The HF25 Series controls address the challenges of microjoining. 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 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 micro miniature parts, precisely controlled heating is required. This necessitates superior control of the energy output.
CONTROL FEATURES:
Constant current, voltage, and power modes
Monitors energy and resistance
Force control
Monitor displacement and force
Max 2400A at 25kHz electrical feedback |

Vyper Variable Speed Drive
The Frick® Vyper Variable Speed Drive for screw compressors offers the refrigeration industry superb system performance, enhanced energy savings, and reduced maintenance costs. The Vyper VSD provides fast, precise, and wide-ranging response to rapidly changing loads. The liquid-cooled, NEMA 4 rated cabinet provides protection from ammonia vapors while the QuantumLX control panel provides a user-friendly interface for ease of operation. The drive is available in 150, 305, 435, 687 and 957HP models and can be mounted either directly on the compressor package or remotely. The package mount method provides easy on site installation of new equipment while the remote mounting method offers an easy solution to retrofitting a constant speed drive with the Vyper VSD for energy cost savings and or enhanced performance. The Vyper drive includes an IEEE-519 Harmonic filter for line side power signal conditioning. The filter can be deducted if it is determined not necessary. No other variable speed drive on the market offers the performance and features of the Frick® Vyper VSD. Quick response to load variations, make the Vyper VSD ideal for industries such as bottling plants. |

| The ISA range of Inverter power supplies provides the highest level of control available today in large scale resistance welding. The ISA-500AR, ISA-1000AR and ISA-2000AR are intelligently packaged in “NEMA” style enclosures and are designed to deliver robust performance in the harshest of production environments. The ISA models can deliver 500, 1000 and 2000 amps of primary welding current, respectively. |
