SilverPlus® electrodes incorporate a hafnium/silver interface at the point of electrical transfer. The hafnium/silver extracts more heat and has a stronger bond than hafnium/copper.
The result: dramatically longer electrode and nozzle life – increasing productivity and lowering operating costs by reducing the number of consumable sets used and changeouts.
SilverPlus lasts over 2 times longer than standard electrodes
Hypertherm used rigorous life tests to benchmark SilverPlus® electrodes against our standard electrodes. Our 20/20 test involves piercing metal and cutting for 20 seconds with 20% programmed ramp down errors. This means that 20% of the time, we purposely committed errors while cutting, such as running off the plate.
This test protocol is intended to simulate the actual cutting environment. We ran tests using Hypertherm's standard HPR oxygen cutting parameters. These procedures were repeated until the electrode no longer functioned.
