The ESAB 21-1075 (0559211093) is a hafnium-insert electrode designed for mechanized plasma cutting of mild steel. It serves as the electrical arc emitter within Thermal Dynamics XT-300 and Ultra-Cut XTL series torch systems, utilizing a copper body for thermal conductivity during high-amperage operations.
Features
High-conductivity copper body for heat dissipation from the hafnium insert
Hafnium emissive insert for plasma arc generation
Stable arc attachment point for consistent kerf width and cut angularity
OEM component design for dross-free edges and verticality
Predictable erosion patterns for proactive maintenance scheduling
Rated for continuous operation at 200A to 250A amperage ranges
