Weld Monitor Applications
Power Supplies with a “Built In” Weld Monitor - The Pros & Cons
Graphical interfaces with weld monitoring capabilities add cost and functionality to a welding power supply. Internal power supply monitors can be a useful operational feature BUT from a Quality Control standpoint, it is important to consider and understand the true level of “independent checking” that such weld monitors offer.
Typically internal weld monitors will use the same signal sensors and referencing electronics for monitoring as are also used to derive the power supply output. This is fine with all being well, but an important consideration is to understand what happens if one or more of those items goes wrong or becomes inaccurate ?
In view of this, well controlled production environments such as Aerospace, Medical, Automotive etc.. often deploy external weld monitors in applications where high end power supplies also have an internal weld monitor. This quality assurance consideration ensures that something is always checking the internal checker and that an independent Quality verification is always taking place.
- The Weld Monitoring Unit is designed specifically to deliver low cost, truly independent real time actual weld energy checking.
