A Google of "tig welding and pacemakers" brings up a lot of things. A lot
of guys say they weld with pacemakers and no ill effects. Thing is,
pacemakers like hearing aids are being changed and improved all the time.
So, all statements are not an across the board thing. What works for one
person may not for another. And some may be more delicate and sensitive
than others. And everyone doesn't have the same problem or body.

Check with the doctor, Don.
