Angle A
Welding techniques:
Types of welding beads:
• Angle A can be varied, but in most
cases the optimum angle will be 60
degrees (the point at which the torch
handle is parallel to the workpiece).
If angle A is increased, penetration
will increase; if it is decreased,
penetration will decrease (fig. G).
• Angle B can be varied to improve the
visibility of the arc in relation to the weld
puddle and to direct the force of the arc
(fig. H).
6. When the wire speed decreases, the sound that the arc makes will change from a sputtering
sound to a high-pitched buzzing sound. The correct setting is the point where the high-pitched
buzzing sound is achieved.
Use the wire feed control to slightly increase or decrease the heat and penetration by
selecting higher or lower wire feed settings. Repeat this tune-in procedure if a new heat
setting, a different diameter wire, or a different type of welding wire is selected.
• Torch travel: The movement of the torch along the weld joint. For a solid weld bead, the
welding torch should be moved steadily and at the right speed along the weld joint. Moving
the torch too fast, too slow, or erratically prevents proper fusion or creates a lumpy, uneven
bead.
• Travel direction: The direction of the torch moving 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, pull the torch along the weld joint for greater weld puddle visibility
(fig. J).
• Travel speed: The rate at which the torch is being pushed or pulled along the weld joint. For a
fixed heat setting, if the travel speed is faster, the penetration will be low and the finished
weld bead will be low and narrow. Likewise, if the travel speed is slow, the penetration will be
deep and the finished weld bead will be high and wide.
• The stringer bead is formed by
travelling with the torch in a straight
line while keeping the wire and nozzle
centred over the weld joint (fig. K).
• The weave bead is made by weaving the
wire from side to side while moving with
the torch (fig. L).
4. Turn the wire speed dial with the other hand to its maximum position and continue to hold
onto the knob.
5. Pull the trigger (1) on the torch to start an arc. Drag the torch toward the user while
simultaneously turning the wire speed dial counter-clockwise (fig. I).

WARNING!
• Prolonged exposure to the welding arc can cause blindness and burns.
• Do not perform any welding while standing, kneeling, or lying on the grounded
area. Failure to comply could result in serious injury or loss of life.
Potential hazard that could result in serious injury or loss of life.
