Welding helmet YATO YT-73921 with auto‑darkening filter, shade 9–13, PC housing, viewing area 4.3×9.8 cm, battery 3V

The Yato YT-73921 welding helmet with auto-darkening filter provides adjustable eye protection for welding tasks. Constructed from durable polycarbonate, the helmet combines a lightweight build with a secure fit. Its viewing window measures 4.3 cm in width and 9.8 cm in height, offering an unobstructed area for monitoring the weld pool. The auto-darkening function activates automatically when an arc is struck, and the unit is powered by a 3V battery for reliable operation during use.

Advantages

The helmet’s polycarbonate shell delivers impact resistance while keeping the overall weight low for extended wear. The auto-darkening filter improves visibility before and after welding by switching from a lighter to a darker state on detection of the welding arc. The compact viewing window balances field of view and protection, and the helmet’s simple design supports quick donning and adjustment.

Suitable for

• Arc welding tasks in workshops and job sites
• Metal fabrication and repair work
• Hobby welding and light professional use
• Situations requiring portable, battery-powered eye protection

Key specifications

• Material: polycarbonate shell
• Viewing window: 4.3 cm (width) x 9.8 cm (height)

How to use

Before starting, ensure the 3V battery is installed and has sufficient charge. Put on the helmet and adjust the headband for a snug but comfortable fit to secure the helmet during movement. Position the viewing window to align with your eye line. When you strike an arc, the auto-darkening filter will activate and darken to protect your eyes; after the weld ends, the filter will return to its lighter state. Inspect the lens and shell for damage before each use and replace any worn or cracked components according to workplace safety practices.

Recommendations

Use the helmet in conjunction with appropriate personal protective equipment, maintain the battery charge to ensure consistent auto-darkening performance, and store the helmet in a dry, cool place when not in use to preserve the polycarbonate shell and optical components.
