K4931-M - Lincoln Electric XVI Series Hybrid FR Cotton Welding Jacket, Medium

Technical Overview of the Lincoln XVI Series FR Welding Jacket

The Lincoln Electric XVI Series Industrial FR Welding Jacket (SKU: K4931-M) is a technically advanced personal protective garment designed to address the specific ergonomic and safety challenges faced by professional welders. Unlike traditional uniform-weight jackets, the XVI Series employs a strategic hybrid fabric construction. The front panels and sleeves—areas subject to the highest exposure of radiant heat and molten spatter—are fabricated from heavy-duty 16 oz. Flame Retardant (FR) grey fabric. This high-density material provides a robust barrier against thermal hazards that would typically degrade lighter garments. Conversely, the back panel and shoulders are constructed from 9 oz. black FR cotton, significantly reducing the overall weight of the jacket and promoting airflow to mitigate heat stress during prolonged operation.

A critical failure point in many welding jackets is the front closure, where sparks can bypass buttons. Lincoln Electric addresses this with a multi-layer closure system that integrates three layers of fabric and a Velcro storm flap, effectively sealing the front of the jacket against spark intrusion. The garment also features an innovative cushioned collar and cuff design. Lined with moisture-absorbing foam and fleece, these contact points eliminate the chafing and pressure often associated with stiff FR collars, while adjustable snaps ensure a secure fit compatible with welding gloves. The K4931-M is designed for longevity and ease of maintenance; the all-FR fabric construction is machine washable, retaining its protective properties for up to 100 home washings or 50 commercial wash cycles, offering a hygienic and cost-effective alternative to non-washable leather apparel.
