What is the purpose of each plasma consumable?

Secondly the electrode conducts high voltage or high frequency (HF) energy during the initial start of the cut. This adds electricity or energy to ionize the cutting gas, creating plasma and allowing the arc to start. Features of an Electrode. The Hafnium emitter or insert, is the most critical component. This allows for HF to start the arc.

1/18/2012· A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice.

Consumable inspection visual aid - Hypertherm

Even with little use, it is normal for an electrode to show marks and discoloration. Make sure the o-ring(s) feel flexible and lubricated at all times. Heat can affect o-rings after use. The hafnium insert should not lose its circular shape and should be fully centered. The hafnium is eroded, but copper is intact. Color is dark, and/or white.

Plasma Cutting Consumables: What, Why, and How Long …

As the electrode produces the arc, the hafnium insert melts and over time fragments are shot out through the torch in the cutting process, resulting in the development of a pit in the end of the electrode. This is perfectly normal, but when the pit grows deeper than around 1-1.6 mm you'll need to replace the electrode, as there won't be much hafnium left, and you'll soon start burning ...
