A hand stripping machine is generally designed around specific wire diameter ranges, such as small models for thin household wires and larger models for thicker industrial cables. The key point is that the machine must match both the minimum and maximum wire size. If the wire is too small, the blade may not cut properly; if too large, it may not pass through the rollers or cutting area at all.

In practical use, a hand stripping machine is often selected based on the most frequently processed wire size rather than occasional extremes. Small portable models are suitable for thin cables, while mid-range models cover mixed workshop or recycling work. Larger versions are used when thicker power cables are involved. Measuring the outer insulation diameter is important because the machine interacts with the full cable structure, not just the copper inside.

Overall, a hand stripping machine performs best when its size range is closely matched to actual working needs. Proper selection improves cutting stability, reduces material damage, and ensures smoother operation across different wire types in daily use.
