Abstract

A welding machine having an embedded controller with a processor, a network gateway interface device coupled to the embedded controller, an operating program segment stored in a memory of the embedded controller, a gateway communication program segment stored at least partially in the memory of the embedded controller, and a resource sharing program segment stored in the memory of the embedded controller, the resource sharing program segment allocates processing time of the processor between the gateway communication program segment and the operating program segment. The machine may be monitored, controlled, accessed and updated with software over a network from a remote user interface, embodied for example on an Internet browser.
