▎Applications and Features

  • KM-58Z is a non-copper coated wire for welding 490N/mm² grade steel.
  • Ti addition in the wire reduces droplet size, stabilizes the arc and decreases spatter at high current.
  • Suitable for high-current welding of thick plate butt joints, fillet welding and horizontal welding.
  • Ideal for welding steel structure, ship-building, bridge and machinery.

▎Welding Instruction

  • Please refer to Appendix B.
