The length of the arc depends upon the type of electrode and the type of welding being done; therefore, for
smaller diameter electrodes, a shorter arc is necessary than for larger electrodes. Remember: the length of the
arc should be about equal to the diameter of the bare electrode except when welding in the vertical or over- head
position. In either position, a shorter arc is desirable because it gives better control of the molten puddle and
prevents atmospherical impurities from entering the weld.
