Automatic Changing Light Welding Mask with DIN4 Lampshade and Wide 122.5x35mm View

This automatic welding mask, or protective headwear, is engineered for arc welding applications where consistent eye protection is paramount. It integrates an automatic darkening filter that activates upon detection of an arc, powered by two dedicated sensors. The core benefit is immediate protection, with a switch time of just 3/10000ths of a second, shielding your eyes from intense light. It provides a substantial effective viewing area measuring 122.5 by 35 millimetres, offering a clear field of vision while you work. With a UV protection grade of DIN16 and an operating temperature range from -5 to +55 degrees Celsius, it is built for practical use in various workshop environments. The entire goggle unit is designed to be lightweight at 195 grams, reducing neck strain during extended wear.

Features and Construction

This welding mask's functionality centres on its responsive optical system and robust build. The construction prioritises reliable performance for welding tasks, using materials chosen for their practical application in protective gear.

Material and Build

The frame of the protective headwear is made from PP, or polypropylene. This material contributes to the product's overall light weight of 195 grams, making it less cumbersome for the user. The black colour provides a neutral, professional appearance. The build incorporates the optical assembly, including the DIN4 grade lampshade, which houses the automatic darkening lens. The lens itself offers a darkening range, operating between DIN5 to DIN9 or DIN9 to DIN13, adapting to different welding intensities.

Size and Practical Fit

The key dimensional feature is the effective viewing area of the lens, which is 122.5 millimetres wide by 35 millimetres high. This rectangular viewport provides a practical work zone for monitoring the weld pool and surrounding area. The physical package size of the product is 210 by 100 by 90 millimetres, indicating its compact form for storage or transport. The 195-gram weight is a concrete figure that informs you of its light physical load, which is a practical consideration for comfort during long sessions.

Uses and Placement

This product is specifically designed for scenarios involving arc welding, where high-intensity light and UV radiation are present. Its placement is as essential personal protective equipment (PPE) for anyone performing or observing such work.

Event or Professional Use

In professional fabrication, manufacturing, or construction settings, this automatic mask offers a hands-free safety advantage. The two arc welding sensors ensure detection from multiple angles, which is useful in dynamic work environments. The stepless sensitivity adjustment allows a welder to fine-tune the trigger point to match their specific equipment and ambient light conditions, preventing accidental darkening or failure to darken. The adjustable delay time, from 0.1 to 1.0 seconds, lets the lens remain dark for a set period after the arc stops, protecting from lingering brightness.

Everyday Home Use

For DIY enthusiasts, hobbyists, or individuals undertaking home improvement projects involving metalwork, this mask provides a high level of protection in a ready-to-use format. The fact that it includes the required CR2450 battery means it is operational straight from the package. Its ability to function in an 'outdoor' mode and across a broad temperature range makes it suitable for use in garages, sheds, or outdoor workspaces that may not have controlled climates.

Benefits and Buying Value

The value of this welding mask lies in its automated protection, practical specifications, and straightforward operation. It is a tool that serves a clear, safety-critical function based on its stated technical data.

Reuse and Low Maintenance

The product is designed for repeated use. Its power is supplied by a standard CR2450 button cell battery, which is a user-replaceable component, supporting long-term use. The PP construction suggests a degree of impact resistance and durability inherent to the material, though the source does not specify a lifespan. Maintenance is minimal, primarily involving battery replacement and lens cleaning to preserve optical clarity.

Why Choose This Product

You would choose this automatic welding mask for its concrete, source-supported features: the automatic darkening triggered by two sensors, the wide 122.5x35mm viewing area, the DIN16 UV protection rating, and its light 195g weight. It compares generically to basic fixed-shade masks by offering automated, adaptable protection that increases convenience and potentially reduces eye fatigue. The included battery and adjustable sensitivity and delay settings offer a complete, configurable package for the user focused on practical welding safety.
