See SX1 at E5 and G7 http://www.wallacecompany.com/machine_shop/Hobart_Cyber-TIG/Manual/programmer/hobart_programmer-0051a.png (Short URL) http://alturl.com/2c8xe One of my problems is that I can't watch the meters while welding. It would be nice to have halscope as a voltage and current verses time display. This way I can see what happened after the weld is done, or maybe put a display in my helmet for a realtime display. While I am at it, I could replace the programmer (does current and gas cycle timing) with HAL too. But first, I need to get a good understanding of how the welder works. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Beautiful is writing same markup.
