Cut quality problems
The following are problems that you can have when the appearance of a cut is not satisfactory:
Cut angle (bevel)
– The degree of angularity of the cut edge.
Dross
– The molten material that becomes solid on the top or bottom of the workpiece.
Each is explained in the following sections.
Cut angle (bevel)
The squarest cut angle is always on the right side with respect to the
forward motion of the torch. The left side always has some degree of
bevel. A bevel angle of more than 5 degrees shows a possible problem.
Cut angle (bevel)
Causes
Solution
Negative bevel
More material is removed
from the bottom of the cut
than from the top.
• The cutting speed is too slow.
• The torch 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.).
• Decrease the amperage in 10 A
increments.
No bevel (square cut)
This is good cut quality.
Positive bevel
More material is removed
from the top of the cut than
from the bottom.
• The cartridge is worn.
• The cutting speed is too fast.
• The torch 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.).
• Increase the amperage in 10 A
increments.
Irregular bevel
Positive and negative bevel
on the same workpiece.
• The cartridge is severely worn.
• The torch is not aligned
perpendicular to the workpiece.
• Cut surface is concave on one
side and convex on the other side.
• Install a new cartridge.
