Pneumatic Clamps

Insulation Platform

Mobile Positioning Block

Six Gun Head Mechanisms

  • Adopts integrated welded frame structure, with good rigidity, stability and durability. 

  • The walking mechanism is all driven by high-precision servo clicks to achieve precise positioning.

  • The welding platform is a floating ball insulation platform, which can avoid surface scratches caused by the friction of the workpiece on the insulation platform.

  • Double stations can be set according to customer product requirements, and alternating use of double stations can greatly improve production efficiency.

  • The welding gun mechanism adopts servo drive + slide cylinder, the welding speed and pressure are stable and adjustable, and can adapt to the deformation of the plate surface.

See for yourself: the Video of the ERSM® RS SERIES!

The RS series CNC stud welding automatically feeds nails, automatically welds, and can weld screws of various specifications at the same time, with accurate positioning and firm welding.

CNC stud welding components

Energy storage welding machine

Energy storage welding machine

Double-capacitor automatic welding machine with communication, two sets of capacitors inside, one set for working, the other set for energy storage standby or connecting to manual stud welding machine, twice as efficient, twice as long life, charging time can be almost ignored.

Automatic nail feeding device

Automatic nail feeding device

The automatic nail feeding device includes a nail selector, pneumatic nail feeder, automatic welding gun, and nail feeding tube. It enables efficient nail feeding and welding with high reliability, automatic nail detection, and improved system efficiency. The structure is simple, stable, and durable. The dedicated mechanism supports large loads, operates quietly, and reduces energy consumption. Nail specifications range from M3-M8, with custom options available.

CNC system for stud welding

CNC operation interface

The system supports parameter saving to record point size and gun head data for quick welding of similar products. It features a touch CNC system with an imported multi-axis controller, ensuring stability and reliability. A full-color handheld box simplifies adjustments. The compact servo controller integrates three axes for easy installation. Three programming methods—teaching (infrared indicators for fast handwheel input), CAD (drawing imports), and coordinates (table-based input)—ensure flexibility. Additional features include patching, dry running, and QR code program calls.

Slant feed gun

Slant feed gun

The oblique-feed nail welding gun has a simpler and more reasonable structure, longer service life, better welding effect, comprehensive and stable functions, and a durable gun head.

Direct delivery gun

Direct delivery gun

The gun head is small, the structure is simple, and the nailing speed is fast. It is suitable for welding stainless steel and cold-rolled steel plate materials, but not suitable for long-term welding of galvanized materials.

More optional accessories

储能 拉弧通用焊枪

Drawn arc welding gun

  1. The welding mode can be divided into two types (front discharge and rear discharge);
  2. Energy storage arc, general welding gun;
  3. There is a pressure spring inside the welding gun;
  4. Fully automatic energy storage, arc welding general welding gun, can weld the same specifications and different lengths of welding nails at the same time (energy storage and arc welding nails are both available)

Electric milling cutter

Chip removal technology:Solve the problems of chip jamming and chip collapse caused by surface differences during milling, improve processing quality, and reduce the workload and cost of subsequent processing.

Protective function:Prevent metal fragments from splashing during riveting, protect the safety of operators, reduce adhesion, and improve processing stability.

Air blowing chip removal:The built-in air blowing device automatically removes iron chips without manual processing, ensuring efficient and accurate processing.

Semi-automatic nailing device

The screws are manually placed in the corresponding workstations, and then the nailing mechanism inside the manual nail feeding device pushes the screws into the welding chuck, driving the welding gun unit to move the welding position to weld the nails. It can feed special big head screws, headless screws, screws with shorter lengths, etc.

Frequently Asked Questions

When processing galvanized sheet, if the surface is not treated, the processing quality cannot be guaranteed and the post-processing workload is also large. The milling cutter can adjust the depth of the delamination, making the welding of nails more firm and making the processing area more beautiful. The milling cutter has the best welding effect on the sheet between 1mm and 3mm.

After automatic welding, nails with curved surfaces will be produced, making the welding more solid when melting, while after manual welding, nails have no slope and are prone to loose welding. After automatic welding, there is no mark and no need for grinding, which is suitable for appearance parts.

  • The straight feed gun has a small gun head and a fast nailing speed, which is suitable for welding small nails and long nails. The disadvantage is that it is very easy to have a loose welding phenomenon.
  • The oblique feed gun is more stable than the straight feed gun, so it has a longer life, better welding effect, and comprehensive functions. The welding gun is equipped with an automatic ejector inside, which is suitable for various materials.
