2.5 Gas Jet Tip Centering
The best cutting quality to a great extent relies on the centering lens. If the lens is not in the middle, the beam may
touch the tip or the inner wall and lead to deformation because of high temperature.
When the gas jet tip is changed or the cutting quality is not good, the lenses should be centered.
Tip centering of BT210 is accomplished by adjusting the X-Y position of the collimating lenses.
2.5.1 QCS Beam Centering
There are four set screws in the four corners. Divide them into two groups and each group has two screws.
Set the screws in pair: tighten one and loosen the other.
Centering method：
Loosen the adjuster screw in the opposite direction you want the beam to move. Then tighten the adjuster
screw that is opposite of the screw that is opposite of the screw that was just loosened.
Use two groups of screws until the beam is centered in the tip.
