11.4 Travel Angle
The travel angle is the right to left, relative to the direction of welding. A travel angle of 5°- 15° is ideal and produces the
right level of control over the weld pool. A travel angle higher than 20° will give an unstable arc condition with poor weld
metal transfer, less penetration, high levels of spatter, weak gas shielding and a poor quality finished weld.
11.5 Work Angle
The work angle is the up and down angle of the gun relative to the workpiece.
The correct work angle provides good bead shape, prevents undercut, uneven penetration, weak gas shielding and a
poor quality finished weld.
11.6 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 a stick out will cause an unstable weld pool, produce spatter and overheat the contact tip. Too long
stick out will cause an unstable arc, lack of penetration, lack of fusion, and increase spatter.
