Usage

 :
Usage Guidance (How to Use) :

  • Connect the welding machine to a 380 400V three phase power source.
  • Attach the electrode holder and ground clamp securely.
  • Insert the appropriate electrode 1.6 5.0mm based on the welding task.
  • Adjust the output current using the control knob according to material thickness.
  • Turn on the welder and check the LED display for correct parameters.
  • Strike the arc by tapping the electrode on the metal surface.
  • Maintain a stable movement and correct arc length for a smooth weld bead.
  • After welding, switch off the machine and allow it to cool before storing.

Maintenance Guidance :

  • Clean dust and debris regularly from vents for proper airflow.
  • Inspect cables, electrode holder and ground clamp for wear.
  • Store the machine in a dry, cool area to protect against moisture.
  • Avoid overloading by following the recommended duty cycle.
  • Check connections periodically to ensure stable operation
  • Allow adequate cooling time after continuous welding sessions.
  • Do not use in wet environments due to IP21S protection level.
