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 

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-80ft 3 /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 CO 2 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.

5 Cutting Attachment 

Designed to cope with the rigours of the modern welding and 

fabrication environment, the robust Saffire 5 cutting attachment offers 

a host of features including a cutting oxygen valve which allows more 

control of the cutting oxygen flow for improved cut quality. 

The gas tubes between the body and head are in line, giving maximum 

visibility of the working area, also connections between the gas tubes and 

the head and body of the cutting attachment are brazed for increased 

strength. The head itself is equipped with internal threads for the head nut 

which greatly reduces the risk of thread damage, and finally the whole of the 

cutting attachment has a chrome finish to increase heat reflection and reduce

B.S. Note: Where applicable blowpipes and 

nozzles are designed and manufactured to 

comply with BS EN 150 5172. 

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 

Welding and Cutting” and manufactured under the quality management systems 

of BS EN ISO 9001. 

NM 250 

The NM 250 Model is principally intended for general workshop cutting up to 

250mm (10") capacity. The balance and trim combined with 500mm (18") length 

make it ideally suited for most industrial applications.

CUTTING NOZZLES 

Acetylene Nozzle Mix – ANM 

Saffire ® ANM Series cutting nozzles are manufactured from 

Tellurium Copper and are of solid, one piece drawn construction. 

This technology provides the best conditions 

for a high velocity gas such as acetylene and 

enhances stability and cutting efficiency. 

The seats of ANM nozzles are diamond 

turned to guarantee “metal to metal” seal 

with the blowpipe head. This is essential to 

ensure no head seat leaks, thereby 

reducing backfire risks.

PNM – Cutting 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.

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. 

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. 

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. 

Saffire XL5 Flashback Arrestors 

The Saffire ® XL cylindrical flashback arrestors, are of advanced design giving 

a higher flow rate. Internally the XL is equipped with a large cylindrical flame 

arresting element, an automotive reset non-return valve and a heat sensitive 

automatic cut-off. 

• Automatic reset non-return valve 

• Heat sensitive cut-off valve 

• High flow flame arresting element 

• Inlet filter for internal mechanism 

• Conforms to BS EN 730-1 

Saffire Hose Check Valves 

A vital piece of equipment protecting against 

backfeed. The Murex hose check valve is a 

self-aligning non return valve which Is spring 

loaded and detects reverse gas flow; it 

automatically closes, therefore preventing the 

conditions which lead to flashback. Conforms 

to BS EN 730-2.
