WELDING POSITIONS
There are three basic welding positions:
flat, horizontal, and vertical.
.
The FLAT POSITION (Figure 12) is
the easiest of the welding positions
and is probably the one you have
been using thus far. It is best if you
can weld in the flat position if at all
possible as good results are easier
to achieve.
.

The HORIZONTAL POSITION
(Figure 13) is next in difficulty level.
It is performed very much the same
as the flat weld except that angle B
(see POSITION OF THE GUN TO
THE WORK PIECE, above) is such
that the wire, and therefore the arc
force, is directed more toward the
metal above the weld joint. This is
to help prevent the weld puddle
from running downward while still
allowing slow enough travel speed
to achieve good penetration. A good
starting point for angle B is about
30 degrees DOWN from being
perpendicular to the work piece.

.
The VERTICAL POSITION (Figure
14) is the next most difficult
position. Pulling the gun from top to
bottom may be easier for many
people, but in some instances it can
be difficult to prevent the puddle
from running downward. Pushing
the gun from bottom to top may
provide better puddle control and
allow slower rates of travel speed to
achieve deeper penetration. When
vertical welding, angle B (see
POSITION OF GUN TO THE
WORK PIECE, above) is usually
always kept at zero, but angle A will
generally range from 45 to 60
degrees to provide better puddle
control.
