Good to have ya back on IFI... I have a niece that has a pacemaker/defibrillator (has had it since she was 14 years old, now 24) She was not permitted to complete her welding class at the middle school, but she was also banned from motorcycle riding and is not allowed to use a lawn mower for the same reasons as the arc welding. OA welding, and forge welding should be safe, but I would stay away from any welder that uses electric current... Remember your doc is a doc and may not know everything that you do that could be harmful to the ticker keeper in your chest... We'd like to see you around IFI for a good long time to come, when you visit the doc next time be sure to take a list of ALL the activities you enjoy or chores you do and let him read through it...
