Jack, I've considered using a 28 V, 100 A Leece-Neville alternator for welding (TIG). It is gathering dust on my M561. Unless someone wants to buy the 561. ;-) Of course, one needs to cobble up a good regulator for it. ;-) Dave > ------------------------------------------------------------------------------ > Infragistics Professional > Build stunning WinForms apps today! > Reboot your WinForms applications with our WinForms controls. > Build a bridge from your legacy apps to the future. > http://pubads.g.doubleclick.net/gampad/clk?id=153845071&iu=/4140/ostg.clktrk > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
