While regular welding hoods serve their purpose, they only protect your face and need to be lifted to inspect your work. Welding helmets with auto darkening features adjust the brightness based on the arc’s intensity. This feature allows you to control the darkness without having to pause in between. Some of these welding helmets are equipped with rechargeable lithium batteries. Others use a solar cell that recharges the light generated from welding.

Choose helmets that adjust the shade instantly to match the welder’s arc. This allows for maximum visibility. A wide range of welding helmet shades ensure that it can accommodate various welding conditions. Consider the delay time as well. It determines the amount of time your helmet takes to return to a lighter shade once the welding stops.

​Welding Helmet Shades
A welding helmet shade is essentially the level of darkness or light filtering that the welding lens provides. The unit to measure this level is called DIN (Deutsche Industrie Normen). The darker the shade is, the higher the DIN number is. It’s important to choose the right welding helmet shade level based on the type of welding process you’re using. The wrong shade can cause eye strain and discomfort.

A guide to welding masks

Published date: 28 July

When it comes to welding, safety should always be a top priority. One essential piece of protective gear that every welder should have is a welding mask. These masks shield the wearer’s face and eyes from the intense light, sparks, and potentially harmful fumes generated during the welding process. In this guide to welding masks, we will explore the different types of masks available, highlight their key features, and discuss the hazards they protect against.

Types of Welding Masks

Welding masks come in various types, each with its unique features. The most common types include:

• Passive welding masks: These traditional masks feature a fixed lens with a dark shade that provides protection against bright light, harmful UV and infrared radiation. Passive masks are economical and reliable, but the non-adjustable dark lens requires the welder to lift the mask to see the weld after welding.
• Auto-darkening welding helmets: Auto-darkening masks are a popular choice among welders due to their advanced features. These helmets have a liquid crystal display (LCD) lens that automatically adjusts its shade darkness to the welding arc’s intensity.
• Respiratory welding masks: For welders working in environments with significant fumes and airbourne particles, respiratory welding masks are crucial. These masks not only provide eye and face protection, but also feature built-in respirators or compatibility with separate respiratory systems, to filter out harmful particulates, gases, and vapours.

What hazards do welding masks protect you from?

Welding masks act as a shield against multiple hazards faced during welding operations. These hazards include:

• Arc flash: Welding generates an intense arc flash that emits harmful ultraviolet (UV) and infrared (IR) radiation.
• Sparks and debris: During welding, sparks, molten metal, and debris can be expelled, posing a serious risk to the face and eyes.
• Fumes and particulates: Welding produces hazardous fumes, gases, and fine particulates that can irritate the respiratory system and cause long-term health issues. Respiratory welding masks provide the best protection against these harmful substances.

Key Features of Welding Masks

When selecting a welding mask, there are several key features to consider to ensure optimum comfort and safety. These features include:

• Shade variability: Welding masks with adjustable shade settings allow welders to customise the level of darkness to match the welding process and environment, providing versatility across different welding applications.
• Sensitivity and delay adjustments: Auto-darkening welding masks should have sensitivity and delay controls. Sensitivity adjustments enable the helmet to detect even low-intensity arcs, while delay settings allow for a smooth transition from dark to light after welding.
• Comfort and fit: Opt for a welding mask that offers a secure and comfortable fit, with adjustable headgear and cushioning to reduce strain during extended use. A lightweight design is also desirable, to minimise fatigue.

In conclusion, choosing the right welding mask is crucial when it comes to protecting yourself from potential hazards. As we have seen, there are different types of welding masks available in the market, each with its unique features and benefits. These masks protect you from serious hazards, such as UV radiation and flying debris. Therefore, it is essential to invest in a high-quality welding mask that provides maximum protection and comfort while working. So, gear up and weld away with the right mask, because your safety matters!
