The HF27 High Frequency Inverter precisely controls and monitors electrical AND mechanical weld parameters. Miniature welds are highly sensitive to small heat profile fluctuations in the resistance welding process. Overheating deforms and destroys parts, while under heating results in a weak, unacceptable bond. To achieve consistent, reliable welds of small to microminiature parts, precisely controlled heating is required. This necessitates superior control of the energy output.

The HF27 is available with a built-in, fully integrated displacement monitor for use with Miyachi Unitek weld heads. A linear variable differential transformer (LVDT) provides displacement feedback to the HF27.
