Spec:
feature
1.Output control
Multiple output modes: Supports constant current, voltage or power output, and can select the most appropriate mode according to different welding workpieces and materials.
AVIO automatic voltage/current optimization: Through sophisticated sensing and control technology, the system can automatically adjust the output voltage and current to ensure welding quality and reduce the operator's setting time.
2.Welding process monitoring
Pre-welding inspection: Before welding begins, the system will conduct a series of inspections to ensure that the equipment and workpiece are in optimal condition to avoid defective products.
Long welding time: The maximum welding time can reach 3 seconds, meeting various welding needs.
Real-time waveform display: Equipped with a large-size LCD screen, it can display the voltage and current waveforms during the welding process in real time, making it convenient for users to monitor the welding quality.
Multi-parameter monitoring: The system can monitor multiple welding parameters at the same time, such as welding voltage, current, time, power, etc., and store the data for subsequent analysis and optimization.
Welding waveform memory: The system has a built-in memory function that can store multiple sets of welding waveforms, making it convenient for users to compare and refer to, and help quickly find the best welding parameters.
Content:
The NRW-IN4200 inverter resistance welding model was designed to support precision weld of leads to terminal boards and leads to leads on electronic components. The built-in monitor eliminates the need for an external welding monitor. This model responds to changes during welding in real time due to the fast monitor feedback which improves the bond quality. The high stability welding current generated by the power supply is ideal for resistance welding of precision electronic parts.
