ABSTRACT:
In a magnetic particle testing procedure, a spring loaded prod with contact points prevents arc strikes from occurring between the prod and a part under test. Positive pressure is applied to the prod which engages the contacts before current can flow to the part. Similarly, in removing the prod from the part with the prod power switch depressed, the arcing will occur in the prod assembly and not on the part under test.
