achieved is the correct setting. You can use the wire speed control to slight-
ly increase or decrease the heat and penetration for a given heat setting by
selecting higher or lower wire speed settings. Repeat this tune-in procedure
if you select a new heat setting, a different diameter wire, or a different type
of welding wire.
Welding Techniques
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES
AND SKIN! Prolonged exposure to the welding arc can cause blindness and
burns. Never strike an arc or begin welding until you are adequately protec-
ted. Wear flameproof welding gloves, a heavy long sleeved shirt, trousers with
out cuffs, high topped shoes and an ANSI approved welding helmet.
ELECTRIC SHOCK CAN KILL! To prevent ELECTRIC SHOCK, do not perform
any welding while standing, kneeling, or lying directly on the grounded work.
Moving the torch
Torch travel refers to the movement of the torch along the weld joint and is
broken into two elements: Direction and Speed. A solid weld bead requires
that the welding torch be moved steadily and at the right speed along the
weld joint. Moving the torch too fast, too slow, or erratically will prevent pro-
per fusion or create a lumpy, uneven bead.
Travel direction is the direction the torch is moved along the weld joint in
relation to the weld puddle. The torch is either PUSHED into the weld puddle
or PULLED away from the weld puddle.
For most welding jobs you will pull the torch along the weld joint to take ad-
vantage of the greater weld puddle visibility. Travel speed is the rate at which
the torch is being pushed or pulled along the weld joint. For a fixed heat set-
ting, 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 welding beads
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.
The STRINGER BEAD Is formed by traveling with the torch in a straight line
while keeping the wire and nozzle centered over the weld joint (See following
figure)
