If it's Oxy/Accet

1/16" cutting nozel
10 Psi Accet / 28 Psi Oxy ( Approx )

On 5mm plate you'll need quite a fast speed of travel when you are cutting .... Too slow & you'll get a build up of dross just as you describe

It is very important that the cutting nozel is clean, especialy the centre Oxy hole.

When you have marked the part to be cut out, it will help if you use a centre punch to mark the lines ( Every 10mm or so & closer on the curved parts )

Once you get the knack of cutting a reasonable line, it does not take long to fettle the part with a flap disc
