  • A rectifier for welding has voltage/current characteristics as Drooping.
  • When a rectifier for welding has voltage/current characteristics that are drooping, it means that the voltage decreases as the current increases. This is also known as a drooping characteristic curve.
  • In a welding application, this type of characteristic curve can be advantageous because it helps to stabilize the arc during the welding process.
  • As the current increases, the voltage drops, which prevents the arc from becoming too long and unstable.
  • The drooping characteristic curve can also help to prevent overheating of the welding material. By limiting the voltage as the current increases, the heat input to the material is controlled, which can help to prevent distortion or damage to the welded part.
