Slow travel speed. |
Backside dross can occur when cutting if the travel speed used is too slow. Try increasing your travel speed by 5 IPM increments until the amount of dross is reduced. |
Cut height is too low. |
If the cut height is too low, this can cause more backside dross to form. Try increasing the cut height in 0.030” increments until the back side dross is reduced. |
Cutting amperage is too high. |
If the cutting amperage is too high, this can cause an increase in the amount of backside dross. Try reducing the cutting amps in increments of 3A until the amount of dross is reduced. |
Large nozzle orifice diameter. |
A larger nozzle orifice can result in an increased presence of backside dross. Consult your plasma cutter manufacturer for the availability of smaller nozzle sizes that are compatible with your cutting torch. |
