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
