Plasma cutting kerf drag
Plasma cutting drag error is the horizontal offset of the plasma jet at the bottom of the material relative to the entry point on the surface. It is caused by travel speed and arc deflection.
Physical-Chemical Mechanism
Plasma cutting drag error is caused by the horizontal shift of the plasma jet at the bottom of the workpiece compared to the entry point at the surface. This effect is influenced by the travel speed and the dynamic arc deflection.
Metallurgical Relevance & Welding Risks
Excessive drag error can lead to uneven material removal, which in turn results in wasted material and possible quality issues in the cut. Additionally, it can cause incomplete cuts or excessive kerf width.
Workshop Practice & Instructions
To minimize drag error, set the travel speed and arc deflection precisely. You can achieve the optimal setting through trials and calibration. Recommended travel speed values are 10-20 m/min, depending on the material and the desired cut quality.
