Welding helmet Deca WM 31TC — passive protective welding helmet model WM 31TC

Deca WM 31TC is a passive protective welding helmet designed to provide essential head and face protection during a variety of welding operations. The helmet offers full-face coverage and a fixed protective viewing window that shields the operator from sparks, spatter and harmful infrared and ultraviolet radiation commonly produced by welding arcs. Constructed for workshop and on-site use, this model delivers a straightforward, reliable barrier between the welder and welding hazards while maintaining a simple, durable design suitable for frequent use.

Advantages

The helmet’s passive viewing window requires no electronics or batteries, ensuring continuous protection without maintenance for the lens. Its full-face shell covers the forehead, eyes, nose and chin to reduce exposure to spatter and flying debris. The construction emphasizes durability and ease of use, with a stable fit that helps maintain the viewing position throughout typical welding tasks. The fixed filter provides consistent optical performance and eliminates the potential failure modes associated with auto-darkening systems.

Suitable for

• Basic welding tasks in workshops and small fabrication shops
• Construction site welding and repair work
• Metal fabrication and maintenance operations where passive protection is acceptable
• Training environments and educational welding demonstrations

Key specifications

• Type: Passive welding helmet with fixed viewing window
• Coverage: Full-face protection including forehead and chin
• Protection: Shields against sparks, spatter, and infrared/ultraviolet radiation
• Lens: Fixed protective filter providing constant shade level
• Design: Durable shell suitable for workshop and on-site use

How to use

Place the helmet over the head and adjust the headband to achieve a secure and comfortable fit that keeps the viewing window aligned with the eyes. Before starting any welding operation, inspect the lens and shell for cracks, deep scratches or other damage that could reduce protection or visibility. Use the helmet consistently during arc welding, cutting or grinding activities that produce sparks, spatter, or harmful radiation. Replace the helmet if deformation or damage is detected that compromises protective coverage or fit.

Usage recommendations

Regularly check the viewing window for contamination and clean with a soft, lint-free cloth and mild detergent; avoid solvents that can damage the lens. Combine the helmet with appropriate respiratory protection, gloves and protective clothing when working in environments with fumes, hot spatter or moving machinery. Store the helmet in a dry place away from direct sunlight when not in use to preserve shell and lens condition.
