247120 - Miller WeldX Flame Resistant Welding Jacket - 4XL

Advanced Flame Resistance in a Lightweight Package

The Miller WeldX Performance Welding Jacket (Size 4X-Large) represents a significant leap forward in personal protective equipment for industrial welders. Engineered to bridge the gap between heavy leather protection and the comfort of cotton, this jacket utilizes Miller's proprietary WeldX fabric. The front and sleeves are constructed from 7-ounce WeldX material, a high-performance compound that repels sparks, spatter, and molten metal without the bulk associated with traditional cowhide. This specialized fabric is inherently flame-resistant, meaning it will not burn, melt, ignite, or shrink when exposed to the intense heat of the welding arc, providing a reliable safety barrier for professional fabrication environments.

Hybrid Construction for Optimal Comfort

Understanding that heat stress is a major concern for welders, Miller has designed this jacket with a hybrid material approach. While the front provides maximum shielding, the back is made from 9-ounce flame-resistant Navy cotton. This strategic combination significantly reduces the overall weight of the garment compared to full leather alternatives. Furthermore, the jacket features a vented back design which promotes air circulation, allowing body heat to escape and keeping the operator cooler during long shifts. The sleeves are lined for an added layer of thermal protection, ensuring that arms remain safe from radiant heat and stray sparks.

Functional Design and Durability

The Miller WeldX jacket is built for the practical needs of the job site. It features a "Barracuda" style stand-up collar that offers essential coverage for the neck, an area often vulnerable to UV radiation and sparks. The front closure system utilizes a zipper covered by a Velcro storm flap, preventing sparks from entering through the fastening mechanism. For a customized fit, the wrists feature fold-in snaps that reduce loose material near the hands, enhancing safety when working with rotating equipment or feeding wire. The garment is pre-shrunk to maintain its 4X-Large sizing and is fully machine washable, allowing for easy maintenance without degrading its fire-resistant properties. Additionally, being chromium-free, it offers an environmentally friendlier disposal option compared to chrome-tanned leathers.
