RSR-2500
RSR-2500 is a capacitor discharge stud welding machine designed for very fast cycle times, low heat input, and cleaner stud attachment on finish-sensitive materials. With single-phase 220V ±10% input, 2500J energy storage capacity, and 3-6 millisecond weld time, it suits production environments that need speed, reduced distortion, and a neat visible finish.
This model represents the capacitor discharge side of the stud welding lineup, aimed at faster welding on thinner materials where appearance and controlled heat input are important.
RSR-2500 Technical Specifications
Machine classification and performance data for the RSR-2500 capacitor discharge stud welding machine.
Fast, low-heat stud welding for thin sheet and cleaner finished surfaces.
RSR-2500 is positioned for capacitor discharge stud welding applications where speed, lower thermal distortion, and surface appearance are more important than the heavier fusion profile of drawn arc welding.
Capacitor discharge welding with 3-6 millisecond weld time
Capacitor discharge stud welding is commonly selected for thin sheet and finish-sensitive work because the stored energy is released in an extremely short cycle. That helps reduce heat spread, limit backside marking, and support clean stud attachment on lighter materials.
Low heat input helps reduce distortion risk
Minimal heat-affected zone, reduced discoloration, and no reverse-side marking on thin materials make RSR-2500 a practical choice for panels, cabinets, housings, and other surface-conscious production work.
Built for very fast repetitive stud installation
Lightning-fast 3-6 millisecond weld cycles support high productivity and make capacitor discharge welding especially effective for fast-cycle manufacturing environments.
Configured for multiple common industrial metals
Suitable thickness ranges for carbon steel, stainless steel, copper, and aluminum alloy applications give RSR-2500 a wider application profile across light industrial fabrication and assembly work.
Portable size for flexible workshop placement
At 22 kg with a 490mm x 234mm x 440mm machine size, RSR-2500 stays compact enough for bench setups, production cells, and mobile shop positioning while maintaining industrial-use capability.
Where RSR-2500 fits best
- Thin sheet metal fabrication and enclosure production
- Panels, cabinets, and visible-finish assemblies
- Fast stud attachment where low distortion is important
Main values buyers compare first
Key values include single-phase 220V ±10% input, 10A input current, 180A output current, 2500J energy storage capacity, 20% rated load sustained rate, and 3-6 millisecond weld time.
Choose this process for lighter and cleaner work
RSR-2500 is the better choice when the application involves finish-sensitive work, thin material, and a cleaner visible surface. If the job requires larger studs, thicker base material, or heavier structural fastening, a drawn arc model is usually the stronger fit.
Use capacitor discharge for speed and finish quality, or move to drawn arc when stud size and base-material thickness increase.
Within the Taumaco stud welding range, RSR-2500 covers the capacitor discharge process for fast, low-heat welding on thinner material, while RSN-2500SiC addresses heavier-duty drawn arc stud welding for larger studs and thicker sections.
RSR-2500
- Capacitor discharge stud welding machine with 2500J energy storage capacity and 3-6 millisecond weld time.
- Suitable for finish-sensitive work, thinner sheet, and faster repetitive welding cycles.
- Choose this model when low distortion and clean surface appearance lead the selection criteria.
RSN-2500SiC
- Drawn arc stud welding machine for 6-22 mm studs and higher weld-energy applications.
- Better suited to thicker materials, structural fastening, and larger-diameter stud work.
- Choose this model when holding strength and heavier industrial work are more important than low heat input.
How To Choose
- Start with material thickness, stud diameter, and visible-finish requirements.
- Use capacitor discharge on thin materials and drawn arc on thicker materials or larger studs.
- Finish by confirming power supply, output demand, production speed, and accessory package.
Verify the process suitability, material thickness, package scope, and stud compatibility before order confirmation.
Published specifications, standard delivery scope, and accessory ratings are for reference only and may change without notice. Welding guns, earth cables, collets, chucks, studs, accessories, and other package components may vary by model, package, and destination market. Before ordering, confirm the required stud welding process, workpiece material and thickness, stud type and diameter, input power, production rate, surface-finish requirement, and applicable local compliance requirements for the intended application.
