Connection
How we hook it up
The CNC port provides trigger and divided arc voltage.
- 01
Clamp the ArcDroid to the table and plug in its power supply.
- 02
Connect the cutter's CNC output to the ArcDroid controller.
- 03
Fit your torch in the universal holder and tighten both clamps.
- 04
Run the guided calibration on screen: height probing, arc-start test, arc-voltage setting.
- 05
Trace or import your first part. Cut.
In practice
Cutting with a Thermacut on the ArcDroid
What the ArcDroid controls
Through your Thermacut's CNC output, the ArcDroid fires the arc and reads the divided arc voltage: the torch height adjusts itself during the cut, even on a slightly warped sheet.
Starting settings
Set the amperage on the Thermacut for the thickness, as you would for hand cutting. Speed, pierce height and cut height are set on the ArcDroid's screen, with no computer. Our reference values by thickness and amperage are in the guide.

Three checks are enough: the exact model reference of your Thermacut, the start type (pilot arc or contact, never HF) and where the CNC output is. In doubt? Send us a photo of the rating plate.

Thermacut and ArcDroid
Which EX-TRAFIRE model for a workshop?
The 45SD covers steel up to about 12 mm, the 75SD goes to 20 mm. We check the start type of your version before ordering.
Does automatic torch height control work with a Thermacut?
Yes: the Thermacut's CNC output supplies the divided arc voltage the ArcDroid uses to adjust the torch height during the cut.
Can I keep my Thermacut hand torch?
Yes. The hand torch mounts in the ArcDroid's universal holder with no modification: two clamps to tighten, and you have it back in your hand just as quickly for hand cutting.
Unsure about your version?
