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.

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
