The Hypertherm 120447 is an industrial-grade plasma arc consumable designed for automated plasma scoring, scribing, and layout operations. It functions as the cathodic termination point for pilot and transferred arcs within the ArcWriter multi-gas plasma marking system, supporting multi-gas configurations including Air, Argon, and Hydrogen blends.
Features
Thermal gas dynamics operation prevents clogging in dusty, high-humidity, or damp environments
Surface contaminant tolerance allows marking through wet, oily, or scale-covered plates without preparation
Pneumatic safety alignment integrates with internal cap sensors to cut power if the retaining cap is loosened
Dual-gas versatility for switching between Argon/Hydrogen layout lines and Air-plasma character scoring
High-conductivity copper body provides low thermal resistance path to cooling wells
Silver-brazed interface maximizes thermal transfer rates to prevent core blowout during current adjustments
