The Hypertherm 428978 is a specialized robotic torch lead bundle designed for the XPR X-Definition plasma cutting platform. This 6-meter umbilical assembly facilitates the delivery of electrical current, pilot arc signals, multiple gas types, and liquid coolant to the torch head during automated multi-axis movement. It features a high-flex construction specifically engineered for robotic beveling applications where constant torsional and flexural stress occurs.
Features
EasyConnect™ Technology: Toolless, one-handed physical coupling for rapid torch or lead changes.
High-Flex Robotic Construction: Rated for continuous multi-million cycle automated twisting and articulation.
Vulcanized Outer Jacket: Abrasion-resistant polymer blend resistant to ozone, metallic spatter, industrial oils, and UV light.
Torsional Tolerance: Internal components glide within a low-friction housing to prevent kinking and internal friction wear during beveling.
Arc Response Technology™ Synergy: Integrated signal lines for microsecond telemetry to the power source for controlled ramp-down.
Gas Density Maintenance: Internal gas lines maintain wall tolerances under sharp bends to prevent volumetric starvation.
Pilot Arc Lead: Dedicated insulated secondary conductor for high-frequency arc initiation.
Strain Relief Boot: 0.5-meter robust boot at the torch interface to manage mechanical bend radius.
