Description

ASNM NOZZLE FOR OXY ACETYLENE CUTTING OF THIN MATERIALS

An ASNM (Sheet Metal) nozzle for oxy acetylene cutting. The ASNM (Acetylene sheet nozzle mix) nozzles are designed to fit a cutting attachment on a Type 5 shank. They allow the user to perform neat and controlled cuts in thin sheet materials.

Key Features

One piece ASNM cutting nozzle
For cutting 0.8mm – 3.0mm materials

ABOUT ASNM NOZZLES

To fit a nozzle, the head nut is removed from the cutting torch or attachment, inserted into the seat and the nut is re-applied and tightened.

An ASNM nozzle has a hole configuration to allow a precise jet of oxy acetylene mixed gas to pre heat the metal to its ignition temperature. The other orifice expels a jet of oxygen to blow away the molten material, piercing the material and creating the cut.

When selecting a nozzle for your cutting application it is worth getting the size applicable to the material thickness to be cut. An oversize nozzle wastes gas.

Other Information:

Hoses being used with the torch should be the correct type for the gas and fitted with check valves (non-return). They are colour coded according to the gas they are designed for – red for acetylene and blue for oxygen.
Flashback arrestors should be installed on the regulator side of the hose.
A nozzle should be inspected regularly to check for damage or obstructions.
A poorly maintained nozzle can cause turbulent gas flow and increases the risk of flashback.
Obstructions to the nozzle can be caused by dirt or spatter.
Do not hold the nozzle too close to the workpiece. The nozzle can overheat and cause a flashback.
