may be considered as the maximum, which can be used
without burning through the work, over-heating the electrode
or producing a rough spattered surface. The table shows
current ranges generally recommended for a general purpose
type 6013 electrode (see Table 1).

ARC LENGTH

To strike the arc, the electrode should be gently scraped on the
work until the arc is established. There is a simple rule for the
proper arc length; it should be the shortest arc that gives a
good surface to the weld. An arc too long reduces penetration,
produces spatter and gives a rough surface finish to the weld.
An excessively short arc will cause sticking of the electrode and
result in poor quality welds. General rule of thumb for down
hand welding is to have an arc length no greater than the
diameter of the core wire.
ELECTRODE ANGLE
The angle that the electrode makes with the work is important to
ensure a smooth, even transfer of metal. When welding in down
hand, fillet, horizontal or overhead the angle of the electrode is
generally between 5 and 15 degrees towards the direction of
travel. When vertical up welding the angle of the electrode should
be between 80 and 90 degrees to the workpiece.

TRAVEL SPEED

The electrode should be moved along in the direction of the
joint being welded at a speed that will give the size of run
required. At the same time, the electrode is fed downwards to
