The Thermacut 220948 Plasma Shield is a crucial component for Hypertherm® Powermax® 65, 85, and 105 systems, built for use with the DURAMAX® torch. The standard 45A shield is designed for general cutting applications, providing a robust defense for the torch consumables while maintaining optimal arc stability. Ohmic sensing enables precise torch height control by detecting contact with the workpiece, and FineCut® technology is engineered for detailed, low-amperage cutting — producing a narrower kerf and cleaner edge, ideal for thin materials and intricate designs. Each shield protects the internal components of the torch, extends consumable life, and helps ensure consistent, high-quality cuts. Keep your Powermax® system running at its best — order genuine-fit Thermacut 220948 shields from MapleWeld today.

Frequently Asked Questions
This is a mechanized-torch shield for Hypertherm's Duramax torch series, rated for 30–45A and built for FineCut® applications — fine, detailed cutting on material roughly 3/16" and thinner, where a narrower kerf and stiffer arc matter. It's a genuine-fit replacement, not an original-equipment claim, unless purchased directly from Hypertherm.
It's specifically for mechanized Duramax torches, not the handheld T-series torches. If you're running a hand torch (like a T45v) on your Powermax system, this is not the correct shield — mechanized and hand-torch shields are not interchangeable.
It's compatible with Powermax45 XP, Powermax65, Powermax85, Powermax105, and Powermax MRT systems, used with the Duramax and Duramax LK/RT mechanized torch series.
Ohmic sensing lets the mechanized torch detect contact with the workpiece electronically for automated torch height control. This shield is built for Ohmic-sensing setups, so it's the correct choice if your mechanized system uses Ohmic height control rather than a different sensing method.
FineCut® is Hypertherm's configuration for fine, detailed plasma cutting — it produces a narrower kerf and a stiffer, more focused arc, intended for material around 3/16" and thinner. A standard (non-FineCut) shield is the better choice for general-purpose cutting on thicker material, where FineCut's fine-detail advantages aren't as relevant.
30–45A, per Hypertherm's own product listing.
It shields and helps cool the nozzle from molten spatter thrown off during cutting, protecting the more precision-sensitive consumables underneath it.
It's part of a Duramax mechanized FineCut/Ohmic consumable stack, which includes a matched nozzle, electrode, and swirl ring rated for the same 30–45A FineCut configuration. Mixing a FineCut shield with non-FineCut nozzle/electrode consumables isn't recommended, since the stack is designed to work together at matched settings.
A standard shield is built for general-purpose cutting without fine-kerf optimization or electronic height sensing. 220948 specifically adds FineCut geometry for detail work and Ohmic compatibility for automated height control — features you'd only need on a mechanized, precision-cutting setup.
Yes, it's sold as a single shield per package.
