Today's electronic welding helmets have made traditional sheet metal masks obsolete. It is an instrument of protection that incorporates maximum technology without sacrificing comfort. How they work, their uses and the best brands, in this article.
The design and technology of Personal Protective Equipment (PPE) has evolved along with the new demands of the workplace. Manufacturers have sought to innovate with the latest advances to guarantee greater safety in any job.
Within this framework, welding helmets have incorporated electronic sealing devices, anatomically designed helmets and other elements to reinforce eye and face protection during welding, while seeking greater freedom of movement and comfort.
We have consulted the information, range of products and comparisons at caretaelectronicaparasoldar.com to answer the main questions when buying this important PPE component.
How does a welding helmet work?
To protect your eyesight, welding helmets incorporate a photosensitive visor that automatically regulates the degree of light.
Thus, when the welding machine is switched off, this shield detects the drop in light level and adapts itself so that the person can see normally, without disturbance or light "traces". When the welding machine is switched on again, the shield quickly darkens.
The purpose of this mechanism is to prevent harmful ultraviolet and infrared radiation, preserving the eye and retina from damage that could be caused by glare.
How is the photosensitive welding mask used?
As mentioned above, this type of mask is used to protect against radiation, sparks and infrared rays when welding. It is therefore important to put it on before switching on the welding machine and only remove it once it has been completely switched off.
It is also important to ensure that it fits properly and securely. Most of today's welding helmets incorporate a gradual adjustment to suit the user's needs.
Electronic welding helmets are lithium battery or solar rechargeable: it is advisable to check the battery level before starting work to ensure that it will be sufficient for the entire process. Solar batteries can be recharged while working, as long as they are exposed to sunlight.
What is the best brand of welding helmet?
Based on the comparisons and information from the website mentioned at the beginning of this article, we conclude that Speedglas, DEKO and Cevik are three of the best brands on the market today.
Speedglas offers anti-glare technology and a delay function of up to 0.1 ms to switch to dark. Preferences can also be adjusted and it has a variable filter with three light sensitivity ranges. The Speedglas helmet ensures adequate eye and face protection and is rated for high impact according to European standards.
What is used in the helmet to protect the eyes and what is the safest helmet?
To enable the welder to see while working but filter out harmful light rays, coloured lenses are used in the helmet. They are usually green and are graduated by numbers up to 12.
According to expert assessments, electronic face shields (also called "photosensitive" or "automatic") are the safest and most efficient. They allow customised adjustment and settings, two hands free and better control of the welding arc, providing safety and freedom of movement.
What should be taken into account when choosing a welding helmet?
- Price-quality ratio
The infinite number of options on the market makes it possible to choose models that offer an optimum level of safety at an affordable price. A safety item is not an object in which it is worth buying the cheapest.
It is advisable that they weigh no more than 500 grams, otherwise they can cause neck and headaches. It is very important to check the weight in the technical specifications of the product.
- Field of vision
It is highly recommended that the visor is of a suitable size so as not to hinder tasks. Certain models incorporate side windows that create peripheral vision.
- Possibility of automatic adjustment of the protective filter
This is a basic feature. Most models incorporate this small device to adjust the brightness of the welding mask at different levels of use and the time it takes to change. The wider the range of shade and the faster the switching speed, the more efficient it will be to use.
