A 5 lens control setting display is configured on an internal portion of the apparatus and located in a field of view of a user when the lens is in a lowered operational position. The externally located combined push button and rotary switch is operable to select and adjust lens control parameters by a user wearing bulky hand protection such as welding gloves or welding mittens. The selection and adjustment level of the lens control parameters can be monitored on the display 0 during the adjustment by a user while the lens is in the lowered operational position.4/6 409 SHADE H SENSITIVITY I 0 412 CUTTING DELAY n L 402 410 406 408 FIG. 4
