Benefits of technology
The present invention provides an end panel for a welding power supply housing that solves the problems of previous designs. The end panel has multiple electrical paths through the housing for each terminal post of the welding power supply. The covers on the bezel of the housing are pivotally attached, allowing for easy access to the terminal posts while still protecting them. The bezel can also have a control window and a cover array that allows for air cooling and filtering. The invention also provides a honey-combed opening for cooling flow and filtering particles. Overall, the invention provides better protection and access for the electrical components of the welding-type device while still absorbing stresses from the cable.
Problems solved by technology
This portability means that the welding-type device is exposed to increasingly polluted environments.
Also problematic to the longevity of a welding-type device is the significant amount of particulate pollution in the general area of the welding device when the device is in use.
These pollutants include metal chips and dust generated in preparing work pieces with grinders, hot metal spatter from the welding process, and slag that is chipped from completed welds.
All of these pollutants can adversely affect the operability of the welding-type device and the condition of the terminal posts and receptacles.
Additionally, welding spatter can damage the terminal posts if welding is performed too close to the welding-type device.
As such, these protective devices don't protect the receptacle from debris when the welding-type device is in use.
Additionally, these welding-type devices offer no protection to the terminal posts of the welding-type device.
The terminal posts generally protrude through the housing and are afforded no protection from welding spatter.
As a result, the terminal posts are susceptible to damage from metal spatter associated with metal working processes such as torch cutting and heating, metal grinding, and welding.
These cables can be inadvertently over stressed by an operator during the welding process.
These stresses can concentrate at the terminal post connections and can cause mechanical damage to the electrical system of the welding-type device, the terminal post, or the cable connector.
Due to the environment that these devices are employed in, remote repairs will be inevitable.

Embodiment Construction
[0026] As one skilled in the art will fully appreciate, the hereinafter description of welding devices not only includes welders, but also includes any system that requires high power outputs, such as heating and cutting systems. Therefore, the present invention is equivalently applicable with any device requiring high power output, including welders, plasma cutters, induction heaters, and the like. Reference to welding power, welding-type power, welding device, welder-type device, welder device, or welders generally, includes welding, cutting, or heating power. Description of a welding apparatus illustrates just one embodiment in which the present invention may be implemented. The present invention is equivalently applicable with any power system requiring multiple electrical outputs.
[0027]FIG. 1 shows one such welding-type device 10. Welding device 10 includes a housing 12 which encloses the internal components of the welding device. The welding device 10 includes, a front panel ...

Abstract
A housing of a welding-type device includes a bezel which encloses a plurality of electrical receptacles and a plurality of terminal posts of the welding-type device. The bezel has a first and a second opening corresponding to each terminal post. The plurality of first openings has hinged covers attached to the bezel over the openings. The plurality of second openings is uninterrupted through the bezel and constructed such that the bezel provides strain relief to a welding cable which passes therethrough. The covers are formed such that they allow passage of an electrical cable through the first opening with the cover in a closed position.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a divisional of, and claims priority to, U.S. Ser. No. 10 / 249,909, filed May 16, 2003, the disclosure of which is incorporated herein.BACKGROUND OF THE INVENTION [0002] The present invention relates generally to welding-type devices and, more particularly, to a housing assembly having a plurality of accessory / outlet covers and a number of protected connection paths therethrough. [0003] Welding-type devices generally have a housing which fully encloses the electrical components of the welding-type device. A plurality of electrical outputs is accessible to an operator through the housing of the welding-type device. Preferably, these outputs include terminal posts and receptacles. The terminal posts provide a power signal that is conditioned by the welding-type device to be used for the welding process. The receptacles are preferably electrical receptacles which supply a power signal which has been conditioned to operate...
