Want this question answered?
Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
3/8 inch
A rule of thumb is - the arc length should be the same as the diameter of the electrode. 3/32" electrode = 3/32" arc length. 1/8" electrode = 1/8" arc length etc. The thicker the electrode coating the shorter the distance from the end of the electrode to the work. Drag rods are contact rods. E-7024 is one.

Arc length is the distance from the tip of the electrode to the workpiece.

Arc length is the maximum length between the tip of an electrode and the work, measured along the tangents.
2*pi*r
Depend upon dia of electrode & Arc length between Electrode tip and job surface.
The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
Arc length, current (amperage,) travel speed, work angle, travel angle.
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
Yes, arc welding does create ozone. It is because the temperatures created during arc welding convert the nearby oxygen to ozone.
smaw welding is sheilded metal arc welding
