The comprehensive solid-state and low- voltage design helps to make a compact design that reduces the required installation space. A reduction to one-third of the space required by other conventional vacuum tube oscillator models has been achieved. Transistors, printed circuit boards and other components have all been strategically placed for easy maintenance. An optional water cooling circulation system can help address concerns with water temperature levels and deal with them proactively. Full protection is provided against coil touch,

abnormal water flow, abnormal water inlet/ outlet temperature, low/high frequency, over voltage and over current. In addition to Hisen’s top-of-the-line transistor generator, the company also pro- vides high frequency pipe welding machines and high frequency induction heaters (transistor generator and vacuum tube).

A pioneer in high frequency machines Hisen Enterprises Co Ltd, founded in 1967, has been one of the foremost pioneers in transistor generators for pipe welding and high frequency heat treatment machines. Its products are mainly exported to Thailand, Malaysia, the Philippines, Indonesia, Vietnam, mainland China, Saudi Arabia, India, Pakistan, the UAE, Kuwait and North Africa. A new transistor generator, developed using the company’s latest technologies, utilises new-type transistor devices, and has reduced the size of the conventional transistor generator. It also provides enhanced flexibility to meet the diverse applications of the tube welding and heat treatment industries. The new generator has a frequency range of 500Hz to 440kHz at an output range of 2kW to 1,000kW, power factor of 0.95, and power conversion of efficiency 90 per cent. Because transistors are used instead of vacuum tubes, the level of input power can be reduced by over 22 per cent, and cooling water can be saved by up to 50 per cent.
