Trafimet PR0110 is the electrode used on the S45 plasma torch, which is also fitted to many 40 A inverter plasma cutters. This is an aftermarket part made to the same number and fit, for air plasma cutting.
Copper body with a hafnium insert at the tip, where the arc attaches. It wears with every start, so electrodes are bought in packs and changed together with the nozzle.
Check the number on your old part or in the torch manual before ordering: it should read PR0110. Sold in packs of 10 or 20.

Routine changes
The electrode is the fastest wearing part in the torch. Change it when the hafnium insert has a pit deeper than about 1.6 mm (1/16 in), when the arc starts to wander or the cut bevels, and always change the nozzle at the same time.
Keeping cut quality
A worn electrode makes the arc harder to start and widens the kerf. Fresh electrode and nozzle pairs keep the cut square and the dross low.
