1, direct sampling, the use of resistance voltage divider arc voltage to the control board.

2, the use of linear optocoupler isolation sampling, the welding voltage divider by a linear optical isolation voltage signal transmission.

3, the use of manual welding machine Hall sensing sampling, the principle of voltage Hall sensor and the Hall current sensor is basically the same, the primary voltage turns on the sensor is not a turn more turns, the edge voltage through the primary series The resistance is converted to the primary current IP, the secondary current Is accurately reflects the primary current, but also reflects the primary voltage value.
