Miller's Big Window Elite series of auto-darkening welding helmets feature four independent arc sensors, said to improve out-of-position welding. The unit's lens window is 30% larger than the company's standard helmets. Big Window Elites use Miller's new, replaceable battery/solar assist performance Series lens delivers 3,000 hours operation before batteries need replacing.
