Cutting SSteel .75 (14ga) problem
(OP)
Help I'm using AMADA 1212a3 it just started today when I am cutting 14ga
SS the cut is golden color before was clear looks like burn and I am getting small dross on all edges. Using N2 as assist. Changed lens nozzle didn't change cutting parameters. Why I'm getting that color and burn???

If possible, do the same with the air supply.

A fairly easy way to check if you do have oxygen leaking out through the nitrogen line would be to disconnect your nitrogen line. Then run an oxygen test. While running the test, either check by the disconnected nitrogen line if you "feel" gas coming out. If it's very low pressure and volume, it may be hard to "feel". In that case, you could connect the gas line to a bucket of water and check for bubbles.

The gas company near me is a little crazy, they sell a kit to put handlebars, fins, a seat and nosecone on a high pressure gas bottle. Liftoff is via hammer to valve....... Where's my crash helmet?

Did you mean from cylinders?
Pressure in in the output lines is correct according to AMADA settings.

That being said, if you still want to check that the machine gas system is OK (basically to check that the non-return valves are doing their job), you can do the bubble test mentioned earlier.

i think the problem with the golden colour is the proportional valve on your machine, some leakage between oxygen and nitrogen inside the valve,even a small leakage from oxygen will kontaminate the stainless .
