The
shape
of
the
electrode
for DC
welding has
to
be
and
remain
as sharp as a pencil. The
angle
of
the
point
depends
on
the
welding
current.
When
AC welding,
ii
is
sufficient
to
sharpen
the
edge
of the electrode
slightly.
After
a
short
time,
a
round to
slightly convex form
is
built.
If
the
electrode tip
is polluted due to dipping
into the weld
pool
or
touching
the filler
wire,
the
respective
part of the
electrode
must
be completely
ground
off.
Restore
the
original, pointed shape.
Grind
in longitudinal
direction.
