The back-sweep option blows an air jet toward the back of the machine..
The angle and height of the air jet can be independently adjusted. A flexible air tube is attached to an air outlet arm that can be rotated and locked in position to set the angle. The arm is attached to a bracket that can be adjusted up or down to match the focus point.
As we would expect from ULS engineering, this option has been well designed for precision, ease of use, and effectiveness! Combining this option with a nozzle cone and adjustable pressure lets the customer use air to the best advantage according to the type of application.
CHOICE OF OUTPUT AND PRINT DRIVER:
The XP/2000 print driver has an option for front-to-back engraving.
Front-to-back engraving with the back-sweep works well on rubber stamps or other dusty applications. It helps keep the material clean and also keeps the machine cleaner.
For cutting applications the nozzle is superior. The nozzle is also superior for heavy engraving on highly flammable materials because the downward air jet protects the focus lens from flame damage.
Purpose:
To blow high pressure air at the point of laser interaction with the material to be cut or engraved.
Advantage:
High PSI (pressure) design with user-adjustable pressure regulator can be configured for many applications. Back sweep design reduces flaming and cools material as well as directs smoke and fumes toward the exhaust, thus keeping engraving and cutting materials cleaner.
