OVERVIEW

Maximize Your Powermax System with Genuine Hypertherm Consumables

Upgrade your mechanized cutting setup with the Hypertherm 220948 Ohmic Shield, specifically engineered for FineCut applications. This component is a vital part of the consumable set for Duramax mechanized torches used with Powermax 65, Powermax 85, and Powermax 105 plasma systems. The FineCut process is renowned in the industry for delivering "laser-like" cut quality on thin metals, offering a cost-effective alternative to more expensive cutting methods without sacrificing precision.

The Role of the Ohmic Shield

In automated plasma cutting, the shield serves a dual purpose: it protects the inner nozzle from molten spatter and directs the shield gas flow to stabilize the arc. The 220948 goes a step further by providing ohmic contact. This electrical connectivity allows your CNC table's height controller to sense the workpiece surface by touching it with the shield tip before the arc fires. This "ohmic touch" sets the perfect pierce height every time, which is crucial for preserving nozzle life and achieving square cut edges. Without a functioning ohmic shield, automated systems may struggle to find the plate, leading to pierce errors or collisions.

FineCut Technology Explained

Hypertherm's FineCut consumables are designed to produce a denser plasma arc. This 220948 shield works in conjunction with specific FineCut nozzles and swirl rings to constrict the plasma stream, resulting in a significantly narrower kerf width. This is particularly beneficial when cutting intricate shapes, holes with small diameters, or fine contours in mild steel and stainless steel. Operating within the 30-45 Amp range, it provides excellent control on materials typically up to 3/16 inch (4 mm) thick, minimizing the heat-affected zone (HAZ).

Genuine Quality Assurance

Using aftermarket or "knock-off" consumables can lead to inconsistent arc starting, poor cut angularity, and even damage to the torch head. The Hypertherm 220948 is manufactured with precision tolerances to ensure perfect alignment within the Duramax torch. This alignment is critical for maintaining the gas flow dynamics required for FineCut performance. Invest in genuine Hypertherm parts to ensure your equipment delivers the reliability and cut quality your projects demand.

FAQ

The 220948 shield is compatible with Hypertherm Powermax 65, 85, and 105 systems equipped with a Duramax mechanized torch.

An ohmic shield, like the 220948, is electrically conductive and allows the torch height controller (THC) to sense the workpiece surface via electrical contact, ensuring precise initial height positioning.

This shield is designed for FineCut applications operating between 30 Amps and 45 Amps.

No, this specific shield (220948) is designed for mechanized (machine) cutting. For hand cutting FineCut applications, you would typically use a deflector or a different shield designed for drag cutting.

FineCut is best suited for thin-gauge mild steel and stainless steel, typically providing superior cut quality on materials up to 3/16 inch thick.

Yes, the 220948 shield must be used with the corresponding FineCut nozzle, electrode, swirl ring, and retaining cap to function correctly.

Replace the shield if the orifice becomes clogged with spatter, if the face is pitted or damaged, or if the ohmic electrical contact becomes unreliable.
