The Sellstrom WHP4000 Premium Series welding helmet, model SUW-S26400, combines an extra-large viewing area with a Blue Lens Technology auto-darkening filter. Its lightweight construction provides protection for the head and neck, while the design accommodates a cartridge respirator. Intended for professional, full-time welding, it supports work in steel fabrication and erection, shipbuilding, pipeline construction, and refinery construction and maintenance. The wider view helps when welding at difficult angles, and internal controls keep adjustments protected.

• Blue Lens Technology delivers true-colour vision; four arc sensors support clear definition and reduced eye fatigue.
• Digital settings cover shade, sensitivity, delay and welding/grinding selection, with adjustable sensitivity and delay.
• A memory function saves shade, sensitivity and delay settings for different welding tasks.
• Solar and battery power are supported, with automatic power control and a low-battery warning.
• Grind mode includes a grinding warning; the replacement cartridge has a locking mechanism, and the auto-darkening filter and cover plate are easily removed and installed.
• Ratcheting headgear uses a push-and-twist adjustment with locking and release functions for a comfortable fit.
