WELDING ELECTRODES MP-3

Electrode Description

When stored properly, they do not require baking before welding. In case of dampness, bake at a temperature of 140–150°C for 30 minutes.

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

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

Application Range

MP-3 electrodes are designed for welding any structures made of carbon and low-alloy steel. Welding can be performed even by a novice welder using budget-segment welding units. They are absolutely essential for field welding operations at low current. The surface can be damp and contain traces of rust or other impurities.
