generators and caters to the diversified applications of tube welding and heat treating industries. The features of this new generator include a frequency range of 500Hz to 440kHz at an output range of 2kW to 1,000kW, a power factor of 0.95, and power conversion of 90 per cent efficiency. In cases of short time heating, the generator provides increased output power to solve problems. 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. The comprehensive solid-state and low- voltage system forms 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 thus been achieved. The water cooling circulation system (optional) helps to address concerns with water temperature levels and helps prevent problems.

In addition to Hisen’s transistor generator, the company also provides quality high frequency machines such as high frequency pipe welding machines (transistor generator and vacuum tube), high frequency induction heaters (transistor generator and vacuum tube), and high frequency preheaters for the semiconductor and melamine industry.
