I'm visiting here from RCM.
I've been encouraged to have a defibrillator implanted in my chest. The "school solution" regarding any form of arc welding is "not recommended". However I've seen limited data from a credible source (Journal of the American College of Cardiologists) suggesting that it's not a problem at the light current I use, usually under 200A. (The JACC measurements were done at 900 amps without incident)
I asked the doc today what the downside might be if I were to not heed the "not recommended" advice. He said the defib wouldn't harm or kill me if it fired but I'd feel like I'd been hit by lightning.
He had no trouble persuading me that having one would be a good idea even if I must curtail my welding activities. He asked if welding was a passion with me or something. I said I wouldn't call it a passion, but I certainly would miss being able to do it after spending three decades working on my skills. It'd be a non-trivial loss and kind of a bummer. I'll skip shielding ideas like chainmail, foil shirts, lame, etc., but do feel free to have fun with this. My wife has already suggested cutting the bottom out of a garbage can and putting leather shoulder straps on it. I think she just wants the photos.
I do understand that arrangement of current-carrying cables strongly affects the fields they produce. I'm a retired electrical engineer.
My question for this group: are there any readers here who have ICD's (implanted cardiac devices) and do occasional or routine TIG, MIG or other arc welding, or does anyone here know of people like that?
Respectfully

By the way, Martin Eastburn, the guy said no problem with rifles; he just asked me which shoulder I use so he'd know where to put it.
