After visiting one of the sci.engr.joining.welding posters today (thanks Rob!) I have a much clearer idea of what is plasma cutting. For example, I realized that a jet of plasma should be coming out of the head even at a distance from the "work" (from the pilot arc).
Now, I have a question regarding my mystery plasma torch.
Here it is:
In any case, my main question centers around two compression fittings. One is electrically connected to the tip, another to the nozzle.
Can I use this torch by supplying compressed air to BOTH of these fittings (I realize that one is connected to the tip and another to the nozzle, to make a pilot arc, so proper electrical isolation etc will be necessary).
Or is this torch supposed to be used with two different gases?
All I want for now is to make a small pilot arc, that would be a good first step.
thanks
