Miller Enterprises 770660 ArcArmor Auto Darkening Welding Lens Shade 8

Miller ArcArmor 770660 Welding Lens

The Miller ArcArmor 770660 is a fixed-shade auto-darkening welding lens rated at Shade 8. It fits helmets that accept 2 by 4 inch plates and uses two arc sensors with auto-on or auto-off circuitry powered by solar cells. The gray lens meets ANSI Z87 and CSA Z94.3 standards.

For Single-Shade Stick And MIG Work

This lens suits welders who stay on one process and amperage range where a constant Shade 8 is appropriate. It is not for jobs that require variable shade adjustment or grind mode. Buyers needing multiple shade levels or a wider viewing area should look at variable-shade alternatives.

Fixed Shade 8 With Two Arc Sensors

The lens handles stick and MIG applications that fall within the Shade 8 protection window. Solar power removes battery changes but relies on ambient arc light to operate. It runs out when the process demands a darker or lighter fixed shade or when a larger plate format is required.
