The Hypertherm 220673 Shield is a precision-engineered consumable designed specifically for the Powermax 45 plasma cutting system equipped with the T45v hand torch. As a critical component of the torch's front-end assembly, this shield plays a vital role in the patented Hypertherm consumable stack, ensuring optimal arc stability and cooling. It is rated for 45 Amp applications and is specifically configured for drag cutting operations.
Constructed to Hypertherm's rigorous OEM standards, the 220673 shield features advanced heat-resistant materials and precise geometry. Its primary function is to protect the inner nozzle from the intense heat and molten spatter generated during the plasma cutting process. By isolating the nozzle from the workpiece, it prevents 'double arcing' which can instantly destroy consumables and damage the torch head. The shield also directs the secondary gas flow (shield gas) around the plasma arc, which constricts the arc for higher energy density and cleaner cuts while simultaneously cooling the nozzle.
This shield is essential for operators utilizing the drag cutting technique, where the torch tip is placed in direct contact with the metal. This method is preferred for its simplicity and ability to follow templates or straight edges without the need for a standoff guide. The 220673 ensures that the proper standoff distance is maintained internally, protecting the nozzle orifice even during contact. Regular inspection and replacement of the shield are recommended to maintain cut quality; a damaged shield can lead to turbulent gas flow, reduced cutting speed, and increased dross levels.
Compatibility is strictly for the original Powermax 45 system using the T45v torch. It is not intended for use with the newer Powermax 45 XP Duramax Lock torches or mechanized T45m setups requiring non-contact shields. Trusting genuine Hypertherm parts ensures that your system operates within its factory specifications, providing the reliability and efficiency professionals demand.
