Agree 100%. That's how I used to do back in my days of erector engineer before hiring pipefitters, to distinguish them from "pipefitters".
Only one difference: As Shane lives in a first world, developed and rich country, he used TIG wire to carry out the test. As I live in a third world, underdeveloped and poor country, I used a piece of cheap iron wire (the cheapest the better)
