Machine grounding and High Frequency Interference Protection
This welder must be grounded to earth
The high frequency generator being similar to a radio transmitter may cause interference
to radio, TV and other electronic equipment. These problems may be the result of
radiated interference. Proper grounding methods can reduce or eliminate this.
Radiated interference can develop in the following ways
1. Direct interference from welder power source
2. Direct interference from the welding leads
3. Direct interference radiated from feedback into power lines
4. Interference from re-radiation by un-grounded metallic objects
