Cavitar C400-H Welding Camera System

The Cavitar C400-H Welding Camera System is a complete, compact, ready-to-use weld visualization solution with a camera, integrated laser illumination, and optics adjustable to almost any welding application.  The C400-H uses cutting-edge technology combined with laser illumination to handle the intense light from a welding arc. Easy to set up and versatile, this weld monitoring system is suitable for quality assurance, machine vision, and welding research applications.

The Cavitar Welding Camera delivers clear, high-resolution images of various popular welding techniques such as GMAW (MIG, MAG) and GTAW (TIG). It also handles all major beam welding processes, including CO2 laser, fiber laser, diode laser, Nd: YAG laser, and electron beam techniques.

Use cases include real-time adjustment of welding parameters for automated welding processes such as tube seam welding. At the same time, operators may perform their work at safe distances away from the arc, heat, and dangerous fumes.

The camera's compact design allows it to be implemented into the most challenging and space-restrictive remote applications.  Supplied cooling channels and camera housing heat sinks ensure the survivability of the camera in these harsh environments. 

Adjustable optics allow the camera to be tuned in an application-specific implementation, ensuring it is the right welding camera tool for the job.
