Welding Wire ESAB OK Autrod 12.50 D200 5 kg Spool SG2 G3Si1

ESAB OK AristoRod 12.50 Welding Wire D200 5 kg Spool SG2 G3Si1

• Welding wire SG2 / G3Si1
• Non-copper-coated wire electrode
• Excellent wire feeding behavior
• Less post-weld cleanup
• Suitable for high welding currents
• Original ESAB quality

 

The ESAB OK AristoRod 12.50 is a non-copper-coated solid wire electrode of the G3Si1 grade for GMAW (gas metal arc welding). It can be used with shielding gas groups M20, M21, and C1 according to EN ISO 14175.

The welding wire is particularly suitable for joining general structural steels, pipe steels, shipbuilding steels, and fine-grain structural steels with yield strengths up to 420 MPa. Typical materials are P235 or S235 up to P420 or S420 and comparable steels.

Thanks to its optimized chemical composition, the OK AristoRod 12.50 enables consistent welding performance and reduces the need for rework. The excellent wire feeding behavior supports both high welding speeds and long wire feed distances.

The wire is particularly well-suited for applications involving high welding currents. In larger Marathon Pac™ containers, it can also be used excellently in automated systems and robotic welding.

TÜV certification confirms its use at temperatures down to -50 °C. This makes the welding wire suitable for components requiring high impact toughness at low temperatures.

General fields of application: steel construction, mechanical engineering, vehicle construction, shipbuilding, pipeline construction, pressure vessel construction, as well as automated and robot-assisted welding applications.

The disposal of this product, as well as its residues and waste, must be carried out in an environmentally friendly manner and in compliance with local disposal regulations. Please use suitable recycling routes whenever possible.
