Automatic Nut Transporting Resistance Spot Welding Machine with 100KVA Rated Capacity and Three-phase Power Supply

This BLM automatic nut spot welding machine is a multifunctional resistance spot welding equipment integrated with an automatic nut feeding system. It combines precision spot welding and automatic nut conveying into one machine, which greatly improves production efficiency and reduces manual operation in metal welding production lines.

Equipped with a stable pneumatic system and reliable control system, the welding machine provides stable welding current and pressure to ensure firm and beautiful welding joints. The built-in automatic nut feeder can automatically sort, convey and position nuts of different specifications, avoiding errors caused by manual placement and improving welding consistency.

It is widely applied in sheet metal fabrication, automotive parts manufacturing, hardware production, home appliance shell assembly and other industries that require high-efficiency nut spot welding. The machine supports customization of nut size, welding stroke, pressure and current to meet different production requirements.

With compact structure, simple operation, stable performance and long service life, it is an ideal equipment for automatic welding production.

• Integrated spot welder + automatic nut feeding system
• High efficiency & labor saving, no manual nut placement
• Stable welding, accurate positioning, no misalignment
• Adjustable welding pressure & current for different sheet thickness
• Widely used in automotive, hardware, home appliance welding
• Customizable for different nuts: M4 M5 M6 M8 M10 etc.

• Three-phase power supply, grid balance: Small impact on the grid with power factor as high as 0.7-0.9 (power frequency 0.4), which greatly reduces reactive power loss
• Significantly improved welding control accuracy: Inverter frequency reaches above 1000Hz, with welding current control ability and control accuracy 20 times higher than AC welding machines
• Great leap in welding quality: Current waveform is straight, nugget size is stable, spatter is less, and surface quality of solder joints is excellent
• Save basic investment and energy: Grid power demand is low, only 2/3 of AC resistance welding machines; welding time is short and electrode life is extended
• Human-computer interface: Easy to operate with multiple sets of welding specifications that can be stored and called with one key; real-time display of welding current and time; monitoring and alarm functions for welding pressure, cold water flow, and welding current
