We have loads of machines with pacemaker warning signs at work from welders , lathes to stuff that use linear magnetic drives . We had an outside specialist firm measure every piece of equipment for EMF and the worst was a SDS drill but even that was way below levels that would affect anything . We left the signs as a precaution but our big spot welder , industrial MIG , Miller TIG welder anything with a motor and magnetic linear drives were all a tiny fraction of the pacemaker level .
