RS PRO Welding Helmet

From the trusted RS PRO brand, this high-quality welding helmet is suitable for professional applications, such as MIG welding and TIG welding. The welding mask has a lens size of 91mm x 42mm, allowing a good field of visibility. It also attaches with an adjustable strap for comfort and security.

This auto-darkening welding helmet switches from light to dark state automatically when the welding activity starts. This is essential for protecting your eyes at work and conforming to health and safety standards. The light state is DIN 4 while the dark state is a variable shade that is adjustable from DIN 9 to DIN 13 using an external knob. The welding maks response time from light to dark state is 0.04 milliseconds and it returns from dark to clear state in 0.03 seconds to 0.04 seconds.

Power is supplied by solar cells, and the two built-in lithium batteries offer power back-up for longer service life and no need for replacement batteries. This convenient solar power system allows for a long work life with minimal maintenance requirements.

Auto-darkening welding helmets, or welding hoods, are essential personal protection equipment wherever arc welding takes place. They have advantages over welding masks that simply have static polarized viewing lenses, in that you can see as normal when not welding without having to adjust your mask. The viewing lens only darkens in response to the light given off from arc welding. In many countries, an auto-darkening welding mask is an industry safety requirement wherever welding equipment is used, and they are regarded as a standard piece of safety equipment for welders.

The helmet has advantages over goggles in that they also protect the face and neck from flash sparks, and can even serve as face protection PPE when grinding.
