With proper operation and regular maintenance, high-quality power tools can last well beyond their warranties. Unfortunately, tools with advanced electronics and circuit boards—such as the Leister VARIMAT V2—also require the right power sources for maximum life and performance.
When using an AC-power commercial portable generator, the consistency of the electric current is specifically important. On most generators, this is listed as total harmonic distortion (THD). The higher the THD, the greater the fluctuations in current flow. If THD is too high, it will overheat critical components, and if it is too low, it will negatively impact performance.
In this post, we will explain total harmonic distortion’s impact on power equipment, and detail what you need to consider when purchasing a commercial portable generator for your construction site.
