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. 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.
