EN ISO CODE: 14341-B G 49A 3 C1 S6
Autotherme-1 is a copper coated mild steel GMAW wire for welding of mild steel, low carbon steel and other structural steels of tensile strength up to 540 MPa. The wire burns with smooth arc and minimum spatter under optimum welding conditions. It is designed for single and multi-pass welding of low and medium carbon steels like; SA-36, A/B/C/D grades of SA-283, A/B/C grades of SA-285, A/B grades of SA- 414, etc.
