Weldclass PROMAX 850R Flip-Up PAPR Welding Helmet with R50 Powered Air Respirator
The PROMAX 850R combines a next-generation Weldclass auto-darkening welding helmet with the PROMAX R50 battery powered air purifying respirator (PAPR). Filtered air is fed into the helmet, keeping you cool and protected from welding fume particles, while the huge 95cm2 landscape lens with V1 rated optics gives a crisp, true-colour view of the weld pool. The 850R adds a flip-up welding lens with a large clear grinding visor for seamless switching between welding and grinding, shade 5 side windows for wide peripheral vision, and a bonus second battery for uninterrupted performance on longer shifts. It is a complete fume protection system for welders who spend long shifts on MIG, flux-cored, stick or TIG work and need respiratory protection without the hassle of a separate mask.
