4442.004 - Optrel e684 Silver Welding Helmet for e3000X PAPR System

Technical Precision for Professional Fabrication

The Optrel e684 Welding Helmet (SKU: 4442.004) represents the pinnacle of electro-optical protection for industrial welders. Designed specifically for integration with the Optrel e3000 and e3000X Powered Air Purifying Respirator (PAPR) systems, this helmet assembly includes the necessary air ducting and face seal to ensure positive pressure protection against welding fumes and particulates. The core of the e684 is its adaptive Autopilot technology, which utilizes a sophisticated sensor array to measure the intensity of the welding arc in real-time. This allows the Auto-Darkening Filter (ADF) to automatically adjust the shade level between DIN 5 and DIN 13, ensuring the welder is always protected with the correct opacity regardless of amperage fluctuations or process changes.

Optically, the e684 achieves the highest possible classification according to EN379 standards: 1/1/1/1. This rating certifies top-tier performance in Optical Class, Scattered Light, Homogeneity, and Angular Dependence. The result is an Ultra-HD view of the weld pool without distortion or uneven darkening, even when viewing at acute angles. The lens incorporates a special UV/IR filter that facilitates True Color View, moving away from the traditional green tint to a realistic color spectrum. This enhances the welder's ability to read the weld pool and heat affected zone (HAZ) with greater accuracy. The helmet shell is finished in a heat-reflecting silver coating, which helps reduce the internal temperature of the helmet by reflecting radiant heat from the arc.

Additional technical specifications include a light state of Shade 4, making it suitable for grinding and setup tasks without lifting the hood. The Autopilot feature can be deactivated for manual shade selection if preferred. The sensitivity and delay settings are also adjustable to suit specific welding environments, such as low-amp TIG welding or high-pulse MIG applications. This unit is the helmet assembly only and requires an e3000 or e3000X blower system for full PAPR functionality.
