220818 - Hypertherm 220818 Duramax Drag Shield 15-85A for Powermax 65/85

Genuine Hypertherm 220818 Drag Cutting Shield for Duramax Torches

The Hypertherm 220818 is a high-performance drag cutting shield engineered for use with the Duramax and Duramax Lock series of handheld plasma torches. This consumable is a critical component for operators utilizing Hypertherm Powermax systems, specifically the Powermax45 XP, Powermax65, Powermax85, and Powermax105. Designed to operate effectively across a broad amperage range of 15 to 85 amps, this shield facilitates direct contact between the torch and the workpiece, a technique known as drag cutting.

Technical Superiority and Design

Hypertherm's patented consumable technology is at the core of the 220818 shield. Unlike standoff cutting, which requires the operator to maintain a precise distance from the metal, this shield is electrically isolated and constructed to withstand the heat and spatter of direct contact. This design stabilizes the arc and protects the inner nozzle from molten metal blowback, which is a common cause of premature consumable failure. By maintaining a consistent distance between the nozzle orifice and the workpiece, the shield ensures optimal arc constriction and energy density.

Operational Efficiency

Industrial environments demand efficiency and reliability. The 220818 shield contributes to lower operating costs by extending the life of the electrode and nozzle. Its robust construction resists wear and minimizes dross accumulation, leading to cleaner cuts that require less secondary grinding or preparation. For fabrication shops handling varying thicknesses of mild steel, stainless steel, or aluminum, the ability to switch between 15A and 85A output without changing the shield type (within the drag cutting setup) offers significant versatility.

Compatibility and Specifications

This shield is strictly for handheld torch applications. It is fully compatible with the standard Duramax 75-degree and 15-degree hand torches, as well as the Duramax Lock torches found on newer Powermax models. It is not intended for mechanized machine torches. When properly installed, the 220818 ensures that the plasma gas flows correctly to cool the consumables and shape the arc, delivering the cut quality Hypertherm is famous for.
