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.

CHARACTERISTICS

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
