To fit a nozzle on an NM cutting torch, remove the head nut and install a NM heating nozzle adaptor before reinstalling nut.  Screw the propane heating nozzle onto the adaptor.  A higher heat output is achieved with an NM torch set up.

To fit to a heavy duty / type 5 shank:  Fit a type 5 propane heating mixer to the type 5 shank and a propane heating neck screws into the mixer.  The nozzle screws onto the end of the swan neck.


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 – orange for propane 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.
  • All our super heating nozzles are castellated for safety and may be touched down without fear of flame retraction / equipment damage.
  • Correct setting of these nozzles is vital to ensure the fuel is burnt correctly.
  • Avoid a soft flame, if you have too much heat change to a smaller size.
