Dear Mr. Burton,
Thank you for contacting Medtronic Patient Services. If you do choose to weld after consulting with your physician, follow these welding safety precautions to minimize the risk of interfering with your implanted heart device:
• Limit welding to currents less than 160 amps
• Work in a dry area with dry gloves and shoes.
• Maintain a 2-foot (60 centimeter) distance between the welding arc and heart device.
• Keep the welding cables close together and as far away as possible from the patient’s heart device.
• Place the welding unit approximately 5 feet from the work area.
• Connect the ground clamp to the metal as close to the point of welding as possible.
• Arrange the work so the handle and rod will not contact the metal being welded if they are accidentally dropped.
• Wait several seconds between attempts when having difficulty starting a weld.
• Work in an area that offers firm footing and plenty of room for movement Work with an informed person who understands these suggestions.
• Immediately stop welding and step away from the area if the patient start feeling lightheaded or dizzy or if the patient believes their implantable defibrillator has delivered a shock
Welding above 160 amps is not recommended, maintain at least 5 feet from the welding area and components for welders up to 400 amps.
NOTE: There is no apron or vest that will effectively shield the Medtronic heart devices from the electromagnetic fields generated by the welding equipment.
Welding precaution guidelines support the following types of welding machines:
• EDM - Electromagnetic Discharge Machine
• GMAW - Gas Metal Arc Welding types:
• MIG - Metal Inert Gas welding
• MAG - Metal Active Gas welding
• SMAW or MMA - Shielded Metal Arc Welding or Stick Welding or Manual Metal Arc welding
• GTAW or TIG – Gas Tungsten Arc
• Welding or Tungsten Inert Gas
• Helium arc
• Plasma cutters
• Gouging
• Alternating Current (AC) or Direct Current (DC)
