  Pipes with different diameters are equipped with different positioning guide rings, and the guide rings are driven by rack and pinion;

  Self-contained integrated wire feeder realizes unwinding wire feeding;

  Automatic arc length tracking, yaw cover function;

  The efficiency of hot wire welding is 3~5 times higher than that of cold wire welding;

  The groove form of the workpiece can be V-shaped or U-shaped;
