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 low spatter welds.
CHARACTERISTICS
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
Moderate de-oxidizers
Excellent weld appearance and post weld cleaning
APPLICATIONS
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
