Table 4-B Cut Quality on Various Materials and Material Thicknesses
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 removed), 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.
Cut quality depends heavily on set-up and parameters such as
torch standoff, alignment with the workpiece, cutting speed, gas
pressures, and operator ability.
