Molybdenum (Moly) Electrodes:
– Moly Electrodes have a higher melting temperature which means you will erode more of the broken tool and less of the electrode making Moly less expensive to use than other materials.
Graphite Electrodes :
– When removing large bolts .750″ to 19 mm and up use Graphite Electrodes for optimum performance and value. Graphite Electrodes only work on metal disintegrators with 20KVA or DC power supply.
