Welding with a pacemaker

If the pace maker had an on off switch on it, you could turn it off for welding, then turn it back on again when done.

Maybe there is an app for a phone for that.

Don't know, grabbing at straws here.

Could switch over to oxy acetylene gas welding for the small parts you want to weld, like linkage rods and brackets.

No electricity with gas welding.

And yes working on cars, got to be careful to not get zapped from those high energy ignition systems, pulling a plug wire while running and zap Ouch!

Pace makers, got to be happy to be alive in the first place. Everything else is just icing on the cake.
