MMA Welding technique
The welding is started by sharply striking the bottom of the groove with the welding electrode. After this, move the welding electrode back to the beginning without stretching the arc, and move the electrode easily while monitoring the width of the molten weld pool. Move the welding electrode at a pulling angle. The boundary of the slag formed is visible after the molten weld. It must be behind the molten weld. The distance of the slag boundary from the molten weld can be adjusted with the welding current and the angle of the electrode.
Throughout the welding, concentrate on the length of the arc and keep it as short as possible. The length of the arc increases easily as the electrode decreases in length during the welding. The movement may be somewhat difficult to control at first but it is easy to get accustomed.
When the welding electrode runs out, one needs to remove the slag from the previous weld and clean it with a steel brush. Ignite the next electrode slightly ahead of the previous weld and then move the welding electrode back to the previous weld and continue with the welding.
End welding by moving the welding electrode slightly back to the completed weld and then lifting the electrode straight away from the work piece.
