Hi group



I never thought much about it before today, but I found out ground loop can be mighty painful!



I have done a fair share amount of TIG welding over the years. I have done a fair amount of milling 304 Stainless steel as well. No matter how careful with Stainless milling, once in a while you end up getting a microscopic splinter. I have pretty good close up vision and sometimes have a hard time even with magnifier.



I never did a little milled, do a little TIGing, mill, TIG etc. many times before.



Well, today a few times I had a microscopic splinter in my left wire feed hand that managed to touch the welding rod with my elbow resting on the aluminium welding table: "WOW"! I guess the splinter however small was more connected to my biological  saline solution.



That minute amount of electron flow really got my attention. To add insult to injury, I couldn't find the darn splinter one time by sight. It took three iterations of using ground loop to find it!



As far as ground loops go: I'll take a little static listening to the radio anytime over TIG splinters
