Main circuit working principle

1. The control circuit of this machine uses an integrated circuit to output phase-shifting pulses. The phase-shifting pulses are sent to the trigger pole of the anti-parallel thyristor in the main circuit through power amplification. The magnetization and demagnetization currents are adjusted by changing the phase of the thyristor conduction angle. the size of.

2. When the work selection switch is in the "magnetization" position and the handle button or foot switch of the strut probe is pressed, the magnetization indicator light will light up and the magnetization current will be output.

3. When automatic demagnetization is required, set the work selection switch to the "demagnetization" position, the demagnetization indicator light will be on, and press the handle button or foot switch of the strut probe. The equipment output will automatically attenuate the AC current, so that the magnetic field in the part will change from large to large. to a small decay until it reaches zero.
