Product Description

Fully digital and WiFi enabled, the ALX III RS weld monitoring and data-logging system, uses the very latest technologies. This allows it to use wireless technology for both network connectivity and for use with TVC Wireless Sensors. 

Single or Dual Rack System (RS)

The ALX III RS unit is available as single or dual channel system. The system can be used on all popular arc welding processes and is protected against damage from the high frequency/high voltage start systems used on many TIG welding power sources.

Rugged, hard-working and designed to withstand tough working environment and conditions, it is equally at home monitoring welding procedures, qualifying welders or in a laboratory situation where precision welding of fine components and exotic materials requires an accurate data logging system. Pre-loaded with VNC interface software as standard, remote assistance and software updates can be provided wherever in the world the equipment is based.

With the latest software advances, TVC have several layers of user interfaces enabling operators to digitally interface with IoT and Industry 4.0 compliance at all levels, facilitating the smooth digital exchange of welding data. The innovative software and electronics allow the monitoring, capture and analysis of pulsed welding processes.

The unit, screen and keyboard are supplied in a single rugged case with the system accessories and probes supplied in a probe carry bag which can be shipped internationally by road, sea or air transportation.
