I'm not qualified to give scientific research here - but in laymans terms can we assume that if you don't wrap the leads around you & try to keep the torch away from the immediate area of the pacemaker the current involved will be relatively small - so the thickness of the mesh does not need to...

Joe; If shop around at the Medieval Custom costume makers, try to find someone that will make you a "light weight" chain mail vest, but have it made from copper. But the most important thing is to make sure you keep a good ground attached to it. By doing this you are creating a faraday ca...

Joe Buddy, Take a look at Mu-metal, it is a range of nickel-iron alloys that are notable for their high magnetic permeability, composed of approximately 77% nickel, 16% iron, 5% copper and 2% chromium or molybdenum.[1][2] The high permeability makes mu-metal useful for shielding against static or l...

I talked to my neighbor that works at Honeywell and he works on equipment that requires EMI protective suits. He is going to see what is available that might work for my situation. I am an IBEW member but the guys that work the High voltage refer to us as "Narrow Backs" or "Low Voltag...

Some great ideas here. I am trying to set up a test with one of my neighbors to see how good the mesh shielding works. The butcher chain mail looks promising. I have 2 neighbors that work for Honeywell and know how to set up the test. Thanks for the input.

I have been reading about the Faraday cage. There are silver plated fabrics that are used for this purpose but your idea is one I had not thought of. I have some experience with EMI shielding from Cape Canaveral and in Nuclear power. Way too expensive. I have used a wire mesh like you have described...

I have checked and I have concluded that I am not willing to take a chance on damaging the pacemaker. I am trying to find shielding material cheaper than $1,000 a square meter. And no I am not kidding.

I've had a pacemaker implant and I'm not sure about using a Mig welder now. I have been looking for an EMI shielding jacket to wear when I am welding but there doesn't seem to be one available. I weld mainly on sheet metal for classic cars and really need to continue. Any info on shielding?

I certified to weld Iso Phase a few years ago and had problems with porosity. One of the other guys testing had very little porosity and I can't figure what was causing it. I almost failed the test. We were using the same machine (Cobra Matic) and the same settings. I had welded Iso Phase befor on a...
