Hi! "some" time has passed so I would like to ask how did the Stahlwerk Cut 100 work out as a CNC plasma cutter power source?

Kind regards/Stefan

I never got it, living in this country is going from shitty to extremely tough, the power just got a price hike of exactly 242 % !
I friend had a CUT 70 from StahlWerk and it worked perfectly well, granted does not like having the torch to far from material when firing, 3 to 4mm are ok, at 5 it occasionally fails to start.
Now i am trying to get a Kzubr (some Russian Chinese abomination) and i was told they have one here for 600E, it says 100A but i would bet my life it will not do over 50 or 60, but i am ready to be amazed !
Do remind me in a week or two.
BTW the 70A Stamos (or similar) that he bought instead of StahlWerk also works fine, been something like 4 months without issues.

Does not look like pilot start, there is a missing connection for a usually red thinner wire.
More pictures?

As far as i can tell, there is no pilot arc there, at least not the conventional ones.
Do a test and fire the torch in mid air, does it spark? Meaning without touching material or clamp.
If not, it is a scratch start so requires dragging the torch on the material to start, and if this is the case, not suitable for CNC use.
There might still be an option but it would require programing a component and testing on an actual machine. The component would have to intervene after the torch went down and found the material then do a short wiggle/circle while going up to pierce height, and also the firing of the torch should be done when the material is detected, so before the usual start at pierce height.

Stahlwerk, Stamos, even my Kzubr is still working just fine, although mine has been siting idle for nearly 2 months, the rest are in use daily.
Stahlwerk has it's own website, and stuff there is cheaper that on Amazon
Vertical machine torch is from 40-50 usually

70A with pilot arc is 450 but currently not available

Here is the full list of plasma, mind the pilot arc and notice those with pilot arc have another red connector on the lower front.
