| Plasma torch nozzle is worn. | The most common cause for increased edge angularity is a worn nozzle. Remove your plasma torch from the torch mount and inspect the nozzle orifice for wear. Replace as necessary. |
| Moisture in the compressed supply air. | Moisture in the supply air can result in decreased cut quality which can produce undesired edge bevel. Make sure that you have a water separator in line with your supply air going to the plasma cutter. Also ensure that this water separator is functioning properly and is not full. |
| Torch is not perpendicular to cut surface. | Inspect that your torch is mounted properly in the torch mount and that the torch is aligned perpendicular to the workpiece surface. Re-align the torch carriage as necessary in accordance with the Assembly Manual provided. |
| Travel speed is too fast. | An increased travel speed will not allow the plasma jet to cut fully down through the workpiece while moving. This causes the plasma column to lag behind while cutting which can produce excessive edge bevel. Slow your travel speed down in increments of 10IPM until the desired cut quality is achieved. |
| Plasma torch nozzle diameter is too large. | Most plasma cutters have a range of nozzles that are rated for amperage. Typically the higher amperage nozzles will have a larger nozzle orifice diameter. This larger orifice can produce more edge angularity because the plasma jet is not as tightly focused when using a smaller nozzle size. We recommend lowering your amperage and selected a smaller fine cut nozzle if possible for your project to produce better edge angularity. |
| Incorrect cutting amperage. | Incorrect cutting amperage can product either positive or negative edge bevel. Adjust your arc amperage in 3A increments until the desired cut quality is achieved. |
| Workpiece is warped. | A warped workpiece can result in irregular cut angularity due to the fact that the torch is no longer perpendicular to the workpiece. Inspect your workpiece and clamp as necessary. If you are experiencing warpage while cutting on thinner material, we recommending cutting with a water table to eliminate this thermal distortion. |
| Improper cut height. | Cut height can have an affect on edge angularity which can produce either a positive or negative edge bevel angle. Adjust the cut height either up or down in 0.030" to reduce edge angularity. |
