Product Details

SiC-powered stud welding for thicker material and larger fastening diameters.

RSN-2500SiC is designed for users who need a drawn arc system with a broad stud range, strong current output, and a more advanced Silicon Carbide power platform for modern industrial stud welding cycles.

SiC Advantage

Silicon Carbide technology is the core differentiator of this model

For buyers comparing machine platforms, the Silicon Carbide architecture is one of the strongest reasons to choose RSN-2500SiC. It supports high-frequency switching, reduced power loss, improved electrical efficiency, and a more compact equipment format than conventional heavy-duty power-source designs.

Process Positioning

Drawn arc welding for stronger fusion on heavier jobs

Drawn arc stud welding is widely used when higher weld energy and larger stud diameters are required. It is the better fit for thicker sections, structural fabrication, and demanding fastening work where a stronger weld deposit is needed than capacitor discharge welding usually provides.

Power Platform

Silicon Carbide technology for high-frequency, low-loss operation

Silicon Carbide semiconductor technology supports high-frequency operation, ultra-low power loss, and a more advanced power-source format than conventional IGBT-based drawn arc systems.

Dual Function

One machine for RSN stud welding and MMA manual arc welding

In addition to drawn arc stud welding, RSN-2500SiC also supports MMA mode with a 200A - 1000A current adjustment range for general maintenance, repair, and site-support tasks.

Working Range

Built for 6-22 mm stud applications

The listed stud diameter range makes RSN-2500SiC suitable for a broad span of industrial fastening tasks, from medium studs through larger drawn arc applications used in steelwork, equipment frames, and structural assemblies.

Industrial Use

Compact form for its class with full industrial positioning

With a 47.5 kg machine weight and compact 650mm x 305mm x 585mm dimensions, the equipment is easier to position and handle than larger traditional systems while still targeting demanding industrial stud welding work.

Typical Applications

Where RSN-2500SiC fits best

  • Structural steel fabrication and stud fastening
  • Industrial sheet, plate, and frame assembly
  • Production work needing larger stud diameters and deeper fusion
Technology Focus

Why buyers look for SiC-powered models

Silicon Carbide technology is associated with faster switching response, lower heat loss, and improved power density. In practical buying terms, that helps position RSN-2500SiC as a more advanced and more premium machine within the stud welding range.

Key Operating Data

Main values buyers compare first

Key values include AC 380V three-phase input, 90 KVA rated input capacity, 200A - 2500A RSN current range, 200A - 1000A MMA current range, 6mm - 22mm stud diameter range, and 0 - 3 seconds weld time adjustment.

Materials

Compatible material direction

RSN-2500SiC is engineered for welding carbon steel and cast iron materials, which aligns with its heavier-duty positioning in drawn arc stud welding work.

Stud Welding Machine Series

Match the welding process to the job: drawn arc for heavier structural fastening, capacitor discharge for fast welding on thinner material.

Taumaco's stud welding range can be separated into two practical working directions. RSN-2500SiC covers higher-energy drawn arc stud welding for larger diameters and thicker sections, with Silicon Carbide technology giving it a stronger advanced-technology position in the lineup, while RSR-2500 focuses on capacitor discharge welding for speed, lower heat input, and cleaner results on thinner material.

RSN-2500SiC

  • Drawn arc stud welding machine with 6mm - 22mm stud diameter range, RSN + MMA dual-function capability, and Silicon Carbide power technology.
  • Better suited to thicker workpieces, larger studs, structural fabrication demand, and buyers looking for more advanced power-source technology.
  • Choose this model when stronger fusion and heavier-duty fastening are the main priority.

RSR-2500

  • Capacitor discharge stud welding machine for high-speed stud attachment with low heat input.
  • Well matched to thinner sheet, decorative panels, cabinets, and applications where backside marking should be minimized.
  • Choose this model when fast cycle time and surface-sensitive work matter most.

How To Choose

  • Start with base-material thickness and stud diameter, then confirm process type.
  • Use drawn arc for heavier sections and capacitor discharge for thinner material and lower distortion risk.
  • Finish by checking available power, production volume, and accessory requirements.
