MS 200

Unitor MS 200 is a Gas welding rod for welding of unalloyed and low alloyed structural steel. It can be used for welding thin as well as heavier sheets.

Select the diameter of the wire according to the thickness of the workpiece. Clean all rust, scale and old paint from the area. In general, gas welding of unalloyed steel is suitable for thin sheets and pipes of small diameters, where the wall thickness does not exceed 6 mm. For larger dimensions it may be advantageous to use electric arc welding with coated electrodes. The MS rod is specially suited for gas welding, having a viscosity that makes in-position gas welding easy. Select the blowpipe according to the thickness of the workpiece. The flame should be neutral. Workpieces less than 4 mm thick should be welded with the Leftward technique, thicker workpieces should be welded Rightwards. Do not overheat the workpiece. Maximum temperature of the workpiece should be 350°C.

Gas welding rods including our MS 200 for mild steel have a low silicium contents in order to perform satisfactorily when gas welded. TIG welding rods have a high silicium content making the molten pool fluid. It is therefore important that Gas welding rods are not used for TIG welding and vice versa.
