Dross
Dross (slag) is molten metal that is the result of the cut process and that hardens on the bottom of
the part. There is always some amount of dross when cutting with plasma. To keep the amount and
type of dross to a minimum, adjust your system correctly for your application.
Problem Causes Solution
Too much dross (splatter) on the
top of the plate. • The cartridge is worn.
• The cutting speed is too fast.
• The torch is too high. Or, if you
are using a torch height
control, arc voltage is too high.
• Install a new cartridge.
• Decrease the cutting speed in
small increments
(125 mm/min or 5 in/min or
less).
• Lower the torch in small
increments (2 mm or 1/16 in.).
Or, if you are using a torch
height control, decrease the
arc voltage in small increments
(5 volts or less).
Low-speed dross that collects on
the bottom of the cut and is heavy
and bubbly. • The cutting speed is too slow.
• The torch is too low. Or, if you
are using a torch height
control, arc voltage is too low.
• The amperage is too high.
• Increase the cutting speed in
small increments
(125 mm/min or 5 in/min or
less).
• Lift the torch in small
increments (2 mm or 1/16 in.).
Or, if you are using a torch
height control, increase the
arc voltage in small increments
(5 volts or less).
• Decrease the amperage in
10 A increments.
High-speed dross near the cut that
is a thin, linear bead of solid metal.
It is welded to the bottom of the
cut and is difficult to remove. • The cartridge is worn.
• The cutting speed is too fast.
• The torch is too high. Or, if you
are using a torch height
control, arc voltage is too high.
• The amperage is too low.
• Install a new cartridge.
• Decrease the cutting speed in
small increments
(125 mm/min or 5 in/min or
less).
• Lower the torch in small
increments (2 mm or 1/16 in.).
Or, if you are using a torch
height control, decrease the
arc voltage in small increments
(5 volts or less).
• Increase the amperage in 10 A
increments.
