The PME configuration means that the URANOS NX 4000 PME is a powerful, separate welding power source that works with external wire feeders (such as the Böhler Welding WF NX). This design provides maximum flexibility in the organization of the workstation, allowing the source to be placed in an optimal location and the feeder to be placed directly at the welding site.

The benefit for the professional is increased working range, the ability to work in hard-to-reach areas and easier integration with automated systems. PME models are designed for the toughest industrial applications, offering the robustness and reliability needed when welding large structures.

The patented greenWave® inverter technology from Böhler Welding is a guarantee of exceptional energy efficiency. With a power factor (PF) close to unity (≈ 0.94-0.99), the unit draws virtually only active power from the grid, significantly reducing energy losses and lowering electricity bills by up to 30% compared to conventional sources.

The technology also provides excellent protection against unstable supply voltages and minimizes interference introduced into the electrical grid. For the professional, this means stable and reliable operation of the device even under difficult power supply conditions, as well as lower operating costs and a lower environmental impact.

The URANOS NX 4000 PME uses advanced, patented MultiLine Three Level® inverter technology. This multi-level power conversion system provides exceptional performance, reliability and extremely fast response of the welding arc control system.

Thanks to this technology, the device features reduced dimensions and weight relative to the power offered, making it easier to transport and install. The key benefit for the welder is the precise and dynamic control of welding parameters, which translates into higher weld quality, less spatter and increased process stability, even in the most demanding applications.

ArcDrive is Böhler Welding’s fundamental improved MIG/MAG process, featuring an exceptionally stable and dynamically responsive welding arc. It facilitates welding in all positions, minimizing the risk of errors and increasing comfort.

A key benefit is a significant reduction in weld spatter, which translates into time and cost savings in weld post-processing. The ArcDrive is ideal for welding a wide range of materials, including carbon steels, stainless steels, aluminum and cored wires, ensuring high quality and repeatable joints.

PulsDrive is an advanced digital MIG/MAG pulse process based on the “one pulse – one drop” principle. It provides excellent control over the transfer of metal into the weld pool, which is crucial when welding thin materials, aluminum, stainless steels and in forced positions.

By precisely controlling the pulse energy, PulsDrive minimizes heat introduction, reducing material distortion and improving the mechanical properties of the joint. Professionals will appreciate the excellent arc control, the ability to achieve smooth and aesthetically pleasing welds without spatters, and the option to weld with Double Pulse for TIG arc-looking welds.

QuickPulse is an innovative combination of the advantages of RapiDeep and PulsDrive processes. It provides significantly higher welding speed (up to 50% faster than standard pulse) while maintaining deep penetration and low linear heat input (Heat Input).

This process is particularly effective for welding stainless steels and aluminum, where both high productivity and excellent weld quality are required. QuickPulse allows you to increase productivity without compromising quality by reducing distortion and improving the appearance of the weld face. The availability of this feature may depend on software configuration.

CladPulse is a specialized pulsed MIG/MAG process optimized for surfacing (cladding). It is characterized by very low dilution (mixing of the parent material with the cladding), which is crucial for maintaining the required properties of the clad layer, often already in the first layer.

The process uses a soft, stable arc, providing high surfacing efficiency and excellent surface quality. CladPulse is ideal for applications requiring protection against corrosion, abrasive wear or erosion, allowing efficient deposition of protective layers and reconditioning of machine parts. The availability of this feature may depend on software configuration.

RapiDeep is an innovative MIG/MAG process from Böhler Welding that generates a highly concentrated welding arc. The result is much deeper material penetration with less heat input compared to standard short-circuit welding.

The main benefit is the ability to increase welding speeds by up to 50%, which directly translates into higher productivity and lower unit costs. RapiDeep is particularly recommended for welding carbon and stainless steels, where it allows for excellent fusion while minimizing distortion. The availability of this feature may depend on the software configuration (e.g., SteelDrive package).

The Böhler Arc system is a library of advanced synergy programs precisely tailored to different materials, wire diameters and shielding gases. The URANOS NX 4000 PME can offer up to 600 such programs, covering MIG/MAG, MMA and TIG DC welding.

After selecting the material, wire and gas, the device automatically selects the optimal welding parameters, which greatly simplifies and speeds up the setup. For the professional, this means time savings, guaranteed repeatability of results, and ease of achieving high-quality welds even when welding unusual materials or in complex applications. The Böhler Arc system is constantly evolving, offering newer and newer synergy curves.

The myNX function is a unique ability to fully personalize the configuration of the URANOS NX 4000 PME. The user can customize the interface, available functions, and even software packages and synergy programs to suit their specific needs and preferences.

With myNX, the welder becomes a tool that is perfectly tailored to specific tasks and operator skills. The ability to create your own settings, lock unused functions or upload dedicated process packages (e.g. for specific alloys) increases work efficiency, minimizes the risk of errors and allows you to use the full potential of the machine.
