The Hypertherm 220666 is a 200-amp SilverPlus bi-metal electrode engineered for mechanized plasma cutting systems. It utilizes a patented silver-hafnium interface at the point of electrical transfer to enhance heat extraction and increase the allowable pit depth before failure, specifically designed for mild steel cutting applications.
Features
SilverPlus technology incorporates a hafnium/silver interface for superior heat dissipation
Service life rated at minimum 2x longer than standard copper electrodes
Stronger metallurgical bond between silver and hafnium compared to copper and hafnium
Facilitates deeper burn capacity (2.0 mm) before replacement is required
Reduces the number of consumable sets used over time
Decreases frequency of torch maintenance and consumable changeouts
Maintains cut quality for longer durations compared to standard consumables
Designed to withstand 20% programmed ramp down errors during operation
