What would excessive drag lines indicate when oxy-fuel cutting?

Excessive drag lines during oxy-fuel cutting indicate that the cutting torch is being moved too slowly or at an incorrect angle, resulting in molten metal being dragged along the cut. This often leads to a rougher cut surface and increased heat input, which can cause warping or distortion of the material. Additionally, it may signal that the cutting flame is not properly adjusted, potentially leading to inefficient cutting and poor-quality results. Adjusting the speed and angle of the torch, as well as ensuring optimal flame settings, can help minimize drag lines.
