Coil Nail Point Welding Machine

Professional for repairing welding defects coil nails

During coil nail production, unstable welding points, transportation impact, or long-term storage May occasionally cause loose connections between nails and wire. The coil nail point welding machine is specially designed to repair defective welding areas and restore the strength of wire-collated coil nails without replacing the complete coil.This compact welding solution is widely used by coil nail manufacturers, distributors, and fastener processing companies that require an efficient method for quality improvement and product recovery. Instead of scrapping coils with minor welding problems, operators can quickly repair damaged sections and reduce material waste.

Unlike large automatic coil nail production lines, this coil nail spot welding machine focuses on flexible repair operations. It provides accurate resistance welding at specific points, allowing operators to reinforce weak connections between nail shanks and steel wires.

The machine is suitable for repairing: Wire collated coil nails, Pneumatic nail coils, Export coil nail products requiring strict quality standards, By improving welding reliability, manufacturers can increase finished product acceptance rates and reduce unnecessary production losses.

The DN1-16 model adopts a resistance spot welding structure with a rated capacity of 16 kva. The welding current and welding time can be adjusted according to different nail specifications and wire conditions.

The welding parameters include:

• Welding time adjustment: 0–9.99 seconds
• Adjustment stages: 7 levels
• Extended electrode arm length: 250 mm

The adjustable settings allow users to achieve stable welding results for different coil nail materials and sizes.

The equipment features a compact structure with a packing dimension of only 650*420*550 mm and a gross weight of approximately 150 kg, making it easy to install in existing production workshops or quality inspection areas.The welding transformer adopts air cooling, while the electrode system uses water cooling to maintain stable performance during repeated operation.With a single-phase 220v / 50hz power supply, the machine can be conveniently used in different industrial environments without requiring complex electrical installation.

For coil nail manufacturers, defective welding does not always mean the entire product batch must be discarded. The coil nail point welding machine provides a practical solution for repairing small welding defects, improving finished product quality, and maximizing raw material utilization.

It is especially valuable for factories producing export-standard coil nails where appearance, welding strength, and packaging integrity are strictly controlled.

The coil nail point welding machine provides manufacturers with an economical and efficient way to solve welding defects, reduce product waste, and improve customer satisfaction. It is an essential auxiliary machine for professional coil nail production facilities focusing on stable quality and reliable performance.
