15AK Contact Nozzle Shield Nozzle Welding Gun Consumables Set

• Describe

  1. Core functions of the conductive nozzle ‌
  ‌Current conduction hub‌:
  As the only current contact point between the welding gun and the welding wire, it accurately conducts the welding current to the end of the welding wire;
  The inner hole diameter must strictly match the welding wire (usually 0.02mm larger) to ensure smooth wire feeding and stable conduction.
  ‌Arc stability guarantee‌:
  The copper material (partially containing chromium zirconium copper) provides high conductivity, reduces energy loss, and avoids arc breaking during welding;
  The precise inner hole structure guides the welding wire to output vertically to maintain arc concentration.

  
  2. Core functions of the protective nozzle ‌
  ‌Gas flow field control‌:
  Guide the protective gas (such as CO₂) to evenly cover the molten pool, isolate the air and prevent the weld from oxidizing;
  The conical cavity design accelerates the gas flow rate and enhances the ability to resist wind interference.
  ‌Anti-splash protection‌:
  The surface is treated with a special coating to significantly reduce the adhesion of welding slag;
  Wrap the outside of the conductive nozzle to block the impact of metal splashes and reduce the loss of the conductive nozzle.
  ‌Key features of the protective nozzle‌ Specifications
  ‌Coating process‌ 15AK anti-sticking slag coating
  ‌Structural adaptation‌ Standardized threaded interface (M6), direct connection to the welding gun gas system
  ‌Maintenance advantages‌ Smooth surface, easy cleaning, reduced downtime
  Conductive nozzle: Replace immediately when the inner hole expands ≥0.1mm or elliptical deformation occurs;
  Protective nozzle: Replace when the coating peels off or the inner wall accumulates slag seriously;
  ‌
  
  Safety protection‌: Be sure to wear a welding helmet + gloves during operation to protect against arc radiation and splash burns.
  ‌Note‌: Poor quality accessories can easily lead to unstable conductivity and failure of gas protection. It is recommended to use a pure copper conductive nozzle + coated protective nozzle set
