Car Spot Welding Machine

Car spot welding machines are essential equipment in automotive manufacturing and body repair. Based on the principle of resistance heating, they fuse multiple layers of metal sheets under electrode pressure to create strong and aesthetically pleasing welds. This series covers medium-frequency inverter DC, AC, and other technologies, offering efficient, stable, and energy-saving solutions for production lines, mobile repairs, and more. Widely used in body-in-white welding, parts manufacturing, and aftermarket sheet metal repair.

Stable Output, Consistent Welds
High-performance welding transformer and precision controller ensure stable current for consistent weld quality. MFDC technology provides 1000Hz DC output with 1ms control precision, significantly reducing welding spatter.

Adaptable to Multiple Materials
Capable of welding cold-rolled steel, galvanized steel, hot-formed steel, high-strength steel, aluminum alloys, and more. Select models achieve up to 6.0+6.0mm carbon steel capacity.

Energy-Efficient, Lower Operating Costs
MFDC technology offers higher thermal efficiency and lower energy consumption compared to traditional AC welders. Duty cycle up to 20% supports continuous high-intensity operations.

Intelligent Control, Easy Operation
Microcomputer controller stores multiple welding schedules, supporting constant voltage, constant current, and multi-pulse discharge modes. Touchscreen HMI for intuitive parameter setup.

Water Cooling System, Sustained Performance
Transformer and electrodes are equipped with circulating water cooling, effectively managing temperature rise for reliable long-duration operation.

Flexible Configuration, Production-Ready
Compatible with robotic workstations and automated welding fixtures, or used as standalone units. Non-standard customization available for specific workpiece requirements.
