Welding technique

The Medtronics pamphlet suggestions are excellent. The most likely problem comes from the magnetic field generated by the high current in the welding leads. If you keep the two current paths (hot and ground) close together the magnetic fields cancel each other. This would be true with both AC or DC welding.
Keep in mind that the effects will disappear as soon as the current stops, so if you feel anything unusual just break the arc. The thing I keep in mind in any activity where there is a potential for interference is to avoid getting into a situation where I could fall into a hazardous place. I try to have someone around when I first try something new and then challenge the situation by getting closer to the source than I will normally work.
I don't weld, but am an electronic engineer and have been exposed to transmitters, generators, motors, etc. I never have had a problem.
I would suggest taking a few weeks to get used to the pacer before starting this sort of activity.

Yes, I still MIG weld with an ICD. I do not use my ICD for any pacing, though.
General rules
Keep the welding tip as far away as possible (they say 2 feet, but I've had it closer..)
Avoid rapid tack welding, if you do pickup EMF from the welder, this might trick the ICD to think you have an arrthymia.
Do not let the cable wrap around you.
Otherwise, I've never had a problem welding post ICD. (Yes, for custom car work as well as just metal work around the house).
Welding !!

Checking with engineering at Medtronic & St. Jude I've been given the precautions of welding with a pacemaker. One caution in common AC arc welding is twisting both leads together which cuts down EMF. Keeping a reasonable distance from the arc is a must. They have given me numereous amperage settting as max like 125 amps with my 1st PM 21 years ago. A few years ago St Jude cleared me for tig doing light low amperage but also cautoned to keep distance from your the welder power unit as it puts out square wave high frequency energy. The square wave output at a high frequency at a high amperage setting could be harmfull.
I was very cautious for years before getting comfortable doing welding electrically as I used gas for some time. To really give you peace of mind I would recomend talking to engineering with both manufacturers giving them the limits of heat you need for your work. Having been in electronics all my life I highly respect the components used inside our pacemakers. Always reminds me of the "Radiation" scare using or servicing microwave ovens when they 1st hit the market. Well, field engineering soon squelched that fear as the danger from microwave radiation would equal the danger of "Someone being Stoned to death by Popcorn".

..................I have looked back on your previous Posting re Crocs and electrical earthing...
You were SO..naive and such a focus for Frank to respond to..
His Crocodile posting was so funny...
Cormac..go up to top right..Search..Punch in ..'Welding there will be a massive fund of stuff there
Be Good
