ARCNM Special Bulkhead Cutting Angled Nozzle with Single Flat Edge and 3 Pre-heats
Many artisans will know this specialist cutting nozzle as the ARCNM , the traditional UK version was only available in a single size and had just two pre-heating flame cones. At Noz-Alls we have chosen this Nozzle as it provides improved performance and is typically easier to use.
This ARCNM nozzle is bent to facilitate removal of bolt heads, rivet heads and protrusions from a surface allowing plates to be taken apart reworked and joined once more.
Compared to the traditional curved ARCNM this design facilitates the easy removal of a bulkhead without "scarring" the other side. Running the flat edge of the nozzle across the base material ensures the cutting stream remains parallel to the base. Once the bulkhead has been removed there is very little material left to be cleaned (ground) away.
Do NOT tilt the nozzle in use otherwise scarring will occur resulting in more rework.
This ARCNM cutting nozzle has 3 pre-heat flames instead of just 2 on the original ARCNM, the 3 pre-heat flames help to improve the cutting performance which makes the ARCNM nozzle far more useful, plus this nozzle is available in 4 sizes.
The 4 sizes are available to cut from 3mm through to 100mm thickness:-
Size #1 Cutting thickness ability 3 - 25mm
Size #2 Cutting thickness ability 15 - 50mm
Size #3 Cutting thickness ability 40 - 80mm
Size #4 Cutting thickness ability 50 - 100mm
The larger nozzle sizes need to operate from a large industrial acetylene cylinder due to the withdrawal rate of the acetylene. Please remember that having only 3 pre-heats does mean that cutting on material bulkheads of 30mm thickness or more cutting progress is slower than a normal nozzle due to the reduced heat input and the conduction.
Bolt heads, Rivet heads or fixing nuts are normally much easier to process and cut at normal speeds because the heat transfers into the "bolt heat / nut" with less being conducted away.
