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.
Claims18
A welding-type apparatus comprising:
- a control panel;
- an indicator connected to the control panel and configured to illuminate to indicate an operating parameter of a welding-type process;
- and
- a cover connected to the control panel and having the indicator disposed therein, the cover designed to enhance illumination of the indicator through the cover when the control panel is subjected to ambient light.
A control panel for a welding-type machine, the control panel comprising:
- a generally planar face;
- an indicator integrally connected to the generally planar face, the indicator designed to illuminate upon a given operating condition of a welding-type machine and emit light at a given wavelength;
- and
- a contrast enhancement filter disposed at a light-emitting end of the indicator and configured to filter light impinged thereon at wavelengths other than the given wavelength.
A welding-type machine comprising:
- means for providing a welding-type output;
- means for visually indicating operating status of the providing means;
- and
- means for enhancing illumination of the visual indicating means relative to intensity of ambient light incident on the visual indicating means.
