Features
- Copper coated, manganese-silicon alloyed rod optimized for GTAW on general engineering and structural steels (minimum yield strength 420 MPa).
- Designed for welding with pure argon shielding gas (I1) for clean, consistent welds.
- Optimized chemistry reduces post-weld rework and lowers overall cost of ownership.
- Available in Marathon Pac cardboard bulk drum packaging for efficient storage and handling.
- Excellent feeding performance for high-speed welding and long feeding distances.
- Typical tensile properties (as welded, EN Ar (I1)): yield strength 470 MPa; tensile strength 560 MPa; elongation 26 %.
- Typical Charpy V-Notch impact values (as welded, EN Ar (I1)): 70 J at −30 °C; 60 J at −40 °C.
- Classification per EN ISO 636-A and SFA/AWS A5.18: W 42 3 3Si1; W 3Si1; ER70S-6.
- Approved to CE and UKCA EN 13479 and VdTÜV 11842 standards.
- Weld metal analysis (Ar): C 0.05 %; Mn 1.4 %; Si 0.8 %; S 0.015 %; P 0.015 %.
- Wire composition: C 0.078 %; Mn 1.46 %; Si 0.85 %.
