positioned horizontally, vertically and overhead as shown in Figure 3.8, 3.9, and 3.10 respectivily. It must be realized at the
very beginning that welding in these positions is difficult and will require constant practice to develop skill. Generally, under
these conditions it is helpful to reduce the current from the value used on welding in the flat position.

STRIKING THE ARC-RUNNING BEADS
In learning to weld there are certain fundamental steps which must be mastered before one can attempt to weld on actual
work. Prior to striking an arc, insert the electrode in the holder, as shown in Figure 3.11. To strike an arc, Figure 3.12 illustrates
what is commonly known as the scratch start technique. In this method the striking end of the electrode is dragged across
the work in a manner much the same as striking a match.
