Welding with a pacemaker

The other issues I "could guess" with welders that add trouble spots are plasma and TIG, which both use HF components (arc starter/ stabilizer, etc) and these, along with the arc, generate tremendous interference across the RF spectrum. As a radio amateur (who is no longer very active at all) I cannot imagine living anywhere near a welding shop or even an avid home fabricator. Any welder can wipe out radio reception on many frequencies for a very wide area, on many frequency bands. Regardless of the contention by some that FM radio is less supceptable to RF noise, this generated noise raises the "noise floor" and can reduce weak signal reception. In other words, "it's annoying."
