Welding wire diameter in constant voltage (CV) mode Donot support welding above 3.0mm (CV) Support welding above 3.0mm ( CV )
Very little heat input and less welding deformation
Welding wire diameter in constant current (CC) mode Donot support welding below 3.0mm (CC) Supports welding below 2.5mm. (CC)
Suitable for high-speed welding of thin plates
Deposition rate Equivalent to standard submerged arc deposition rate 25%-30% higher than standard submerged arc under the same conditions
Welding performance of S.S./nickel-based alloys welding Good welding performance Perfect welding performance
Wire feed control technology CC uses submerged arc control technology
CV uses constant speed wire feeding
CC/CV use arc voltage sensing technology

Advanced features

  • Wire diameter as small as 1.2 mm
  • Minimum wire diameter up to 1.2 mm, strictly control the line energy of the welding joint achieves small heat affected zone, less distortion. With these, it is very suitable for thin plate welding with high welding performance, such as medical, food-grade, stainless steel welding and high-alloy steel welding.

  • Superior Stainless performance
  • The ultra-precise control of the welding current, voltage and speed ensure uniform composition welding seam, smooth and beautiful shape, excellect and stable welding quality.

  • Hardfacing (with arc voltage feedback technology)
  • Hardfacing is a surface engineering technique that improves the performance of a workpiece by adding one or more alloy layers with higher hardness and wear resistance to the surface of the metal substrate.
    • Very uniform weld bead penetration;
    • Higher deposition rate(60%-80%);
    • The cladding layer does not have concentrated solidification lines, so the cladding layer has less crack sensitivity;
    • Very smooth surface of the cladding layer, which can greatly reduce the number of cladding passes and overlaps;
    • Strong repeatable productivity.

  • Robot ready
  • • Higher deposition rates at faster travel speeds;
    • Increased productivity and arc-on time;
    • Fast digital system component communication.
