70S-3 Mild Steel MIG Wire

INTRODUCTION

Aufhauser 70S-3 is a silicon and manganese deoxidized wire for mild and low alloy steel general purpose fabrication. A well balanced silicon and manganese content permits its use with CO2, argon-oxygen mixtures, or mixtures of the two. This wire may be used for short-circuiting arc (dip-transfer), buried arc, as well as spray transfer arc processes. Aufhauser 70S-3 produces quality welds with rimmed steels, better welds on killed steels. It yields an almost slag-free deposit, which does not require cleaning for many applications, thereby providing low plate preparation costs, good bead appearance and welder satisfaction.

APPLICATIONS

  • Welding steels with dirty or rusty surface
  • (UNS numbers K02600, K02801, K02001, K02700)
  • Single-pass welding of killed, semi-killed, and rimmed steels
  • May be used for some multi-pass applications
