Standard Arc® S-3 is a copper-coated 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 lowspatter welds.
Standard Arc® S-3 Copper-Coated Welding Wire supports your GMAW operations.
Cast of 35″ (.88m) to 55″ (1.3m) and Helix below 1″ (25.4mm) improve feedability and provide accurate wire positioning.
Manufactured according to ISO9001:2008 quality standards
Excellent arc starts, arc stability and feedability
Minimal spatter and copper flaking
Excellent weld appearance and post weld cleaning
Low carbon killed and semi killed steel
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.
