Cordless Drill-Drivers, Cordless Impact Drivers

Opinions on using (not using) cordless impact tools i.e. 18V-20V cordless drill-Drivers (Hammer Drills) and Impact Drivers (1/4" drive and 1/2" drive)

Not supposed to be a probem if keeping at least 6" from PM.

I see on your bio you use, or will use a MIG.  Now that could be a problem.  I've read so much pro and con about these, as I have one as well, altho haven't used it yet with my PM.  Of course it's kinda hard to keep it 6" or even a foot from your PM.  That should be discussed with your cardio.

I agree, especially with Stich welding..I'm seriosly considering very frustrated by this!

Not a problem. I use them every day, along with any other tools found in a serious woodworking shop.

That's reassuring. I have some shielding patches on order. Hoping my appt with the PM Dr will also agree, I seem to remember him telling me not to sell it just yet.

TeeJs1 -- didn't know shields were even available.   A quick Goggle on them shows what looks like a really thick small disc.  And not cheap either.  Would be real interested in what your PM Doc has to say.

Other than possible mechanical protection for contact sports, these are snake-oil (and that's being unfair to snakes).  They aren't going to stop any EMI and won't do anything to reduce magnetic fields. Save your money.

Shields and power tools

There are two problems here.

Electromagnetic radiation (EMR) and magnetic fields.

We live in a sea of EMR from mobile phones to TV signals. There are anti-mobile mast people around, but probably the same ones as use their phone to complain.

To stop EMR getting to you, you need some serious but impractical measures like a Faraday cage suit.

I would take medical advice on working closely with arc welders, but I'm sure the UV is more of a hazard.

The other hazard of course is a strong magnetic field as this could interact with the pacemaker.

The PM will be well shielded from day-to-day fields, but in the Medtronic device I have and probably others, it has a magnetically operated switch to perform the so-called magnet test when you see the physiologists for a full checkup.

I use a lot of tools cordless etc. and some do have increasingly powerful magnets in them where DC motors are concerned. A hard drive disk unit has incredibly strong magnets in them which I harvest as tool hangers.

Rare earth magnets do pose a problem if they get near the PM. I've just tried one at 6" and no effect. I wouldn't try it at 1".

The PM will have something in it called a reed switch or maybe a Hall effect sensor. The reed switch only operates as long as the magnetic field is there, it's momentary.

The Hall device can be latching or momentary.

The PM man said it was momentary.

I also do a lot of electrics and electronics. Sooner or later, you are going to get a belt of 240-V AC. I've used up my nine lives, but nothing affected the PM. As a rule, though I never work with two hands on something if it’s live. The shock you normally feel is you charging up like a capacitor. Earthing yourself with the other hand is a different, sometimes fatal matter.

On the whole PMs are robust devices that let you just get on with life and it's up to you to assess the risks and take precautions before you start. Have a helper handy as well to call the emergency services.

Now we are talking DATEs. I was using Those in the late 60's early 70's.

My past is in electronics and am Tube , like you, the one hand rile ...'Rules'.

I really appreciate all of the input. I have an appt today with the PM folks...Hoping for the best.

You all have an absolutely wonderful day..

Sometimes a device must be tuned a few times before it is right. My cardiologist said it is like fine tuning a car.
