220649 - Hypertherm HPRXD 130A Mild Steel Bevel Electrode (5-Pack)

Technical Overview of the Hypertherm 220649 Electrode

The Hypertherm 220649 Electrode is a specialized consumable component engineered specifically for high-amperage beveling applications on mild steel. Designed to operate at 130 Amps, this electrode is a critical part of the torch assembly for the HyPerformance® HPRXD® family of plasma cutting systems. It is fully compatible with the HPR130XD, HPR260XD, HPR400XD, and HPR800XD machines, as well as legacy HPR130 and HPR260 systems when configured for bevel cutting. The electrode functions as the primary emitter of the plasma arc, requiring precise geometric tolerances to maintain arc stability and focus during the demanding conditions of beveling.

Manufactured from high-grade copper, the 220649 electrode features an insert designed to withstand the thermal and oxidative stresses associated with oxygen plasma cutting. The internal cooling geometry is optimized to dissipate heat efficiently, preventing premature failure and ensuring consistent performance throughout the life of the part. In a mechanized plasma torch, the electrode works in conjunction with the nozzle, swirl ring, and shield to shape the plasma jet. For bevel applications specifically, this electrode is calibrated to support the angled torch orientation and the specific gas flow dynamics required to produce smooth, accurate beveled edges on mild steel plates.

Proper installation and timely replacement of the electrode are vital for maintaining cut quality and protecting the torch head. As the electrode wears, the hafnium insert erodes; operating the system beyond the recommended wear limit can lead to catastrophic failure of the consumable stack and potential damage to the torch body. This product is supplied in a pack of five, allowing operators to maintain a ready stock of replacements for continuous production schedules. It is strictly rated for 130 Amp processes and should be matched with the corresponding nozzle and shield cap for optimal results.
