Decreasing EMI Interference Produced by TIG Welders

Proper grounding and shielding are important features of your TIG welder setup. Here are 2 drawings showing correct and incorrect layouts.

incorrect TIG electrical layout

The incorrect electrical layout above shows a welder producing radio-frequency-interference (RFI) that affects nearby electrical equipment and is also “transmitted” via telephone-pole power lines to remote electrical equipment.

Correct TIG electrical layout

The correct electrical layout shows a welder grounded to earth via a grounding rod. Nearby electrical equipment is grounded. And power lines are located at least 50 feet (15m) from the welder.

It may also help decrease EMI to run a separate power cable (for AC mains) from your power distribution box (fuse box) to your welder.
