The i-Series Inverter Stud Welding Machine is primarily designed for shielded stud welding with ceramic ferrules. Featuring a compact and lightweight design, powerful performance, and excellent portability, the 2500i model excels in welding studs ranging from φ10 to φ25 mm, delivering outstanding welding quality. As one of the best-selling stud welding machines on the market, it has been widely used in major projects such as the Shanghai-Suzhou-Nantong Yangtze River Bridge. Additionally, it is suitable for welding M8 to M24 studs.
| Technical Advantages of I-Series Inverter Arc Stud Welding Machine |
|---|
| 1. IGBT Inverter Technology |
| (1) Significantly reduces weight and volume-only 1/4 the weight of traditional welding machines. Easy to transport. |
| (2) Greatly reduces copper and iron losses, improving efficiency and energy savings. |
| (3) High switching frequency (20 kHz), greatly enhancing dynamic output characteristics. |
| 2. Advanced Microprocessor Control Technology |
| (1) Easy arc ignition, minimal spatter, stable current, and aesthetically pleasing welds. |
| (2) Enhanced performance to meet various stud welding process requirements. |
| (3) Wide current adjustment range (e.g., 2500i: 100A-2500A) and broad welding time range (10ms-3000ms), enabling full-cycle stud welding. |
| (4) Pre-set gas pre-flow and post-flow timing for energy-efficient shielding gas protection. |
| (5) Over-temperature, over-current, over-voltage, and under-voltage protection functions. |
| (6) Anti-repeat welding function: If the stud fails to ignite, the gun switch must be released and re-pressed after proper contact to prevent overheating or burn-through. |
| 3. Comprehensive Functional Design |
| (1) Dual-fan, dual-channel cooling system protects power electronics from overheating damage. |
| (2) Optimized reactor and electronic arc ignition circuit improve arc stability and performance for high-quality welds. |
| (3) Electronic thrust circuit enhances long-cable welding performance for extended-distance applications. |
| (4) Anti-short circuit protection: If the gun control cable shorts, the internal DC circuit breaker trips to prevent component damage. |
| (5) Strong adaptability to unstable grid voltage (320V-440V), ensuring stable operation. |
