**Product Description** Arc Inverter IGBT Stud Welding Machine RSN7-2500 The China IKING IGBT inverter type drawn arc stud welder is primarily used for the installation of stud fusion welding in steel structure construction, bridges, railways, and other similar projects. It features functions such as preset weld time, preset weld parameters, and digital display. The precise preset time can reach up to 0.01 seconds, and the preset current can be as accurate as 1 ampere, significantly improving welding reliability and stability while ensuring ease of operation. The main power unit of the welding machine is compact and lightweight, allowing it to operate continuously for 24 hours. It includes an anti-misoperation design that prevents repeated welding on the same point. Additionally, it has short-circuit protection and circuit-breaker protection, which safeguard the control board and allow smooth restart after troubleshooting. These protective measures ensure a low failure rate and extend the lifespan of the welding machine. **Features:** - Lightweight and easy to maintain - Stable and reliable welding quality - Energy-efficient and environmentally friendly - Widely used in industries such as steel structures, shipbuilding, chemical, construction, metallurgy, automotive, bridge building, boiler manufacturing, and chassis production. **Technical Data:**
