Hilbertk,

Good to see you again.  Good questions.

ESAB and Komatsu make torches for plasma cutting that have nothing to do with our torches: not the same type of technology (transferred arc vs. non transferred arc, much lower power than our torches.)

In my opinion they would have significant barriers to entry: they would need to develop technology development from scratch and they would need to obtain a license from us as our patent has pretty much prevented anyone from using torches in induration furnaces.

I am not concerned about them.

Of course, we do not rest on our laurels, and as such our goal is to leverage our first mover advantage into market share and increasing competitive advantage through continuous improvement (and of course: cross selling)

Hope that helps,

Peter
