NS-115 CopperFree™ is a mild steel solid filler wire containing a high combined total of manganese and silicon. The wire produces a smooth, uniform welding arc, which minimizes weld spatter and results in excellent bead appearance and high operator appeal. The excellent operating characteristics of NS-115 appeal to users seeking better performance in their ER70S-6 applications.

CHARACTERISTICS

NS-115 CopperFree™ provides the ultimate in flexibility to support your GMAW operations.

  • Cast of 35″ (.88m) to 55″ (1.3m) and Helix below 1″ (25.4mm) improve feedabiltiy and provide accurate wire positioning
  • Higher Silicon content reduces the molten metal surface tension, resulting in flatter bead profiles
  • Manufactured according to ISO9001:2008 quality standards
  • Excellent arc starts, arc stability and feedability
  • Minimal spatter
  • No copper flaking
  • High level de-oxidizers • Excellent weld appearance and post weld cleaning

APPLICATIONS

All metal transfer modes of GMAW

Robotic, mechanized or semi-automatic welding

Welding steel with medium to heavy mill scale, light rust or thin oil

Single and multi-pass weldments

Applications requiring a minimum 70,000 psi tensile strength

TYPICAL APPLICATION SHIELDING GAS BLENDS

100% CO2

75-95% Argon/Balance CO2

95-98% Argon/Balance O2

Flow Rate: 35-50 CFH

WELDING POSITIONS

All position welding is possible when using the correct shielding gas blends, welding process and welding parameters.

STORAGE

Welding wire should be stored in a dry, enclosed environment and in its originally-sealed package.
