This industrial resistance spot welder is purpose-built for high-volume welding of shock absorber end caps and related cylindrical or sheet metal components. Featuring two automatic feeding mechanisms, the machine minimizes manual handling, shortens cycle times, and guarantees consistent weld positioning across long production runs, making it an ideal solution for automated manufacturing lines.
Rated from 100 to 250 KVA with a maximum welding thickness of 6 + 6 mm, this projection spot welding machine produces strong, forged weld nuggets on low-carbon steel, stainless steel, and coated materials. The 50% duty cycle supports continuous shift operation, while the rigid frame and CE-certified electrical system deliver long-term reliability in demanding industrial environments.
The machine integrates two independent automatic feeders that load and align shock absorber end caps and body tubes before every welding cycle. This eliminates manual clamping errors, reduces operator fatigue, and boosts output per shift. The synchronized feeding sequence also prevents missed spots and maintains consistent weld spacing throughout high-volume production.
Using resistance projection welding technology, the machine concentrates current and pressure at designed projection points, producing forged, dense weld nuggets with excellent shear and tensile strength. The 6 + 6 mm maximum welding thickness covers common shock absorber end cap combinations, while precise current control minimizes spatter and extends electrode service life.
Rated at 50% duty cycle, this spot welder is engineered for sustained operation in three-shift manufacturing environments. High-capacity transformers and efficient water-cooled electrodes keep thermal buildup under control, reducing unplanned downtime and consumable replacement costs. The result is a lower cost per weld and predictable production scheduling.
Every control panel, electrical component, and safety interlock is built and tested to CE standards. Emergency stop, overcurrent protection, and anti-touch shielding are included as standard, giving plant managers full confidence in operator safety and simplifying machine acceptance for export projects.
| Industry | Typical Workpiece | Welding Mode |
|---|---|---|
| Automotive Suspension and Shock Absorber Manufacturing | Shock absorber end caps, guide tubes, and reservoir housings | Projection welding and multi-spot resistance welding |
| Motorcycle and Two-Wheeler Parts | Fork end caps, brackets, and mounting plates | Spot welding with automatic feeding |
| Hydraulic and Pneumatic Cylinder Production | Cylinder end caps and port plates | Resistance projection welding |
| General Sheet Metal Fabrication | Brackets, supports, and formed sheet metal components | Single or twin spot welding cycles |
Resistance spot welding uses the workpiece itself as part of the electrical circuit. Two copper electrodes apply mechanical force and pass a high current through overlapping metal sheets. The contact resistance at the faying surface generates localized heat, melting a small nugget that fuses the metals together. In this machine, the twin automatic feeding mechanism positions the shock absorber end cap and tube into the welding station, after which the pneumatic cylinder closes the electrodes and the welding transformer delivers the programmed current. The entire sequence is automatically synchronized to produce consistent, high-strength joints at high speed.

The maximum welding thickness is 6 + 6 mm, meaning two sheets of 6 mm combined. This covers typical shock absorber end cap and tube wall thickness combinations. The actual weldable range depends on material grade, surface condition, and electrode configuration.
The twin feeding system automatically loads the workpiece and the end cap into the welding station, aligns them in one motion, and then triggers the welding cycle. This reduces manual handling time, prevents positioning errors, and ensures consistent weld placement, making it ideal for large batch production.
Routine maintenance includes checking electrode tips, water cooling flow, air pressure, and electrical connections. The machine is designed with easy access to all major components, and our service team provides a detailed maintenance manual as well as remote guidance whenever needed.
