Description

Welding Fume Purifier

An electronic communication group: 232586710, 345731137.

  • The fan uses a 6038 violent fan (four-wire with PWM speed regulation function).
  • The power supply interface uses a DC interface and a TYPE-C interface (power supply voltage 12V).
  • Among them, the TYPE-C interface input uses a PD deception chip, and the deception voltage is 12V to power the entire circuit.
  • A 5V linear regulator provides a 5V voltage source, and the potential of 0~5V is adjusted to the GP9101 through a potentiometer.
  • This allows GP9101 to output a PWM signal with a duty cycle of 0%~100% to adjust the fan speed.
  • The shell is 3D printed, please see the attachment for related model files.

 

 

Change Log

Updated to version V1.2 on June 17, 2023.

The deception chip is changed from FS312HC to HUSB238.

Added PWM signal phase selection pad to solve the problem of some fans turning the potentiometer clockwise to reduce the air volume.

Add an external exhaust adapter ring with a diameter of 50mm, which can be adapted to an exhaust pipe with an inner diameter of 50mm. The harmful gases can be completely discharged to the outdoors through the exhaust pipe.
