4.1 Working principal
INTIG 401 PULSE series welding machine adopts IGBT as the main circuit
switch. The three-phase AC input power inverted to 20KHz mid-frequency current
through the rectify of the full bridge. Then through the filter and current negative
feedback control to get the constant adjustable welding current.
The control circuit will control the output current through the adjusting of the
pulse width. The negative feedback signal, which is the real welding current get
from the output current sensor, put into the special PWM circuit after compared with
the current adjust signal, then output the driving pulse to control the IGBT, so that
the output current will keep stable to get descending external characteristic.
This machine has functions of gas pre send, gas post cut off, HF arc striking,
current up-slope, current down-slope. All these functions are controlled by the
digital signal controller automatically.
