The feature of 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.

A field effect transistor (FET) converts changes in input voltage into changes in output current. The gain of a FET is equal to its transconductance, defined as the ratio of the change in output current to the change in input voltage. Commonly available on the market are generally N-channel and P-channel.
