It is recommended you avoid using welding currents above 160 amps. If welding with currents under 160 amps, follow the precautions below to minimise the risk of interference with your heart device.
Welding safety precautions
Limit welding to currents below 160 amps
Work in a dry area wearing dry gloves and footwear
Maintain at least 60cm (2 feet) between the welding arc and your heart device
Keep welding cables close together and as far from your device as possible. Position the welding unit approximately 1.5 metres (5 feet) from the work area
Connect the earth clamp to the metal as close to the point of welding as possible
Wait a few seconds between attempts when having difficulty starting a weld
Ensure firm footing and adequate space to move freely
Work with someone else who is aware of your condition
Stop welding immediately and move away from the area if you feel lightheaded, dizzy, or believe your ICD has delivered a shock
As welding equipment may temporarily affect your heart device, any decision to use welding equipment should be made in consultation with your cardiologist or device clinic. Protective aprons and vests will not shield your device from electromagnetic interference generated by welding equipment.
