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.
Claims20
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 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.
