The archived note for this high-speed trimming wire saw is a short, imperfect translation about the arc formed where the wire enters or leaves a cut and how the working-line length relates to the string. It should not be expanded into unsupported operating advice.
Arc at the cut boundary
The source says different degrees of arc can form during cutting and when a cut ends. The wording does not define the arc, its measurement or the exact trimming condition, so the page cannot assign a preferred geometry.
Working-line relationship
The old text connects a longer working line with a change in the string, but the translated sentence is incomplete and internally unclear. No length, weight, tension or machine setting is preserved. Rewriting that fragment as a formula would create information the source does not contain.
Purpose of the retained video
The recording can introduce the equipment and visible trimming action. A technical explanation of wire geometry should be added only after Huada supplies a verified source in clear English. Until then, the responsible version keeps the original video and flags the evidence gap instead of smoothing a damaged translation into confident but unreliable instructions.
