WM-200A Industry 4.0 Ready Networked Weld Monitor

March 18, 2023
Amada Weld Tech's high-speed IIoT resistance weld monitor closely monitors the welding process while capturing critical data.

The IIoT-ready WM-200A Networked Resistance Weld Monitor enhances resistance weld monitoring capability by simplifying data capture, storage, and analysis on a networked platform. It monitors all aspects of the resistance welding process providing visual and statistical feedback during R&D as well as production environments. High-resolution data capture is critical for AI and ML algorithms. It also provides immediate feedback to the weld station by monitoring key aspects of the process and sending good/no good information to the process controller instantaneously during production.


Whether connected to a standalone resistance welding station or implemented in an automated system, the WM-200A enables users to collect large amounts of high-resolution process data to be used for manufacturing traceability, statistical data analysis, equipment efficiency, and health. Data can be stored on an on-premise or cloud-based server and viewed or downloaded from a remote location using the remote graphic user interface.


The weld monitor inputs include current, voltage, displacement, and force. The monitor features a user interface for easy programming and quick access to view waveforms and numeric data. Configurable monitoring screens enable custom viewing. The WM-200A offers high-resolution data capture (up to 200 kHz sample rate) and can simultaneously monitor eight different inputs and up to four distinct windowed process limits per primary channel.


It communicates with direct I/O and TCP/IP communication protocols; optionally, configure with an EtherNet/IP field bus to allow automated systems to communicate easily over a single communications cable. Stored data is accessible by third-party software suites for analysis for SPC, OEE, and equipment health.
