▎Applications and Features

  • The shielding gases include Ar/CO2 blends. All Positions electrode or single pass welding with high speed.
  • In welding metal, there is a lower oxygen level due to the excellent de-oxidative ability.
  • Ideal for ship-building, vehicles, bridges and pipes with less spatters and arc stability
