What am I doing wrong please!!
I need to cut some relatively thin sheet (2mm) mild steel using an
oxy-acetylene straight line cutting machine (BOC PUG). I know really the
sheet is a bit thin for this. I'm using the smallest cutting nozzle I can
find (1/32"), with 5 psi Acetylene and 20 psi Oxygen.
As the cut proceeds it fills back in and re-welds behind the cut. I've tried
speeding up to the point that the pre-heat isn't enough and the cut stops,
and slowed down to the point that the kerf is too wide. I've raised the
nozzle, and lowered the nozzle. I've raised the oxygen pressure to 30 psi
and lowered it to 10 psi bit still I get a nice straight line of weak
I don't want to have to go back to the jig saw - HELP !!!!
