Welding Factory Current Monitoring

Automatic current monitoring for 12 welding machines with CSV storage for ERP analysis.

PnP IoTs installed a wired Ethernet data-acquisition system at four factory locations. Current measurements from welding machines are collected automatically and stored on a mini PC.

Sensor and RTU installation for welding-machine current acquisition.

Customer Requirement

  • Monitor 12 welding machines with a maximum current of 600 A.
  • Save measured values as CSV files on a mini PC.
  • Provide the stored data to the customer’s ERP company for analysis.

Operational Value

The system replaces manual current checks with continuous digital records. Current patterns can support machine-use analysis, workload comparison, abnormal-condition review, and production reporting.

Sales Message: Existing welding machines can be connected to factory data systems using industrial current sensors, modular RTUs, and standard CSV files.
