Hypertherm is introducing SilverPlus electrodes for its HyPerformance HPR400XD plasma cutting systems. Thorough laboratory testing shows SilverPlus electrodes last 50 per cent longer than standard copper electrodes in most cutting applications. Instead of replacing the electrode at a pit depth of 0.040 of an inch as recommended with standard copper electrodes, SilverPlus electrodes are designed to last to a pit depth of at least 0.080 of an inch. In addition, the electrode delivers a very consistent range 4 and 5 cut quality throughout its life. This allows owners to lower their operating cost with no impact on cut quality or speed.
