The Hypertherm 003149 is an industrial-grade electromechanical pilot arc control relay designed for plasma arc ignition and control tracking systems. It functions as a dedicated line replacement for high-capacity automated mechanized plasma cutting infrastructure, specifically regulating the initial high-frequency ionization arc before transfer to the workpiece.
Features
Anti-Weld Contact Design: Silver-cadmium chemical properties resist electrical pitting, arc erosion, and contact welding under high-current inductive surges
Dual-Pole Isolating Separation: 2PDT logic allows simultaneous control of two independent circuits for concurrent pilot loop activation and status feedback
Rapid Duty Sequencing: Mechanical action speeds synchronized with gas pre-flow and gas post-flow intervals
High-Dielectric Thermal Defense: Housing designed for localized thermal protection and resistance to carbon tracking
