
present on equipment or if equipment is damaged. Have equipment cleaned/repaired by a qualified person.
Do not slightly open or “crack” fuel cylinder valve to blow
