The voltage and current monitoring of the electric fusion welding machine are inaccurate and need to be manually detected in real time with a real-time multimeter. At present, all electric fusion welding machine manufacturers have made an insulating barrier on the surface of the electrode head without leaving a detection port, which brings inconvenience to measurement and detection. During the electric fusion welding process, continuous monitoring of key parameters such as voltage and current is essential. However, the current method of manually placing the multimeter measuring head on the electrode head for a long time is not only cumbersome, time-consuming and labor-intensive, which seriously affects the construction progress and detection efficiency, but also due to the interference of human factors, such as operator fatigue or unstable placement of the measuring head, it may also lead to inaccurate measurement results, thus failing to provide reliable data support for construction quality control.
