AC discharge curve

  • The input power is alternating current. After passing through the power switch, it enters the main circuit and control circuit. Then transformer steps down the high-voltage alternating current into suitable welding low-voltage alternative current. The alternative current has the alternating characteristics of positive and negative changes. When it passes through the electrode and welding parts, it generates high temperature and melts the solder, thereby achieving welding.

Applications

Industry applications
  • General industry
Application material
  • Low-carbon steel
  • Stainless steel
  • Non-ferrous metals

Welding result

  • The depth of the weld's melting meets the design requirements, ensuring the strength and integrity of the welded joint.
  • The color of the welded area closely matches that of the base material, resulting in a consistent overall appearance.
