Description
An electrode wire, copper-covered, with an addition of deoxidizers Mn and Si for semi-automatic welding in the shield M21 (80% Ar + 20% CO2) and mixture M21 (Ar + CO2). Metallurgical properties of wires provide high-quality welds and reliable wire feed in the mechanised welding process. Working temperature of welded joints from (-20°C up to 350°C). MULTIMIG 3 is intended for welding non-alloy structural, boiler, shipbuilding and low-alloy C – Mn steels with increased strength.
