Of current or output wattage?
@ednisley is correct, do adjust your lps for the maximum value you desire.
There are two trains of thought here…
I prefer to adjust for maximum current, as I think of it in mA…
If you don’t know, like the rest of us do, the maximum current probably doesn’t directly relate to maximum watts out.
If you wish to base your percentages on power, you have to find where the output is the greatest and use that mA value as a maximum…
If you go through the percentages with a wattmeter or use a piece of acrylic, you can see the power curve, close to a line, which isn’t too bad of a linear shape.
My whole time with co2, I’ve used percentage of current, not watts out. I think the watts out will be better and that’s how my current machine is setup. This usually occurs below the rated current, so it also helps with limiting current to the tube.
Maybe @ednisley has one of pieces of acrylic or a graph he did.
The Ruida has a field for setting the pwm lower/upper limits. It’s in the last field of the vendor settings.
I read this as a working currrent of 24mA and a maximum of 28mA…?
Good luck
