without dross. Although less than optimal cuts will
contain dross, it is relatively easy to remove by break-
ing it off using pliers or chipping off with a chisel or
scraping or grinding the finished cut as needed and
is generally only a minor inconvenience.
A combination of factors contributes to the build-up
of dross. They include; material type, material thick-
ness , amperage used for the cut, speed of the torch
across the work-piece, condition of the torch tip, in-
put line voltage, air pressure, etc. Generally there is an
inversely proportional relationship between output
current and speed of cut. Do not use more output
current than is necessary and adjust speed of cut
toward minimizing dross build-up on underside of
cut. Experiment with adjusting current and speed to
minimize dross.
When dross is present on carbon steel, it is common-
ly referred to as either ‘high speed, slow speed, or top
dross’. Dross present on top of the plate is normally
caused by too great a torch to plate distance.
‘Top dross’ is normally very easy to remove and can
often be wiped off with a welding glove. ‘Slow speed
dross’ is normally present on the bottom edge of the
plate. It can vary from a light to heavy bead, but does
not adhere tightly to the cut edge, and can be easily
scraped off. ‘High speed dross’ usually forms a narrow
bead along the bottom of the cut edge and is very
difficult to remove. When cutting troublesome steel,
it is sometimes useful to reduce the cutting speed to
produce ‘slow speed dross’. Any resultant clean up
can be accomplished by scraping, not grinding.
