What's kind of neat about the iron powder groupings is the fact they are "drag rods " .Meaning you really don't have to hold an arc like fast freeze .Just strike it like a match and it burns itself .Years ago prior to the advent of sheided arc wire feeds these were used extensively for heavy duty high production in industry . Lawdy back in the day it wasn't uncommon for me to burn at least 50 pounds dailey of 3/16" or 7/32" .I coughed up black chit for 3 months after I joined the navy when I was 19 from that kind of abuse . Number 12 lens with a 2.5 flash google under and I still burned my eyes .---not good at all for you ---
