making very fine cuts with the 40AMP/50AMP torch

[performance]

Its hard on cons, but to etch, just don't use the ground clamp and the torch will not cut.

Without the ground clamp the torch does not do what I am calling etching.

Anyway, I ordered some .6mm nozzles. I am told that they are rated at 5 to 15 amps. What will happen if I go over the rated amps? Will I break something???

Where did you order them from?

Keep in mind, the units minimum amps is 20.
What it will do is blow the bottom out of the consumable, or at least widen the hole.

Since I have no idea what I am doing,, I probably got too small of nozzles. I will turn it down to 20 and hope that is not too much more than 15 amps. As long as it does not screw up my torch it will not get too upset if it burns the hole in the .6 nozzles. Oh well they were only $14 with shipping on Ebay. That is the only place I could find them.

As Ray mentions, consistency is all important. This cut was done with a constant feed, no wavering and it turned out pretty nice.
