TECHNOLOGY

FineCut®

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

What is the Hypertherm 220948 shield used for?

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.

Is the 220948 shield for a hand torch or a mechanized torch?

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.

Which Hypertherm systems is the 220948 shield compatible with?

It's compatible with Powermax45 XP, Powermax65, Powermax85, Powermax105, and Powermax MRT systems, used with the Duramax and Duramax LK/RT mechanized torch series.

What does "Ohmic" sensing mean, and does this shield require it?

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.

What is FineCut®, and when should I use a FineCut® shield instead of a standard one?

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.

What amperage range is this shield rated for?

30–45A, per Hypertherm's own product listing.

What does the shield actually protect in the FineCut/Ohmic configuration?

It shields and helps cool the nozzle from molten spatter thrown off during cutting, protecting the more precision-sensitive consumables underneath it.

What other consumables does the 220948 shield work with?

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.

How is 220948 different from a standard (non-FineCut, non-Ohmic) Powermax shield?

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.

Is this shield sold individually?

Yes, it's sold as a single shield per package.
