OVER 50 YEARS OF SAFFIRE – THE SAFE REVOLUTION
Murex Welding Products Saffire brand celebrated its 50th anniversary
in 2006. Since the introduction of the first Saffire nozzle mix gas welding
and cutting system, the brand has become synonymous with absolute
safety in all aspects of oxy-fuel welding and cutting.
1956 was the debut year of the Saffire nozzle mix gas welding and cutting
system, which fundamentally rewrote the principles and working methods of
gas mixing along the lines of safety.
The idea of using a nozzle mixing, high-pressure system was quite well
known at the time, but although its safety advantages were recognised,
Saffire was the first to put it into practice.
Consequently, Saffire was enormously successful from day one. A market
leader from the start, Saffire has grown and changed with improvements
since then, but the principle – Safety First – has always been the motivating
force behind all developments.
One of the immediate effects Saffire had was the simplifying of the oxy/fuel
welding and cutting procedure, and by making the equipment virtually
maintenance free, we had also ensured that mixing and handling two of the
most reactive gases known was no longer a high-risk operation.
In 1966 the new innovative blowpipe, Saffire 3, won a Design Centre Award.
The original Saffire nozzle mix gas welding and cutting blowpipe has today
evolved in the Saffire 5. In 2005 is was estimated that there could have been
as many as half a million in use throughout the world. Versatility in use and
on-going product developments have been instrumental to the success of
the Saffire brand. Its application area is immense throughout all sectors of
industry and it can be used for heating with acetylene and propane, flame
cleaning, rivet cutting, circle cutting, gouging and sheet cutting. It is a
system that provides a solution for so many jobs on a day-to-day basis in
the workplace.
From the original nozzle mix system, the Saffire gas product range has been
dramatically developed to embrace flashback arrestors, regulators and other
devices all synonymous with Safety First. Today flashback arrestors are
fitted to all oxy-fuel welding/cutting systems and the use of this product is
universally recognised as good procedure by Health & Safety Executives and
factory inspectors. All Saffire products are now supplied under the quality
management system of BS EN ISO 9001.
Saffire was, and still is, a truly earth shaking revolution – and it remains the
safest yet. As we’ve said since 1956, “Make it Saffire, Keep it Safe.”

Saffire 300 Series 2+ Multi-Stage Regulators
The Multi-stage series employ the principles of 2-stage gas control
to provide precise and accurate delivery pressures under all
conditions. This ensures the regulators are able to cover a full range
of service requirements from fusion welding through to high integrity
laboratory applications.
The Saffire 300 Series 2+ regulators are the flagship models of the Saffire
range. These multi-stage regulators are fully 300 bar capable whilst retaining
the sensitivity and accuracy necessary for precise control.
The regulators are fully compliant and certified to BS EN ISO 2530.
As with all Saffire products these are manufactured under the quality
management systems of BS EN ISO 9001.
• 1st stage reduces the inlet pressure allowing very accurate adjustment
through the 2nd stage
• Fully compliant and certified to BS EN ISO 2503 with quality
management to ISO 9001
• High strength brass body with operational data permanently engraved
• High specification safety device to protect the user
• Full 300 bar inlet capability
• Solid bulkhead gauges
• Stainless and Neoprene diaphragms
• KelF micro valve in first stage
• Broad seat A92 valve in second stage
34
Laboratory Regulators
The Saffire Laboratory range provides
both top and side entry connections
to accommodate different cylinder
valves. All components are purpose
designed for non-corrosive high
pressure gas service.1st stage
diaphragm is coated stainless steel
for high integrity leak tightness
needed for “light” gases.
NEVOC Regulator
The trend in Europe to increased
cylinder filling pressures has led to
the adoption of a separate cylinder
valve connection for industrial
applications above 250 bar.
The connection is designated
“NEVOC” – New European Valve
Outlet Connection. In practice
cylinders filled above 250 bar and
up to and including 300 bar will be
fitted with NEVOC valves. Cylinders
filled up to and including 250 bar
will continue to use the standard
BS 341 connection. This change
will have the added benefit of being
adopted across Europe.

Shielding Gases
The range provides for both MIG and TIG variants based on the
BS EN 13918 : 2003. Both units are calibrated to ensure maximum gas
efficiency for the gas shielded arc welding processes.
• Purpose designed for process
• Full 300 bar inlet capability
• Metered outlet orifice coupled with a highly efficient flow gauge gives
accuracy and therefore economy when MIG welding
• Factory calibrated and quality managed through ISO 9001 system
Arc-35L & Co2-35L
These two gauge single-stage regulators will cope with the majority of
MIG/MAG welding applications and are small enough to sit within the
circumference of the cylinder. Fitted with a flow gauge instead of the
vulnerable bobbin type flowmeter, they have proved themselves ideal in the
very rugged situations this equipment often has to withstand.
Ar-2TIG
This single-stage regulator has been preset at 2 bar (30psi) to give a constant
performance. It has been designed specifically for Argon-Tig welding and can
be used by itself or with a bobbin type flowmeter.
Argoshield Arc-40L
Proved to be the most economic regulator for use with Argon and Argon
mixtures. The two stage design eliminates the pulsating of gases which is so
wasteful. It will overcome the problem in the most economic and efficient
manner. Fitted with a flow gauge which is coloured to indicate recommended
flow rates, this regulator will cope with heavy duty service where high flow
(up to 40L/M-80ft3/hr) is required. The two stages and large diaphragm greatly
reduce the possibility of freezing.

