Welding Protection. Every welder knows their work would be impossible without a sturdy helmet. But that helmet also has to be multi-functional and comfortable to wear for long hours. Pyramex Leadhead® auto-darkening welding helmets were created with that in mind. Supported by ultra-comfortable headgear, Pyramex has engineered helmets that will get you closer to the perfect bead. When it comes to your craft, not every job requires the same tools. We also offer passive welding helmets, IR tinted safety glasses, and goggles to help you perform at your best.
