relation to the weld puddle. The gun is either
PUSHED (see Figure 11) into the weld pud-
dle or PULLED away from the weld puddle.

Figure 11. Travel Direction
For most welding jobs you will pull the
gun along the weld joint to take advan- -
tage of the greater weld puddle visibility.
2. TRAVEL
SPEED is the rate at which the
gun is being pushed or pulled along the
weld joint. For a fixed heat setting,
the
faster the travel speed, the lower the
penetration
and the lower and narrower
the finished
weld bead. Likewise,
the
slower the travel speed, the deeper the
penetration
and the higher and wider the
finished
weld bead.
TYPES
OF WELD
BEADS
The following
paragrap_hs discuss
the most
commonly
used weldin_]'beads.
Once you have the gun in position
with the
wire lined up on the weld joint, lower your
helmet,
pull the trigger and the arc will start.
In a second
or two you will notice a weld
puddle form and the base of the bead be
ginning to build. It is now time to begin to
move with the gun. If you are just learning to
weld, simply move the gun in a straight line
and at a steady speed along the weld joint.
Try to achieve
a weld with the desired
penetration
and a bead that is fairly flat and
consistent
in width.
As you become
more familiar with your new
welder and better at laying some simple weld
beads, you can begin to try some different
weld bead types.
There are two basic types of weld beads, the
stringer
bead and the weave bead.
1. The STRINGER BEAD (Figure 12) is
formed by traveling with the gun in a straight
line while keeping the wire and nozzle
18
centered
over the weld joint. This is the easi-
est type of bead to make.

2. The WEAVE
BEAD (Figure 13) is used
when you want to deposit metal over a wider
space than would be possible with a stringer
bead. It is made by weaving
from side to
side while moving with the gun. It is best to
hesitate
momentarily
at each side before
weaving
back the other way.

WELDING
POSITIONS
There are four basic welding
positions:
flat,
horizontal,
vertical,
and overhead.
1. The FLAT POSITION
(Figure 14) is the
easiest of the welding
positions
and is most
commonly
used. It is best if you can weld in
the flat position
if at all possible as good
results are easier to achieve.

2. The HORIZONTAL
POSITION
(Figure 15)
is next in difficulty
level. It is performed
very
much the same as the flat weld except that
