CO2 Laser: Help with older ULS model
 

Hi people,

I need some help understanding and using the controls of an old (1992)
Universal Laser Systems CO2 marking and engraving laser.

It has 3 main control panels.

1. Program set up and selection
Here you can set Pulse Width and Pulse Rate
I am having trouble understanding the relationship between the two.
I cannot save changes. It has 10 preset programs so I assume they can
be saved somehow

2. Speed
Pressing the buttons 1 through 8 does not seem to affect anything.

3. Function
The Pause button works but I cannot seem to get any of the other
options to do anything. Things like "Repeat" does not repeat.

I am hoping there might be another old timer out there who messed with
these early models and can shed some light.

Dave
