AT-1 SubArc Tractor

  • Exceptional tracking control and self-steering in most applications leave the operator free for quality control, joint cleaning and flux handing;
  • Welds butts, horizontal fillet and lap joints to the left or right side of the tractor frame for convenience;
  • Close mechanical alignment between wire and joint maximizes weld quality with no fixturing costs;
  • Using PWM control technology to ensure precise and stable traveling.
  • ArcTractor Controller

  • With Arc Voltage Sensing Technology, heat input is reduced and deposition rate is increased by 30%. This technology also ensures stable welding arc over a wide range of parameters and precise output control;
  • Scratch and direct start methods.

    AH-1 SubArc Welding Head

    - The pre-selection of nominal values for welding current, arc voltage and speed in coordination with the SubArc-1000XD /1250XD power source ensures a high degree of automation;

    - The AH-1 welding head has an automatic ignition and automatic burn-back with withdraw for an optimized welding process;

    - The welding head also has adjustment to angle forward or backwards by up to 45 degrees & side to side by up to 45 degrees;

    - All welding heads are equipped with a laser pointer and a mechanical pointer for visual seam tracking. Via a cross support, the AH-1 can be manually positioned with an effective adjusting range of 100mm each;
