Sigma² 500 Pulse is much more than a simple semi-automatic! It offers a full spectrum of advanced MIG/MAG features. Pulse Welding provides superior heat control, minimizes spatter and produces high quality welds on stainless steel, aluminum and thin sheet metal. The unique DUO Plus™ technology is a type of “slow pulse” that improves the appearance of the weld face, giving it a TIG-like aesthetic – ideal for welding boundary layers. PowerArc™, on the other hand, guarantees deep and secure fusion, essential for welding thick materials and responsible structures. These features, available through the advanced Pulse panel, put this machine in the league of professional tools for the most demanding tasks.

Need the power to weld thick parts without compromise? The Sigma² 500 Pulse delivers as much as 500 Amps of maximum current and features an impressive duty cycle – 420 Amps at 100% load at 40°C! This means you can run long, uninterrupted welds at very high performance, which is crucial in heavy fabrication, mass production and robotic applications. The robust inverter design ensures a stable arc and repeatable parameters. It’s a machine built for heavy-duty work in demanding industrial environments where performance and reliability count.

The Sigma² 500 Pulse is a truly versatile tool for the modern workshop. In addition to advanced MIG/MAG functions, it also offers MMA (shielded electrode) welding, which is useful for assembly, repair work or welding in hard-to-reach areas. What’s more, thanks to its high power, the device is also capable of electro gouging – a process essential for removing defective welds, preparing edges or removing excess material. This multi-functionality means that the Sigma² 500 Pulse can replace several machines in the workshop, increasing flexibility and efficiency.

Despite its advanced capabilities, the Sigma² 500 Pulse was designed with user convenience in mind. It is controlled via a digital panel (Pulse panel required for full functionality), which offers access to synergy programs for easy parameter selection. It is possible to save your own settings in the device’s memory. Revolutionary Intelligent Gas Control (IGC®) technology was available as an option, which can reduce gas consumption by up to 50% (check if the unit offered has this option). The unit also had the ability to update its software via SD card, a testament to its modern architecture (although the availability of new updates for the Obsolete model is limited). The device is also robot-ready (requires an RCI interface).

Migatronic’s Sigma² series is renowned for its robustness and reliability in industrial environments (IP23 protection class). Although this model is officially discontinued by the manufacturer, its proven design and build quality guarantee a potentially long service life. Crucially, when you buy this used unit from us, you are purchasing it from Migatronic’s official distributor and service in Poland. This means access to our expert advice, technical support, and potentially better service options and access to parts (as they become available for discontinued models) than if you purchased from an unauthorized source. We give you the confidence and security to purchase proven premium equipment.

This is a rare opportunity to come into possession of a high-tech Migatronic Sigma² 500 Pulse welder in virtually perfect condition – “like new”! This used unit has been thoroughly inspected by us and is fully operational. It offers features (such as Pulse, DUO Plus™, PowerArc™, IGC®*, robotization readiness) that still put it at the forefront of industrial equipment. When you take advantage of this offer, you gain access to premium equipment with a proven reputation, at a price not available for new machines with similar capabilities. It’s a smart investment for businesses and professionals looking for superior performance and versatility without having to spend a fortune on the latest model. **Take advantage while it’s available!
