| Abstract: | The high-frequence oscillator used in TIG welding is a serious interference source to the nearby electronic circuits.The paper investigates the factors affecting high-frequency interference,of which include the high-frequency interference,the length of welding cable and power line,the output resistance of signal source,the type,length and orientation of signal line,the shielding and grounding of high-frequency oscillator,power line and signal line.Based on the results,the measures to prevent high-frequency interference are put forward. |
