Basics
What is plasma, why does it cut
What can be cut
Inspecting compressor and cut-50
Fitting consumables (examine, check, what constitutes too much wear, show examples)
Connecting up the equipment (air cleanliness & water)
Torch safety (airflow/electrical)
Starting up
Compressor
Setting pressure (3-6 bar)
CUT-50
Setting current (10A+5A/mm)
Cutting
Basic how-to
Preparing material (consider contaminants, good ground contact, consider what’s underneath and on the underside)
Torch perpendicular and slow even movement
OK to brace on the material
How to recognise problems
Demo on thin sheet
Practice on thin sheet
Piercing
Guides (metal and wood, the differences)
Proper settings and how to choose them
Cutting on thicker materials
Cutting speed/spark angle (15-20 deg)
Flick-finishing
Piercing
Descaling
Demo & Practice
Other topics
Piercing into enclosed spaces
