Probable Cause
Dross and cut surface:
Varying characteristics
of material being cut.

Incorrect standoff
Incorrect cut gas or shield
gas flow.
Incorrect alignment or
improper operation of
air curtain or bubble
muffler.
Damaged or worn
consumables.
Using non-genuine
consumable part.
Gas selection.
Torch alignment to work.

Adjust to correct speed.
Refer to Subsections 4.3 and 4.5 for applicable
cutting techniques.
Refer to Subsections 4.1 and 4.2.

Verify and correct torch alignment.
Verify correct current. Refer to appropriate cut-
ting tables after Subsection 4.4.
Cutting over slats will cause some bottom dross.
If the cut runs along the slat, it can produce other
cut quality problems. The only solution is to try
to avoid running along the slats.
Make sure brackets and height control are rigid
and properly adjusted.
Check to be sure swirl is in the same direction.
Remove swirl parts that are marked with an "R".
Same as dross and cut surface above
except varying characteristics of material being
cut and cutting machine or torch vibrations.
Standoff and speed have considerable effect
on bevel angle.
