14AK Durable Conductive Nozzle‌ Protective Nozzle‌ Connecting Rod Set

• Describe

  ‌Conductive Nozzle‌
  ‌Function‌: Conduct current to welding wire to ensure stable arc focusing
  ‌Material‌: Pure copper (high conductivity)
  ‌Specifications‌ (10 pieces/pack):
  ‌Aperture‌: 0.8mm, 1.0mm, (precisely matching welding wire diameter)
  ‌Length‌: 25mm (standard type)

  
  Protective Nozzle‌
  ‌Function‌: Guide protective gas to cover the molten pool to prevent splashing and adhesion

  
  Connecting Rod‌
  ‌Function‌: Connect the welding gun body and conductive nozzle to support current conduction
  Adaptability and purchase points‌
  ‌Aperture matching‌:
  The aperture of the conductive nozzle must be larger than the wire diameter by 0.02mm (for example: 1. 0mm welding wire with 1.02mm aperture)

  
  Durability Priority
  Economic scenario: Brass protective nozzle (cost-effective)
  High frequency/high temperature scenario: Copper or ceramic protective nozzle (strong corrosion resistance)
  Sealing Upgrade:
  For deep seam welding, choose a screw protective nozzle + a screw connecting rod to prevent gas leakage

  
  Maintenance Suggestions
  Conductive nozzle: Replace immediately when the inner hole expands ≥0.1mm to avoid arc deviation
  Protective nozzle: Replace when the surface welding slag accumulates more than 50% or the coating peels off
  Connecting rod: Check the thread wear every month and replace it if it is loose (to prevent poor contact)
