PC-120A Resistance Weld Monitor
Product features:
- To accurately measure the current value and power-on time, and display
- Set the upper and lower limits of current value and power-on time and monitor them in real time
- The peak value and effective value of current can be measured and monitored
- Just rotate and press the single knob to complete the operation
- Small size, easy to place
- Can communicate with the computer or RS-485, data management
A professional testing instrument designed for online welding parameter monitoring, mainly used for resistance welding current monitoring, real-time voltage sampling, weld time calculation and dynamic waveform display. It can record welding cycles, compare parameters and trigger alarms to ensure consistent quality of batch solder joints.
