Constant Power

Constant power works by measuring the voltage across and current drawn by the load. Current control circuits are used to accurately control output current of a power supply and can be used for applications with significant variations in electrical resistance from weld to weld, including applications where the plating erodes and builds-up on the face of the welding electrodes. Constant power mode:

  • Varies current and voltage for consistent energy
  • Breaks up surface oxides and plating
  • Is ideal for automation to extend electrode life
