This 200KVA copper spot welding machine is an MFDC high frequency resistance welder engineered specifically for copper wire welding applications. As a fixed spot projection welding system, it delivers high efficiency welding performance with a maximum short circuit current of up to 45KA, making it an ideal solution for manufacturers requiring reliable copper wire joining in high-volume production environments.
Designed with a hand-operated mechanism and compact structure, this resistance spot welding equipment is built for stable performance and energy-saving operation. Its thickened steel plate body ensures structural stability, while the internal water cooling system reduces welding temperature for consistent weld quality. Manufactured in our 20,000 sq.m facility with a dedicated R&D team, this copper welding machine supports diverse industrial applications including building material shops, machinery repair shops, and manufacturing plants across Philippines, Brazil, Indonesia, and Pakistan.
The medium frequency direct current power supply ensures stable welding current output with reduced spatter. This advanced MFDC design delivers superior heat control during copper wire welding, resulting in cleaner weld joints and higher weld quality consistency across production batches.
The thickened steel plate body construction provides exceptional structural rigidity even under continuous high-force welding operations. This robust frame minimizes vibration and mechanical deflection, reducing maintenance frequency and extending the machine service life in demanding production environments.
Upper and lower electrodes are manufactured from highly conductive copper alloys with auxiliary pressure support. The integrated water cooling system reduces electrode temperature during sustained operation, maintaining dimensional accuracy of weld tips, increasing electrode lifespan, and improving overall production efficiency by reducing downtime.
The spot welder stores up to 15 groups of welding modes, allowing quick switching between different workpiece specifications without time-consuming recalibration. This flexibility increases production throughput and enables fast adjustment when processing varying copper wire diameters, plates, nuts, and steel bars.
With maximum welding thickness of 5.0+5.0mm and rated power options from 40KVA to 100KVA, this fixed spot welder accommodates a wide range of low-carbon steel, coated steel plates, stainless steel, and aluminum plates. Its capability to weld copper wire and standard components makes it a versatile addition to fabrication facilities.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Electrical Component Manufacturing | Copper wire, copper plates, threaded inserts | Spot welding / Projection welding |
| Metal Fabrication | Low-carbon steel plates, coated steel sheets | Fixed-point spot welding |
| Automotive Parts Manufacturing | Stainless steel components, nuts, steel bars | Multi-mode programmable welding |
| Construction Equipment | Aluminum plates, metal wire, standard hardware | Projection welding |
The MFDC high-frequency resistance welding system converts standard three-phase AC power into a controlled direct current through its medium frequency inverter technology. During operation, the fixed workpiece is positioned between the upper and lower copper electrodes, which apply programmed mechanical force. A precisely timed high-current pulse passes through the workpiece contact points, generating resistance heat at the joint interface that melts the copper material and forms a metallurgical bond. The internal water cooling system continuously regulates electrode temperature to maintain consistent weld quality, while the microprocessor-controlled welding modes allow adjustment of current, time, and force parameters for different materials and thicknesses. This stationary machine design moves the workpiece into position, ensuring repeatable weld placement and stable output across production runs.
