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.
[3] 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.
[4] Stick Out
Stick out is the length of the unmelted wire protruding from the end of the contact tip. A constant even stick
out of 5-10mm will produce a stable arc, and an even current flow providing 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 penetration, lack of fusion and increase spatter.
