5.3. Hold the torch in one hand, allowing the nozzle to rest on the edge of the work piece
farthest away from you, and at an angle similar to that which will be used when welding.
(See HOLDING THE TORCH if you are uncertain of the angle at which you will be welding).
5.4. With your free hand, turn the Wire Speed Dial to maximum and connue to hold
onto the knob.
5.5. Lower your welding helmet and pull the trigger on the torch to start an arc, then
begin to drag the torch toward you while simultaneously turning the Wire Speed Dial
counter-clockwise.
5.6. LISTEN! As you decrease the wire speed, the sound that the arc makes will change
from a spuering to a high-pitched buzzing sound and then will begin spuering again if
you decrease the wire speed too much. The point on the wire speed adjustment where
the high-pitched buzzing sound is achieved is the correct seng. You can use the wire
speed control to slightly increase or decrease the heat and penetraon for a given heat
seng by selecng higher or lower wire speed sengs. Repeat this tune-in procedure
if you select a new heat seng, a dierent diameter wire, or a dierent type of welding
wire.
6. Welding Techniques
WARNING:
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 unl you are adequately protected. Wear ameproof welding gloves, a
heavy long sleeved shirt, trousers with out cus, 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.
6.1 Moving the torch
Torch travel refers to the movement of the torch along the weld joint and is broken into
two elements: Direcon 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 erracally will prevent proper fusion or create a lumpy, uneven bead.
Travel direcon is the direcon the torch is moved along the weld joint in relaon 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 advantage of the
greater weld puddle visibility.
