Welding with a pacemaker

The problem will always be legal liability. No manufacturer is going to guarantee that you can't possibly be hurt doing [insert activity here]. Especially since people with pacemakers/defibrillators are already not in the best of health. All it takes is one guy to have his final MI who happened to be welding and everyone gets sued to hell and back. The manufacturer, the hospital, the "rich" doctor... any handy deep pocket. Causation does not equal correlation, but try explaining that to 12 people who see an award as the life insurance lottery...
So it's safest to just say no :realcrazy: in a country with 700K doctors but 1.33M lawyers.

Edited to add: I just saw Prostock Tom's comment. Frankly I'm surprised that they said "up to 175 amps". That sounds entirely too logical.
