tedious.
Correct welding position
The welding position presented is described for right-handed, in the case of left-handers will look exactly the opposite.

3. Put your left elbow to the left side of the body. If
you can weld with both hands.
This will better control electrode.
Try to weld from left to right (if you're right-handed). You will see more precisely the welding area.

Keep the electrode at a slight angle as shown in the figure.

electrode at about 3mm to stabilize the arc.

sticks or the traffic is too fast and the arc is interrupted.
Proper arc length
Arc length is the distance from the end of the electrode to the workpiece. Once the arc is stabilized setting proper arc
length is very important. Arc should have
