NS-101 CopperFree™ is a premium copper-free mild steel solid filler metal designed to extract maximum weld quality and user appeal from ER70S-3 wire. Careful attention to the manganese and silicon contents assure maximum deoxidation, flat bead profiles and low-spatter welds.
NS 101 CopperFree™ provides the ultimate in flexibility to support your GMAW welding operations.
- Cast of 35″ (0.88 m) to 55″ (1.3 m) and helix below 1″ (25.4 mm) improve feedability and provide accurate wire positioning
- Manufactured according to IS09001:2008 quality standards
- Excellent arc starts, arc stability and feedability
- Minimal spatter
- No copper flaking
- Moderate de-oxidizers
- Excellent weld appearance and post weld cleaning
Low carbon killed and semi killed steel
Well suited for all metal transfer modes of GMAW
Robotic, mechanized or semi-automatic welding
Welding steel with light mill scale, light rust or thin oil
Single and multi-pass weldments
Pipe welding, structural steel and steel buildings •
Applications requiring a minimum 70,000 psi tensile strength
TYPICAL APPLICATION SHIELDING GAS BLENDS
75-95% Argon/Balance CO2
95-98% Argon/Balance O2
Flow Rate: 35-50 CFH
All position welding is possible when using the correct shielding gas blends, welding process and welding parameters.
Welding wire should be stored in a dry, enclosed environment and in its originally-sealed package.
