A cutting torch head is used to cut materials. It is similar to a welding torch, but can be identified by the oxygen blast trigger or lever. When cutting, the metal is first heated by the flame until it is cherry red.
Cutting nozzles are precision-machined and hand-finished to give a positive seat. The orifices are swaged to minimise gas turbulence and slag accumulation, whilst the nozzle design provides excellent gas-mixing for fast pre-heating
