Narrow Gap SAW




  • Oscillating tip, left-mid-right three position welding position, oscillating assembly is stable and reliable.
  • Chromium Zirconium Copper contact tip, alloy copper material torch soft connection with good conductive, those can increase life span.
  • Torch body is made of stainless steel and plasma paint technology,
  • Automatic flux feeding and recovery and sensors to sense sidewall variations.
