Calibrating Modern Welding Power Sources - Necessity or Necessary Evil?

Welding power sources fundamentally pose a high potential electrical danger due to the high welding currents and voltages. Nevertheless, the risk is reduced to a minimum by compliance with current electrical engineering standards right from the development stage and the use of high-quality electrical components, especially in the case of systems intended for commercial use. Reputable power source manufacturers and professional service technicians can provide more detailed expert advice on the subject.

To ensure work is carried out in accordance with the applicable standards, regular calibration of welding power sources, generally once a year, is necessary, even though modern power sources very rarely show any unacceptable divergence from the specified values. In practice, however, it has been shown that annual inspections frequently reveal safety-related defects on the welding power sources that could certainly pose a danger to the welder. For that reason alone, it is an obvious step to have the inspections regularly performed and documented by qualified service technicians, even if it may not appear necessary for high-quality welding power sources at first sight. Only in that way is it possible to sustainably ensure that all health-and-safety and quality-related aspects are complied with, which in turn contributes to the safety of the welder, customer satisfaction and financial success.

Welding power source manufacturers can significantly influence the quality and safety of a system by various means such as the use of high-quality electronic components and comprehensive quality controls. That is why, at voestalpine Böhler Welding for example, every circuit board in a welding power source is manufactured on the in-house PCB production line in Cittadella, Italy, checked by a 3-stage quality assurance process and sensitive electronic components are protected by an extra coating of lacquer. What is more, every single power source is put through a static and dynamic end-of-line test before shipping.
