Material type and ideal thickness
- Carbon steel only
- Best cuts from gauge to 152 mm (6”) or more, quality cuts from 6 mm (1/4”) through 51 mm (2”)
Cut quality
- Good, provided the operator is skilled and can hold the correct standoff
- Large heat-affected zone common because of slow cut speeds
- Edges typically are rough; however with a skilled operator, edges can be as clean as plasma and with better angularity
- Dross removal required, unless the operator is very skilled
Productivity
- Process is slower than plasma when cutting thinner (less than 3/4”) material
- Preheating is required at the cut starting point
Operating cost
- High due to high cost of gas, cylinder rental fees, and low cut speed
- Operating cost becomes more competitive with plasma when cutting thicker material
- Low service and maintenance requirements
Capital equipment cost
- Medium, more than a hand tool, less than plasma
- Good quality torch and fuel cylinders: $350 (hobbyist grade) to $1,000 (commercial grade)
Portability
- Medium portability
- Not dependent on a primary power source, but fuel and oxygen canisters are required
Bottom line
Consider oxyfuel if you need to cut carbon steel 152 mm (2”) or more in thickness.
