Böhler Welding’s patented MultiLine Three Level® inverter technology is at the heart of the TERRA NX 400 PMC. It provides exceptionally high energy efficiency (PF close to 1), which directly translates into lower electricity bills and a lower environmental impact.

A key advantage is also the reliability and stability of the welding arc, even when the supply voltage fluctuates. High-speed digital arc control guarantees excellent dynamics and precision, which is essential for advanced pulsed processes. In addition, this technology allows for a significant reduction in size and weight compared to traditional transformers, increasing its mobility and facilitating field work.

ArcDrive® is an enhanced, digitally controlled MIG/MAG welding process from Böhler Welding, designed for maximum arc stability and reactivity. This makes welding easier, especially in forced positions and when welding hard-to-weld materials.

The main benefit of ArcDrive® is a significant reduction in weld spatter, which minimizes the need for time-consuming post-processing and reduces the cost of cleaning materials. The process provides excellent weld quality and is ideal for welding carbon steels, stainless steels, aluminum and core wires, guaranteeing a smoother weld face and better fusion.

PulsDrive® is a digital MIG/MAG pulse welding process that implements the “one pulse – one drop” principle. This provides unparalleled control over the transfer of metal into the weld pool, which is crucial when welding thin sheet metal, aluminum and stainless steels.

With PulsDrive®, the welder achieves excellent arc control, minimal heat introduction (reducing distortion by up to X%) and an exceptionally aesthetic and smooth weld face, often eliminating the need for additional finishing. The process is particularly valued for reducing the risk of burn-through and porosity, guaranteeing welds of superior metallurgical quality and strength.

The Böhler Arc system is an advanced library of synergistic welding programs optimized for a wide range of materials, wire diameters and shielding gases. Access to hundreds of predefined settings (depending on software configuration) significantly speeds up job preparation and guarantees repeatable results.

The professional only selects the type of material, wire diameter and gas, and the TERRA NX 400 PMC automatically selects the optimal welding parameters. This not only saves time, but also ensures the achievement of excellent weld quality every time, even with a less experienced operator. Böhler Arc allows you to take full advantage of the machine’s potential and its advanced processes.

The integrated DualFeeder system of the TERRA NX 400 PMC DUALFEEDER is a revolutionary solution for increased productivity and operational flexibility. Two independent 4-roll feeding mechanisms allow the machine to be permanently armed with two different types of welding wires (e.g. steel and aluminum) or two different diameters of the same wire.

This allows the welder to switch instantly between tasks requiring different consumables without the need for time-consuming rearming of the MIG/MAG fixture. This directly translates into reduced production downtime, optimized workflows and increased profitability of ongoing projects. Ideal for workshops with diverse production profiles.
