Product Detail

Plasma cutting shield is a key accessory for ensuring cutting performance and extending the torch's lifespan. The 420291 plasma shield is specifically designed for cutting non-ferrous metals such as aluminum and stainless steel at 40A current, serving as a high-cost-effective alternative consumable for XPR series torches.

Core Advantages

1. 40A Non-Ferrous Metal Cutting Special Optimization

This 420291 shield is optimized for gas flow channels in 40A non-ferrous metal cutting scenarios. It forms a stable gas protection barrier, resulting in clean cut surfaces without slag buildup when cutting aluminum and stainless steel. Minimal post-cutting grinding is required, making it particularly suitable for sheet metal processing, decorative engineering, and other applications with high surface finish requirements.

2. Durable and Impact-Resistant, Protecting the Torch

With thick wear-resistant material and an extended skirt design, it effectively blocks flying molten slag and debris from cutting. This prevents damage to the internal core components of the torch, extending its service life by 30% compared to ordinary shields and reducing torch maintenance costs.

3. Precision Machining, Strong Adaptability

Strictly CNC machined according to OEM standards, with dimensional errors controlled within ±0.02mm. When fitted onto XPR torches, it ensures a perfect seal, stable gas output, unshifted arc, consistent cutting performance throughout, and easy handling even for beginners.

Recommended Consumables for 40A Cutting
