The ESAB Thermal Dynamics 21-1308 is a 400A mechanized plasma cutting electrode designed for high-precision mild steel applications using oxygen (O2) plasma gas. It is engineered for use with XT300 and XT301 torches within the Ultra-Cut (UC) series systems, featuring a hafnium-core copper construction to facilitate arc constraint and edge quality in automated CNC environments.
Features
High-amperage performance for material removal at 300A and 400A
Optimized for mild steel cutting to produce precise cuts
Durable construction for extended service life and reduced replacement frequency
Stable arc control for minimal dross and consistent quality
Universal compatibility with multiple Thermal Dynamics plasma cutting systems
Enhanced arc constraint for mechanized applications
