2. Main Applications
- Weldable materials: Carbon steel, stainless steel, alloy steel, aluminum and aluminum alloys.
- Main industries: Steel structure, mechanical parts processing, shipbuilding, transportation and other heavy industries.
- Especially suitable for thick metal plate welding for shipyard and steel structure projects.
3. Welding Production Advantages
- Cost saving: Reduce consumption of welding wire and shielding gas, and cut post-weld cleaning work.
- Excellent weld quality: Smooth and beautiful weld seam, no cracks, incomplete fusion, blowholes or other defects. Low spatter, no undercut, well-formed weld root.
- High efficiency: Store and recall up to 100 groups of welding parameters, no need for manual repeated recording, greatly saving operation time.
- Stable arc performance: Fast arc dynamic response, concentrated energy and strong penetration. Arc keeps stable even when wire stickout changes.
- Suitable for both manual semi-automatic and automatic welding equipment.
