DETAILS

A mild steel, metal-cored wire designed for superior arc performance in high deposition, high travel speed applications requiring minimal amounts of spatter, improved arc wetting action, and enhanced silicon island management.

Features

  • H4 diffusible hydrogen levels
  • Low spatter and excellent arc stability
  • Deoxidizing agents minimize pre- and post-weld clean up
  • Enhanced silicon island management
  • Low temperature impact properties - charpy V-notch test results capable of exceeding 40 J (29 ft·lbf) at -45°C (-50°F)
  • Excellent bead shape and profile

Typical Applications

  • Robotics/ Hard automation
  • Structural fabrication
  • Process piping and pressure vessels
  • Shipbuilding
  • Heavy fabrication

Welding Positions

  • Flat/Horizontal

Shielding Gas

  • Mixed Shielding Gas

NOTES

Note
⁽⁵⁾To estimate ESO, subtract 3/16 in (4.8 mm) from CTWD.
⁽⁶⁾For greater percentage of CO2 shielding gas, increase voltage by 1-2 volts.
