Industrial Resistance Spot Welder for Copper Wire Joints

Video Demonstration

Product Overview

This industrial resistance spot welder is purpose-built for copper wire joining, delivering reliable and consistent weld quality for high-volume production lines. With a stationary frame and moving workpiece design, it simplifies operation and ensures uniform electrode pressure across every cycle. Suited for factories producing transformers, motors, cables, and copper connectors, this machine helps you reduce cycle time and maintain repeatable joint strength.

Manufactured by ChengDu Xinweihan, a leading welding equipment maker with over 20 R&D engineers and a 20,000 m² facility, this spot welder comes with robust after-sales coverage including free spare parts, field installation, commissioning, and training. Our overseas technical teams in Southeast Asia and South America provide on-site support, while video and online assistance are available worldwide.

Key Technical Advantages

Pneumatic Precision Pressure Control

The upper electrode is driven by a cylinder with fine pressure adjustment, while a dedicated air tank ensures stable standby force. This design eliminates manual guesswork and gives operators repeatable welding force for every joint.

Fast-Acting Solenoid Valve & Adjustable Stroke

A straight solenoid valve accelerates head reaction speed, boosting cycle rates and reducing airflow loss. Both working stroke and auxiliary stroke are smooth, and the lower electrode can be adjusted vertically to match different workpiece heights.

Stable High-Current Output

Water-cooled high-power SCR modules deliver strong, stable secondary current. Combined with upper-insulation secondary conductors, the machine maintains excellent electrical insulation and thermal stability even during continuous production.

Reduced Impact & Quiet Operation

Descent and return speeds of the pressure head are independently adjustable, which softens the impact on workpieces, lowers noise levels, and extends tool life. The result is a cleaner working environment and less maintenance downtime.

Durable Cooling System with Flow Monitoring

All water-circuit parts are made from copper and stainless steel, with visible flow indicators so operators can quickly confirm cooling performance. This prevents overheating and keeps weld quality consistent over long shifts.

Foot-Switch Operation for High Productivity

Simple foot-switch control frees the operator's hands for workpiece positioning, dramatically raising output per hour while reducing fatigue. Ideal for repetitive copper-wire joint tasks in assembly lines.

Frequently Asked Questions

What materials can this spot welder join?

It is specifically optimized for copper wire, but it can also weld steel, copper, and aluminum workpieces with suitable electrodes and fixtures. For non-copper materials, please consult our engineers for parameter guidance.

How do I choose the right model among DN(B)-100/160/200/250?

Select based on your maximum copper wire thickness and required electrode force. The -100 handles up to 3+3 mm, -160 up to 4+4 mm, -200 up to 5+5 mm, and -250 up to 6+6 mm. Our team can help you calculate exact needs.

Does the machine come with a test report?

Yes, every unit undergoes an outgoing inspection and ships with a Machinery Test Report. Video inspection is available upon request before delivery.

Can I get training and installation support overseas?

Absolutely. We provide free field installation, commissioning, and operator training. Additionally, we have local technical teams in several countries for on-site maintenance, and remote video support is always available.
