Oxy fuel Advantages

Thick mild steel cutting on greater than 75 mm (3 in.)

Between 50 mm (2 in.) and 75 mm (3 in.), it depends on volume to determine when to use oxyfuel or plasma

Plasma Advantages

Better cut quality than oxyfuel

Higher productivity than oxyfuel due to faster cutting speeds; better than CO₂ and fiber on materials less than 1/4 in. (6 mm)

Lower cost per length of cut than oxyfuel; lower operating cost than laser on materials thicker than 1/4 in. (6 mm)

Increased flexibility over oxyfuel, fiber laser, or CO₂ laser with the ability to cut a wide range of material thicknesses and metal types

Significantly lower capital, operating, and maintenance costs than CO₂ laser

Between 6 mm (1/4 in.) and 20 mm (3/4 in.), it depends on volume and amount of fine-feature cutting to determine when to use plasma or fiber/CO₂ laser

Fiber Laser Advantages

Excellent cut quality and productivity on material less than 6 mm (1/4 in.)

Better cut quality than plasma for fine features

Better cut quality than plasma on holes, with the ability to produce holes less than a 1:1 diameter-to-thickness ratio

Lower operating and maintenance costs compared to CO₂ laser and plasma

Between 6 mm (1/4 in.) and 20 mm (3/4 in.), it depends on volume and amount of fine-feature cutting to determine when to use plasma or fiber/CO₂ laser

CO₂ Laser Advantages

Excellent cut quality and productivity on material less than 6 mm (1/4 in.)

Better cut quality than plasma for fine features

Better cut quality than plasma on holes with less than a 1:1 diameter-to-thickness ratio

Higher powers enable cutting a broad thickness range with good tolerance
