420258 - Hypertherm XPR 170A QuickLock Electrode for Mild Steel & Aluminum

High-Performance Electrode for XPR Systems

The Hypertherm 420258 is a specialized electrode engineered for the high-definition XPR170™ and XPR300™ plasma cutting systems. Designed to operate at 170 Amps, this consumable is critical for achieving optimal results when processing mild steel and non-ferrous materials, specifically aluminum. As a core component of the XPR consumable stack, it plays a vital role in maintaining the arc stability and energy density required for precision industrial fabrication.

This electrode utilizes Hypertherm's proprietary QuickLock™ technology. Unlike traditional threaded electrodes that require time-consuming alignment and multiple turns to secure, the QuickLock mechanism allows for insertion and removal with a simple quarter-turn. This innovation drastically reduces downtime during consumable changeovers, increasing overall equipment effectiveness (OEE) in high-volume production environments. The electrode is manufactured from high-grade copper to ensure efficient thermal management and electrical conductivity under high-amperage loads.

When used in conjunction with the correct nozzle and shield cap, the 420258 electrode supports the XPR system's ability to deliver X-Definition™ cut quality. This results in cleaner, sharper edges with consistent angularity throughout the life of the consumable. It is specifically rated for use with Air and Oxygen plasma gases, providing versatility for different shop requirements. By using genuine Hypertherm consumables, operators ensure their system operates within factory specifications, protecting the torch head from damage and maintaining warranty compliance.

The 420258 is strictly for mechanized applications and is not compatible with handheld torches or older generation systems like the HPR series. It represents the latest in plasma cutting technology, offering dramatic improvements in consumable life on mild steel applications compared to predecessor technologies.
