we recently got our K40 in our association (+C3PB e.V.
) and have a very basically question.
We have the "analog" model with the analog amperemeter and we are not sure what's the normal operation current for the 40W laser tube - as normal I would declare, what's 100% for the digital model.
The very "interestingly" translated user manual says max. 6mA, the specs sheet says about max 20mA. On the internet I found various numbers between 4mA to 26mA.
So what are your experiences? Till now we didn't dare to use more than 6mA and the cutting of 4mm plywood was quite okay at 6mm/s. So would even more be possible with higher current? Or maybe someone with the digital model and the proper tools can measure which current it delivers to the tube at 100%?!
Thanks a lot in advice! :-)
