ANME-6 Cutting Nozzles - Full SIze Range Available From 0,8 (1/32") to 3,2 (1/8")
The ANME-6 are more frequently used in cutting machines in the UK .
The longer length of the ANME improves the backfire resistance when compared to the 1/2" shorter ANM-6.
Our ANME cutting nozzles are manufactured to our engineering drawings to ensure you may be confident the nozzle has the correct flame characteristics and is safe to use.
The problem is that many nozzles may look similar but they are not, it is how the nozzle has been manufactured inside that counts.
The ANME -6 was the original ANM cutting nozzle, it was a cost cutting exercise by BOC which produced the shortened (76mm) ANM as we know it today the original nozzle length then became the ANME for "extended".
At a later date the nozzle body diameter of the ANME was reduced to the European standard of 15mm. The Noz-Alls range of cutting nozzles provides you with the full range of sizes, unlike all the other suppliers, the ANME-6 cutting nozzle is available in the full range of sizes to maximise your cutting efficiency. 1/32", 3/64", 1/16", 5/64", 3/32", 7/64" & 1/8".
Cutting range for the ANME-6 is as follows:-
0.8mm 1/32" 3-6mm Operates safely on a single large DA cylinder
1.2mm 3/64" 5-12mm Operates safely on a single large DA cylinder
1.6mm 1/16" 10-75mm Operates safely on a single large DA cylinder
2.0mm 5/64" 70-100mm Operates safely on a single large DA cylinder
2.4mm 3/32" 90-150mm Operates safely on a single large DA cylinder
2.8mm 7/64" 140-200mm Needs to operate with 2 large DA cylinders
3.2mm 1/8" 190-300mm Needs to operate with 2 large DA cylinders
Oxy / acetylene will always be the best and safest gas to cut with, no other fuel gas can match the ability of oxy/acetylene to impart its heat quickly and efficiently into the work plate to be cut so the ignition time with oxy/acetylene is always the shortest, one of the "problems" is having artisans set a pre-heat small enough, the oxy / acetylene flame is so efficient you don't need a large flame, as the large flame causes "problems" such as welded on dross on the bottom edge, top edge melt and concave cut. Reduce the flame size / amount of heat and the problems go away! Class 1 cut without any problems.
From a safety point of view working with oxy/ acetylene is good as the acetylene is lighter than air and readily disburses into the atmosphere which is different to the heavy LPG gases such as Propane or Propylene which don't burn so readily, are much heavier than air and will collect and remain in voids / pockets as a danger for later.
Working with Oxy / Acetylene uses just a quarter of the oxygen that propane requires for burning the pre-heat.
Oxygen purity will affect the cutting speed with which a nozzle can function, not the fuel gas, no one fuel gas cuts faster than another and anyone that says so is being miss leading. The Oxygen does the cutting and the pre-heat is there to maintain the ignition spot. The fastest fuel gas to give an ignition spot is Acetylene while one of the least efficient is Natural Gas. When set correctly every fuel gas is capable of providing class 1 cut face finish at the same cutting speed when using the same cutting orifice characteristics. When your cutting involves frequent stop starts then oxy / acetylene will save time and money because oxy/acetylene achieves your ignition spot first and most efficiently using lots less oxygen.
Oxy / Acetylene - Safe & Efficient - Safe to work with safe to store and use - Put oxy / acetylene back at the top of your list.
Why Its Important to Pay the Right Price
When you pick up an ANM-6 in your hand what do you see, is it just a lump of copper with 20 holes in it with 10 external diameters and 3 tapers?
Well typically that is what you see when you examine an ANM no matter whose ANM or ANME cutting nozzle you have purchased.
Very few people have sufficient experience to understand nozzle design and that although the external dimensions are important for most of those dimensions it is the internal sizes that dictate nozzle performance and those you cannot see.
Have you ever considered what makes the ANM-6 cutting nozzle function and operate correctly? Well it all comes down to the internal design and manufacturing process, that is what determines just how the nozzle performs it is the arrangement of the internal holes and their sizes that makes all the difference to each nozzle.
Inside each ANM-6 there are 33 different diameter holes 6 individual mixing systems each of 5 different diameters and those hole diameters each interacting with the other to help provide the correct flame characteristics.
The design is not particularly difficult to achieve when made correctly however it is important for the design to be correct.
How do companies make cheap ANM nozzles, well to cut the cost of the nozzle – they simply take out some of the internal operations and hole diameters.
Due to the fact the changes are made internally you cannot see the cheapening of the nozzle.
To the untrained eye removing operations which may seem to be superfluous result in an inferior nozzle with poor performance when it counts.
Less processing means less operations and less cost in manufacturing with quicker processing resulting in a cheap nozzle.
Externally the result looks the same and you would never know as the inside goes unnoticed until the nozzle doesn’t work correctly.
