Abstract
A welding-type apparatus has a control panel with enhanced viewability. The control panel may include LEDs, backlit LCDs, and other light-emitting indicators whose viewability by a user is enhanced when the control panel is subjected to relatively intense ambient light, such as direct sunlight. The control panel includes light reflecting, light refracting, light filtering, and/or light absorbing components to enhance the intensity of the light emitted by the light-emitting indicators relative to ambient light incident thereon.
