The FRONIUS TRANSEEL 4000 PULSE POWERSOURCE is a high-performance MIG welding power source designed for professional welders requiring advanced pulse welding capabilities. It is suitable for applications involving steel, stainless steel, aluminium, and various flux-cored wires.

This powersource features a robust split system design with a separate wire feeder and an optional pulse control panel, allowing for flexible setup and extended inter-connecting hose lengths up to 8 meters. Available in 400 or 500 amp versions, it supports modular expansion with optional cooling units and water-cooled torches, enabling up to 100% duty cycle for demanding welding tasks.

The TransSteel Pulse technology incorporates Steel Transfer Technology with Pulse Controlled Spray (PCS) and a pulsed arc process that delivers up to 167 different arc characteristics. This versatility covers a wide range of materials and wire diameters from 0.8 to 1.6 mm, compatible with eight different gas mixtures. The pulse function enhances welding speed by up to 30% on thicker materials while reducing rework by 70% due to less spatter generation.

Key operational benefits include a 40% duty cycle, allowing four minutes of continuous welding at maximum output power, which improves productivity compared to typical units in this power range. The intuitive user interface enables welders to start welding quickly without prior device knowledge, requiring only the selection of gas type, wire diameter, and material thickness before operation.
