Abstract: A gas tungsten arc welding system includes a welding power source including a controller comprising a memory storing a plurality of parameters that at least partially define a welding waveform. The welding waveform includes a high frequency stage, an AC arc initiation stage following the high frequency stage wherein the AC arc initiation stage comprises a plurality of AC current pulses that decrease in amplitude during a slope duration, and an AC sequencing stage following the AC arc initiation stage. The system further includes a user input in communication with the controller and configured to receive a manual activation of an increased energy AC arc initiation mode. The controller is configured to increase energy of the AC arc initiation stage, when the increased energy AC arc initiation mode is activated, by at least lengthening the slope duration of the AC arc initiation stage.

Abstract: Various distributed client side printing methods and systems are described. In at least some embodiments, printer control and the job handling functions are bifurcated or separated by allowing jobs, drivers, settings and the like to be controlled by the print server or some other entity, while allowing clients to communicate jobs directly to a printer. The various embodiments can improve server performance by performing rendering and maintaining rendered data on the client side, and not communicating the rendered data to the server, while at the same time, allowing print servers to control the printer.
