Description of Cut Characteristics

Excellent

- Minimum bevel (0 - 4°), minimum kerf (2 x

tip orifice diameter), little or no dross, smooth
cut surface.

Good

- Slight bevel (0 - 10°), slightly wider kerf (2-1/2 x

tip orifice diameter), some dross (easily re-
moved), medium-smooth cut surface, slight top
edge rounding.

Fair

- Excessive bevel (over 10°), wide kerf (over 2-1/2 x

tip orifice diameter), medium to heavy dross, rough
cut surface, top edge rounding.

NOTES

Cut quality depends heavily on set-up and param-
eters such as torch standoff, alignment with the
workpiece, cutting speed, gas pressures, and op-
erator ability.
