What is High-Speed Nozzle Design in Welding?

It is a high-pressure, divergent nozzle design that produces 10-15% faster cutting speeds than traditional welding nozzles. The high-speed nozzle has an operating range of 60-110 PSIG depending on the brand. This increase in cutting speed is due to the increased pressure and divergence which creates more focused energy on the workpiece.

What is High-Speed Nozzle Design used for?

This design is most commonly used in applications where precise, quick cuts are needed such as in sheet metal fabrication or pipe welding. The higher pressure and divergent beam also make the high-speed nozzle ideal for piercing through thick materials.

Advantages of High-Speed Nozzle Design

While the high-speed nozzle provides many advantages, it is important to note that it requires more skill to use than a traditional welding nozzle. This is due to the fact that the increased pressure and divergent beam can cause the arc to wander if not properly controlled.

Oxy-acetylene cutting nozzle sizes

The nozzle size you need depends on the thickness of the metal you are cutting:

  • 0-3 for thin metal.
  • 3-7 for medium thicknesses.
  • 7-10 for the heaviest metals.

Threaded MIG nozzle sizes

The MIG nozzle you need will depend on three factors:

  • The welding wire diameter.
  • The shielding gas.
  • The joint configuration.
