Manual Feeding vs Automatic Coil Feeding: Which Is Better for 4–9mm Mesh Welding?

When producing welded mesh with wire diameters between 4 mm and 9 mm, the wire feeding method has a direct impact on labor cost, production stability, and overall efficiency.
Two feeding methods are commonly used in the market: manual wire feeding and automatic coil feeding. Understanding the differences between them is critical when selecting the right mesh welding machine.

1. Manual Feeding: Traditional but Labor-Intensive

Manual feeding is the conventional method used on many older or semi-automatic mesh welding machines. Operators manually place each longitudinal wire into the welding area before each welding cycle.

Main Characteristics:

Each wire is inserted by hand

Frequent machine stops for wire loading

Strong dependence on operator skill and experience

Limitations for 4–9mm Wire:

High labor demand, especially for thick wires

Low feeding efficiency, limiting overall output

Inconsistent wire alignment, affecting mesh flatness

Increased downtime between welding cycles

For small-scale production, manual feeding may still be acceptable. However, as wire diameter increases and output requirements grow, its disadvantages become more obvious.

2. Automatic Coil Feeding: Designed for Modern Mesh Production

Automatic coil feeding replaces manual insertion by feeding longitudinal wires directly from wire coils. This method is especially effective for medium and large wire diameters, including 4–9mm.

Key Advantages:

Continuous feeding from wire coils

Supports up to 9mm coil wire

No need to stop the machine for wire loading

Significantly reduces manual labor

With this system, operators only need to load the coils once, and the machine handles feeding automatically throughout production.

3. Efficiency Comparison: Labor and Output

For factories targeting stable, high-volume production, automatic coil feeding clearly provides a stronger advantage.

4. Welding Quality and Mesh Flatness

Automatic coil feeding works together with:

Multi-stage straightening rollers

Precise wire positioning systems

Stable tension control

This combination ensures that longitudinal wires stay aligned during welding, resulting in:

Better mesh flatness

Uniform mesh openings

Stronger and more consistent welding joints

Manual feeding, by contrast, often leads to slight misalignment that affects final product quality, especially with thicker wires.

5. Cost Consideration: Short-Term vs Long-Term

Manual feeding may appear cheaper at the initial investment stage. However, in real production:

Labor costs increase over time

Production efficiency is limited

Output per shift remains lower

Automatic coil feeding reduces manpower needs, increases daily output, and stabilizes quality. Over time, this results in a lower cost per mesh panel and a faster return on investment.

6. Which Feeding Method Is Better for 4–9mm Mesh Welding?

For 4–9mm welded mesh production, automatic coil feeding is clearly the better choice when:

Labor costs are rising

Production runs are long

Consistent quality is required

Thick wire needs stable feeding

This is why DAPU’s 4–9mm Automatic Welded Mesh Welding Machine adopts an advanced coil feeding system designed specifically for heavy-duty mesh production.

Conclusion

Choosing the right wire feeding method is not just a technical decision—it directly affects productivity, operating cost, and product quality.
For manufacturers looking to produce high-strength welded mesh efficiently and reliably, automatic coil feeding offers a clear and proven advantage over manual feeding.
