The Hypertherm 220948 FineCut Ohmic Shield is a specialized consumable designed for fabricators who demand the highest level of detail and precision from their automated plasma cutting systems. Engineered specifically for the Duramax mechanized torches found on Powermax 65, 85, and 105 systems, this shield is an integral component of the FineCut consumable stack. Unlike standard cutting shields, the FineCut series is optimized to produce a narrower kerf, stiffer arc, and virtually dross-free cuts on thin-gauge metals, bridging the gap between standard air plasma and high-tolerance laser cutting.
One of the standout features of the 220948 shield is its ohmic sensing capability. In mechanized CNC applications, maintaining the correct torch-to-work distance is critical for cut quality and consumable life. This shield is electrically conductive and designed to interface with Torch Height Controllers (THC) that use ohmic contact to detect the plate surface. By establishing a precise initial pierce height, the shield helps prevent torch crashes and ensures consistent cut geometry across uneven sheets of metal. This feature is essential for high-production environments where automation reliability is paramount.
This shield is rated for an operating range of 30 A to 45 A, making it the ideal choice for working with thinner materials where excessive heat input can cause warping or melting. When paired with the correct nozzle and electrode, the 220948 shield constricts the plasma arc to deliver sharp edges and fine details that standard consumables cannot match. Whether you are cutting intricate HVAC ductwork, artistic metal signage, or precision brackets, this genuine Hypertherm part ensures your Powermax system operates at peak efficiency.
Manufactured in the United States to Hypertherm's rigorous quality standards, the 220948 shield is built to withstand the harsh environment of plasma cutting. Its robust design resists spatter buildup and heat deformation, ensuring a long service life and reducing downtime associated with frequent consumable changes. Using genuine Hypertherm consumables not only guarantees the best cut quality but also protects your torch and system warranty.
