The Lincoln Electric SPEEDTEC 400SP is a third-generation multi-process welding power source designed for professional welders seeking high-quality, efficient welding solutions. This water-cooled package operates on 400V 3-phase power and is engineered for demanding industrial environments.

Equipped with advanced inverter technology, the SPEEDTEC 400SP delivers superior welding performance across multiple processes including Pulse MIG, MIG, Flux-cored, Stick, TIG, and TIG Pulse. Its rugged construction ensures durability under harsh conditions, while the digital communication system with Ethernet and USB connectivity enables precise traceability and monitoring of welding activities.

Key features include a pulsed MIG process that reduces spatter and heat input, enhancing weld quality especially in out-of-position applications. The machine offers premium CV MIG and Stick welding behavior, variable inductance control, synergic capability, and continuous wire feed speed and voltage control. The double-side fully potted PCB provides exceptional resistance to dust, humidity, vibration, and mechanical shocks. Additionally, the VRD (Voltage Reduction Device) functionality enhances operator safety.
