Experience the difference crystal-clear vision makes. The 3M Speedglas 100 Welding Helmet boasts an auto-darkening lens with five adjustable shade levels (8-12), ensuring optimal protection for various welding processes like MIG, TIG, and stick. The large viewing area (44mm x 93mm) grants exceptional peripheral vision, minimising head movement and maximising efficiency. Three sensitivity settings allow you to fine-tune the lens response to your specific welding environment, further enhancing control and precision.

But it’s not just about protection. The 3M Speedglas 100 prioritises your comfort too. The adjustable head suspension distributes weight evenly for a balanced, all-day wear, while the sweat-absorbing headband keeps you cool and focused. Plus, the lightweight design reduces neck strain and fatigue, letting you weld longer and stronger.
