 DIN 8559 :  SG 2
 EN 440 :  G3 Si 1
 Description and Applications
 Arctech SG 2 is a copper coated mild steel solid wire electrode suited for
 universal application in tank, truck bodies farm equipment, structural and
 carbon steel fabrication. Also due to its high current carrying capacity it is
 recommended for light gauge and heavy weldments in general shop
 fabrication where moderately scaled and rusty plates are frequently
 welded.
 It provides largely spatter free metal transfer and excellent weldability
 with powerful desoxidizers for Argon rich Ar/Co2 mixtures and even for CO2.
