What Is a Resistance Weld Monitor
A Resistance Weld Monitor is a professional testing instrument designed for online welding parameter monitoring. It focuses on resistance welding current monitoring, real-time voltage sampling, weld time calculation, and dynamic waveform display. It can record every welding cycle, compare actual values with standard settings, and trigger alarms once parameters go out of tolerance. This ensures each solder joint stays consistent in mass production.
