Original product description
The ALPHA RSN-2500 is a three-phase 380 V industrial stud welding machine offered in Compact and Large configurations. Both versions use IGBT inverter technology, operate at 50/60 Hz, and provide a no-load voltage of 100 V.
A digital display shows welding current and welding time, while the control panel is described as suitable for straightforward adjustment. The RSN-2500 Compact has a stated current range of 200–2500 A, rated input capacity of 99 kVA, rated input of 150 A, and a maximum specified weldable stud diameter of 22 mm.
Its listed dimensions are 66 × 39 × 76 cm and its weight is 75 kg. The RSN-2500 Large has a stated current range of 300–2500 A, rated input capacity of 116 kVA, rated input of 185 A, and a maximum specified weldable stud diameter of 25 mm. Its listed dimensions are 68 × 36 × 96 cm and its weight is 105 kg.
Both configurations list a maximum weldable stud length of 400 mm, efficiency of 85%, power factor of 0.9, and Class F insulation. The equipment is air-cooled and uses a vertical, one-body construction. Automatic voltage compensation is specified for managing power-grid voltage fluctuations.
Key components are described as having protection against dust, moisture, and water;buyers should request the exact enclosure or ingress-protection rating if required by their operating environment. Stated application examples include steel structures, building floor slabs, and bridges.
These examples do not establish suitability for every stud, base metal, joint design, or structural procedure.
Before ordering, confirm the required configuration, stud diameter and length, stud and workpiece materials, welding procedure, duty cycle, available three-phase electrical service, required accessories, and applicable project codes.
Buyers should also verify which certification documents apply to the exact machine and destination market, as well as the included cables, gun, consumables, packaging, commissioning support, and warranty terms.
