The SETUP submenu

The

SETUP

menu choice allows laser system reconfiguration. Selecting this option will lead to other

menu choices.

Then

TICKLE

is the term used for small pulses which are fed to the laser to keep the plasma inside

energized. This allows the laser to respond quickly for high speed cutting and engraving. The tickle is
preset at the factory and usually will not require adjusting. However as the laser ages it may become
necessary to change these settings to maintain peak performance.

WARNING:

Do not attempt to adjust the

TICKLE

setting. Consult the ULS technical staff first to

determine whether it is necessary.
