The Hobart inventor series helmets offer a 9.3 square-inch viewing screen, four arc sensors, and grind mode. These are cost-friendly helmets with analog controls, offering variable shades of 9-13 and a shade 3 light state, along with sensitivity and delay controls. The inventor series helmets only weigh 19.7 ounces so you never need to worry about neck strain from a heavy helmet. The auto darkening filter has an "auto-on/off" power control so the lens is triggered at the strike of an arc. These helmets are cheater lens capable, accepting a standard 2 x 4 inch magnifying lens.
