Mao Xin Machinery Co., Ltd is the pioneer of manufacturing transistor high frequency welding machines in Taiwan. The welder is including four types: (1) transistor high frequency carbon steel welder, (2) transistor high frequency aluminum welder, (3) transistor high frequency stainless welder, (4) transistor high frequency copper welder. 

Jeng Dar’s welding machine is adapted from advanced technologies utilized in Western countries. Its rated power is from 100KW to 800KW. The unique professional design ensures maximum welder efficiency and consistent weld frequency for low cost operation. The efficiency of this specific transistor type welder is much more advanced and than traditional vacuum tube welders. The welder also provides a number of protection features to prevent arc-over and coil short circuit failures. 

The feature of Jeng Dar's transistor high frequency carbon steel welder includes five parts-

(1) Low voltage transformer device:

      The voltage of three phase transformer system is low and stable. This transformer is more  
      secure than high voltage type's.

(2) D.C power supply cabinet:

      The D.C power supply is adapted low voltage circuit system and semiconductor technology.

(3) High frequency oscillator output cabinet:

      This device is constituted by a parallel with MOSFET power module. Each single module is 
      carrying 50kw, operational frequency is 250Khz ~ 400Khz.

(4) Distilled water cooling circulation system:

      This system is adopted the plat pattern of the heat exchanger to reduce the heat and maintain 
      the welding machine at a safe working temperature range.

(5) PLC control system console:

      This control system can quickly display fault diagnosis for rapid and effective maintenance.
