Tweco auto-darkening welding helmet features four sensors
The Tweco auto-darkening welding helmet features four sensors for enhanced performance. 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 viewing area of 3.86” x 1.69”, weighs 16 oz., and uses solar power to eliminate the need to change batteries.
When switching from light-to-dark, this Tweco helmet darkens in 33 microseconds, or 1/30,000th of a second, one of the fastest reaction times available (by way of comparison, a human eye blink takes 3/10th to 4/10th of a second). 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). Operators in high amperage applications prefer a longer transition time, giving the red-hot weld puddle a chance to cool.
Designed to combine safety, strength, flexibility and comfort, the Tweco WeldSkill four-sensor helmet passes every one of the 49 tests required under the ANSI Z87.1-2010 standards. This includes the ability to retain its auto-darkening performance even after high impact by a steel ball.
Tweco placed the sensitivity and delay knobs on the outside of the helmet shell so that operators can make adjustments while welding. When setting the helmet down, a recessed lens design prevents the faceplate from touching the table, protecting it from scratches.
