Auto-darkening welding helmets

The Tweco WeldSkill auto-darkening welding helmet features four sensors for enhanced performance at an affordable price. It can be used in both weld mode and grind mode and will darken when TIG welding even at 5 amps. The helmet has a large viewing area of 3.86 inches by 1.69 inches, weighs 16 ounces, and uses solar power to eliminate the need to change batteries. When switching from light-to-dark, it darkens in 33 microseconds. When switching from dark-to-light, users can select from three switching speeds: short (0.25s to 0.35s), medium (0.35s to 0.50s), and long (0.50s to 0.80). The helmet passes every one of the 49 tests required under the ANSI Z87.1-2010 standards. It has sensitivity and delay knobs on the outside of the helmet shell so that operators can make adjustments while welding. A recessed lens design prevents scratches.
