Plasma Torch Retaining Cap Damage Causes: Heat, Double Arcing, Loose Caps, and Wrong Consumable Stack
If a plasma torch retaining cap is melted, cracked, burned, cross-threaded, stuck, discolored, or causing torch-cap faults, stop cutting and inspect the full consumable stack. The retaining cap holds the electrode, swirl…

Plasma Electrode Pitting Causes: Air Quality, Gas Pressure, Amperage, Standoff, and Consumable Wear
Plasma electrode pitting is normal wear until the pit becomes deep, off-center, or rapidly destructive. The electrode contains an emitter insert that erodes during cutting. A small centered pit is expected. Fast…
