I have been getting used to my ArcDroid, prior to the cable to my plasma cutter arriving. The question I have is, is there a way to have ArcDroid briefly trigger the plasma to create a small divot in the material, marking it to be drilled in a later operation?. I understand that this will not be overly accurate, but that is like most of my work!
Thank you.
If by small hole then yes, it is called a pierce, but it will be all the way through and no smaller than the width of a plasma cut, and technically probably larger since it is blowing through in one spot. I suppose you could turn down the air pressure and the amperage on your plasma cutter but the arcdroid has no feature to automagicalaly ramp it all back up so you would need to run 2 separate files for the low amp pierce and then second for the cuts. I imagine if you really wanted you could adapt a marker to your arcdroid and have it trace out and leave a mark in the spot you need it marked. It would be cheaper than ruining consumables doing low amp stuff that will probably cause more harm to them. The difference between a plotter and a plasma cutter is nominal so long as you are not using torch height as a factor
Keep in mind when air plasma touches steel it gets nitrided and super hard.
Its nearly impossible to drill thru
Not sure if it starts instantly, or if it takes half a second to get hot enough to nitride.
Let us know how it works
Try using a step drill I’ve had good luck drilling out cut pilot holes
