QQ-150 Air-Cooled Anti-Scalding TIG Welding Gun

• Describe

  Core Advantages ‌
  ‌Efficient heat dissipation design‌: Adopting an air-cooled heat dissipation system (air cooling), the temperature of the gun body is stable during continuous welding, avoiding overheating and scalding, and is suitable for long-term operation.
  ‌Strong and durable‌: The gun head is made of thickened copper material, the conductive nozzle and the porcelain nozzle are resistant to high temperature wear, and the service life is more than 40% longer than that of ordinary welding guns.
  ‌Flexible operation‌: Supports single-handed control of wire feeding/arcing, the bending pipe assembly is torsion-resistant and anti-winding, and it is more convenient to operate in narrow spaces.

  
  Core Selling Points ‌
  Performance configuration ‌
  ‌Wide compatibility‌: Current range 150A-250A ‌Cable upgrade options ‌: Provide ‌6 square copper wire (basic version)‌ or ‌10 square copper wire (industrial version)‌, the current transmission is more stable and energy loss is reduced.
  ‌Modular maintenance‌: Accessories such as conductive nozzles and protective porcelain nozzles support single-piece replacement, and the maintenance cost is low (such as the unit price of porcelain nozzles is about 0.5 yuan).

  
  Flexible Customization
  Configuration items Optional specifications
  Wire length 2 meters (narrow space), 4 meters, 5 meters, 8 meters, 10 meters, 13 meters, 15 meters, 20 meters