Saffire MK4 Gas Economiser
This device provides economy in the use of gas in welding operations up to
nozzle size 25. During non-welding periods the blowpipe can be hung safely
on the hooked lever which operates the gas shut-off valves in the economiser.
Saffire CO2 Heater
Specifically designed for use with Carbon Dioxide this unit allows flows of
up to 40cfh without the risk of freezing or noticeable changes in the flow or
pressure. They are available in 230V, 150 Watt versions.
Flowmeter
The vantage flowmeters are damage resistant tough poly carbonate with solid
brass body and fittings. Two models are available, which are designed for use
with the MIG or TIG process.
• Calibrated flow at 0 – 15 or 40 litres/minute

All Saffire Cutters are equally suitable for Acetylene and Propane service simply by
changing the nozzle.
Saffire cutters have the benefit of a unique cutting oxygen flow valve which through
the cutting lever acts indirectly to bring in the oxygen stream. This important feature
gives a true “bleed” characteristic to create splash free starts and progressive
piercing and the smoothest possible cutting conditions.
Saffire NM Cutters are designed to BS EN 150 5172 “Handheld Blowpipes for

PNM – Cutting Nozzles
Propane Superheating Nozzles
Saffire PNM Series cutting nozzles are of two piece design made
up of a brass inner nozzle with splines and a hollow drawn copper
outer sheath. The reason that PNM’s differ from ANM is that different
gas mixing criteria apply. Oxy-propane has a lower burning velocity
than oxy-acetylene and this requires two things to develop good
flame conditions. First, turbulence must be
created between the inner and outer parts
of the nozzle to obtain adequate mixing of
the propane and oxygen. Secondly, the
volume of mixed oxy-propane needs to be
more than double that of oxy-acetylene for
the same usable heat. This is achieved by
having very large channels (the splines) to
conduct the greater gas volumes.
The “H” Series are designed to provide a large flame giving a
broad spread of heat over a large area. The nozzles are widely
used for pre and post heating of
weldments and for the shaping
and forming of steel components.
There are 5 models in the range
provide a range of flame sizes.

PROCESS NOZZLES
Acetylene Gouging Nozzles
AGNM nozzles employ the nozzle mix principle for gouging.
In application the nozzle cuts a “U” shaped groove in the plate.
The most common use is to “back gouge” butt welds to remove any
defects prior to laying the final sealing run.
They also find application in the removal of
defective welds or flaws in steel plates.
The use of oxy-acetylene allows for high
speed cost effective production. There
are 3 models in the range each providing
a “U” groove of different dimensions.

Safety Devices
Saffire 36ec Flashback Arrestors
Flashback Arrestors are essential safety devices which provide the
maximum protection for the operator and his equipment in the event
of a flashback.
A flashback can be caused by a variety of conditions such as sustained
backfire, incorrect hose purging or simply the wrong gas pressure. Most are
attributable to operator errors.
When a flashback occurs the flame front and pressure wave retreat into the
blowpipe and hose at a very high speed. This can cause detonation within the
system. It is essential that the regulator and more particularly the cylinder are
protected from the effect of a flashback.
The well proven 36ec conforms to the requirements of BS EN 730-1. The unit
offers comprehensive protection from the dangers of flashback and has the
following important safety features:
• Reset Button – this is protected
within the body of the unit to
protect against damage. Very
important. The “pop-up” feature
indicates when a flashback has
occurred and the arrestor
activated. Simply lift to reset
• Sintered Metal Flame Arresting
Element – very large diameter with
extensive surface area – designed
to arrest the flashback flame
quickly. The element size is
important to long service life and
to allow high flow use
• Non-return Valve – upstream of
the flame arresting element
ensures no gas can backfeed to
ignite incoming gases
• Thermal Cut-off Device –
designed to completely isolate the
system by cutting off all incoming
gases in the event of a fire
• Pressure Sensitive Cut-off Valve –
in the event of a flashback the
pressure wave will activate the
valve to cut off the gas supply
automatically
48
R
Indicator button
In normal operation a
green safety band shows
around the button. After a
flashback the band does
not show and the outer
shroud must be lifted to
reset the unit.
Non-return valve
Upstream of the flame
arresting element, this unit
ensures no gas can
backfeed and ignite
incoming gases.
Sintered metal flame
arresting element
Extensive surface area
designed to arrest a
flashback flame quickly.
The element surface area
is important to ensure
long service life and to
permit high gas flow in
normal operation.
Pressure sensitive
cut-off valve
In the event of a
flashback the pressure
wave will activate the
valve to cut off the gas
supply automatically.
In the event of a flashback
the flame front strikes the
retaining plate thereby
displaying much of the
flashback force. The flame
front passes into the
absorbtion chamber and is
quenched as it enters the
flame arresting element.
The following pressure wave
passes through the filter
and activates the flow cut
off valve by its pressure.
This causes the reset button
to move downwards.
This equipment is thus
rendered safe with the
flashback flame extinguished
and the incoming gas
supply stopped.
Thermal cut off device
Designed to cut off the
gas in the event of
extreme temperatures
such as a hose fire. The
unit is activated at 95ºC.
