Travel Angle - Travel angle is the right to left angle relative to the direction of welding. A travel
angle of 5°- 15° is ideal and produces a good level of control over the weld pool. A travel angle
greater that 20° will give an unstable arc condition with poor weld metal transfer, less penetration,
high levels of spatter, poor gas shield and poor quality finished weld.

Angle to Work - The work angle is the forward back angle of the gun relative to the work piece.
The correct work angle provides good bead shape, prevents undercut, uneven penetration, poor
gas shield and poor quality finished weld.

Stick Out- Stick out is the length of the unmelted wire protruding from the end of the contact tip.

good penetration and even fusion. Too short stick out will cause an unstable weld pool, produce
spatter and over heat the contact tip. Too long stick out will cause an unstable arc, lack of pen-
etration, lack of fusion and increase spatter.
