I purchased a Hypetherm. I was lead to beleive that the consumables
would be less exspensive and they would last longer than the
competetion machines. This proved not to be true. The consumables are
very exspensive and they have a short life span. It is cheaper to use
oxy- acetelyne. I would buy one only if I needed it for cutting non
ferrous materials.

How dry is your air? Or do you use nitrogen? I don't like torch
cutting because of the surface it leaves. Plasma is so much cleaner
and so requires much less time cleaning it up. I have had some pieces
plasma cut for me and the cut edges were beautiful. Not so for torch
cut parts. Especially if I'm the one doing the cutting!

I have a Cutmaster 75 (Thermal Dynamics?) and put a dessicant filter on
it right at the back of the machine. After a full year of cutting around
the farm and building an automatic firewood processor with it, I think
I've gone through two or three tips and nozzles. Use very dry air and
avoid using more amperage than you need and plasma cutting is
super-cheap. The newer machines seem to get MUCH more milage out of
consumables so don't bother with a used machine.
