WELDING ELECTRODES MP-3 FLAGMAN GREEN

Electrode Description

When stored properly, they do not require baking before welding. In case of dampness, bake at 90–100°C for 30 minutes (for ø 2.5 and 3.0 mm) or at 120–130°C for 1 hour (for ø 4.0 and 5.0 mm).

Deposition efficiency: 8.5–9.2 g/A·hr.

Electrode consumption per 1 kg of deposited metal: 1.69 kg.

Application Range

MP-3 FLAGMAN Green electrodes are intended for manual metal arc welding of any structures made of carbon and low-alloy steel. Welding can be performed even by a novice welder using budget-segment welding machines. These electrodes are irreplaceable when welding in "field conditions" at low current. The metal surface can be wet, with traces of rust or other contaminants. The MP-3 FLAGMAN Green electrode melts quietly during welding, creates almost no spatter, and forms a fine-ripple weld bead. Upon cooling, the slag lifts by itself, leaving the weld clean without additional mechanical effort.
