ABSTRACT:
A Computer Controlled Modular Power Supply for Precision Welding (10) that overcomes the problems encountered by previous power supplies is disclosed. A preferred embodiment of the invention includes an enclosure (100) which holds a Computer Control Module (400), a Welding Power Module (500) and an Electrical Power Module (600). These modules are removable, interchangeable and may be used in any combination. The Computer Control Module (400) includes a microprocessor (406) which is programmed using a color LCD display with a touch screen (300) mounted on one side of the enclosure. In a preferred embodiment of the invention, an 80486 chip is used to run a Microsoft.TM. Windows.TM. Operating System and proprietary, user-friendly software developed by Creative Pathways, Inc. of Torrance, Calif. that controls welding operations. The Welding Power Module (500) includes four removable drawers (502) which each contain an individual power unit. The Power Supply is lightweight, portable, and dissipates heat without vents or fans.
