Torch Consumables

The torch is a T45m hypertherm machine torch.

Standard

  • Deflector P/N: 2206732
  • Retaining Cap - Ohmic P/N: 220719
  • Nozzle P/N: 220671
  • Electrode P/N: 220669
  • Swirl Ring P/N: 220670

Fine Cut

NOTE: These parts are for a t30 unshielded torch, they are compatiable with the T45m when it is run at a setting lower than 30A and cutting materials thinner than 3/16". Ohmic sensing will not work with these parts installed.

  • Deflector P/N: 2206732
  • Retaining Cap - Ohmic P/N: 220483
  • Nozzle P/N: 220480
  • Electrode P/N: 220479
  • Swirl Ring P/N: 220478
