287820 - Miller Classic Series Liberty Auto-Darkening Welding Helmet

Product Overview

The Miller Classic Series Welding Helmet in the Liberty graphic (SKU: 287820) represents a significant upgrade for the value-minded welder, integrating Miller's advanced ClearLight™ Lens Technology into an economical package. This helmet is designed for light industrial applications, hobbyists, and DIY projects, offering a versatile range of protection modes including Weld, Cut, and Grind.

Technical Specifications

At the core of this helmet is the ClearLight™ lens, which provides a 1/1/1/2 optical clarity rating. This technology optimizes contrast and clarity in both welding and light states, allowing for a brighter 3.0 light state. The Auto-Darkening Filter (ADF) features a variable shade range of 8-13 for welding, a dedicated cut mode with shades 5-8, and a grind mode shade of 3. The lens switching speed is rated at 1/23,000 of a second, ensuring immediate protection upon arc initiation.

Operational Features

The helmet utilizes two independent arc sensors to detect the welding arc reliably. It is TIG rated down to 5 amps, making it suitable for precision TIG work where stable arc detection is critical. The digital control panel allows for precise adjustments of sensitivity and delay, a significant improvement over analog dials found on comparable entry-level helmets. Power is supplied by a solar-assist system backed by a replaceable CR2450 lithium battery, featuring Manual On/Auto-Off circuitry to conserve battery life.

Construction and Compliance

Constructed from durable nylon, the shell is lightweight at approximately 16 ounces, reducing operator fatigue during extended use. The viewing area measures 5.15 square inches, providing ample visibility of the workpiece. The helmet meets ANSI Z87.1+ and CSA standards, ensuring compliance with rigorous safety requirements. It comes with a ratchet-style headgear for secure fitment and includes a magnifying lens holder for added versatility.
