TP Tools Auto-Darkening Welding Helmets have a filter lens which immediately darkens to the shade when an arc is detected. There's no need to flip the lens or bob your head. Just strike the arc, the rest is automatic. These helmets provide protection against IR and UV radiation when viewing through the filter. In event of a solar failure, the lens will remain dark to provide eye protection. Helmets feature adjustable ratchet-type head gear suspension with soft sweatbands, and auto 15-30-minute shutoff.
The eye protection you need at an affordable price. Variable-shade lens adjusts from 9-13. Recessed lens design puts lens closer to your eyes where you need it -- the result is a clearer, unobstructed view with larger peripheral vision. 2 photo sensors for arc detection and solar-powered lens - no batteries to change, no tuning - just start welding, and helmet does the rest. UV/IR protection up to shade 16. 1.38" x 3.8" lens size.
AUTO-DARKENING TERMS:
Switching Speed - The time it takes an auto-dark lens to change from light to dark.
Light State - The shade of the auto-dark lens when sitting idle. The lower the shade, the greater visibility you have when viewing through lens, prior to striking an arc. When welding in a dark, low-light area, this is extremely important.
Dark State - The shade of the auto-dark lens when activated.
Dark to Clear Delay - The time it takes for the auto-dark lens to go from the dark state to clear state. Useful when tack welding repetitively.
Sensitivity Adjustment - for fine-tuning the auto-dark lens for ambient light or arc intensity.
