We will probably never know which one is the correct explanation
What I've understood is that
Arc Length will change during the entire process
Cutting 1mm sheet will start from 0 to 1mm+electrode to work distance
Cutting 20mm will start from 0 to 20mm+electrode to work distance
And I think it might be right , but I can't say that for sure
Can't waitI have just ordered an AC/DC clamp meter which should be with me towards the end of the week.
That will allow me to do some tests on different thicknesses and with consumables of different states of newness. It will be interesting to see the results and maybe I will find out my Plasma is on its way out
@Munkul
I hope you are not misunderstanding my words
I certainly would not want to cause bad feelings among us
because I would like to better understand how this type of machine works.
I cannot understand how the arc length would be always the same as the arc is generated between workpiece and the electrode into the torch
What I cannot explain is that I think (I don't know if it's right ) that while performing cutting the plasma start cutting from the upper part of the workpiece to the lower oneThe current flows between workpiece and torch, but the arc is almost a seperate entity, because of the swirl of gas flow. The arc just needs to contact the workpeice, it is NOT a welding type arc in any shape or form
