Böhler Welding’s patented MultiLine Three Level® inverter technology is at the core of the TERRA NX PME series. It provides exceptional energy efficiency, minimizing losses and lowering operating costs. Crucially for the welder, this technology enables extremely fast and precise control of the welding arc.

With MultiLine Three Level®, the arc is more stable, and the dynamics of its control allows it to perfectly handle changes in arc length or welding conditions. This translates into higher weld quality, fewer spatters, and increased reliability of the device, even when working intensively in harsh industrial environments. In addition, this technology contributes to a reduction in the size and weight of the power source compared to traditional solutions.

ArcDrive is a fundamental enhanced MIG/MAG process developed by Böhler Welding and available on the TERRA NX 400 PME. It features an exceptionally stable and dynamically responsive welding arc, which greatly facilitates welding, especially in forced positions and when welding hard-to-weld materials.

The main benefit for the professional is a significant reduction in weld spatter, which minimizes the need for time-consuming post-processing and reduces material costs. ArcDrive provides excellent control over the weld pool, resulting in high quality welds and deeper fusion. The process is ideal for welding carbon steels, stainless steels, aluminum and cored wires, providing repeatable and reliable results.

PulsDrive is a digitally controlled MIG/MAG pulse welding process that takes quality and precision to a new level. A key feature of PulsDrive is the “one pulse – one drop” principle, which means perfect control of material transfer into the welding pool.

With this precision, the welder achieves excellent arc control, minimal spatter and an exceptionally smooth weld face, which is especially important when welding thin sheet metal and materials such as aluminum and stainless steels. PulsDrive reduces heat introduction (HI), which minimizes material distortion and preserves the mechanical properties of the material. The result is not only aesthetics, but also increased strength of welded joints.

The Böhler Arc system on the TERRA NX 400 PME is a collection of advanced synergy programs that dramatically simplify and speed up the setting of optimal welding parameters. The user only selects the type of material, wire diameter and shielding gas type, and the device automatically selects the remaining parameters, guaranteeing ideal arc characteristics.

The benefit for the professional is significant time savings and elimination of setup errors. Böhler Arc ensures reproducible welding results independent of the operator, which is crucial in mass production. The programs are the result of Böhler Welding’s years of research and experience, covering a wide range of materials and applications, including the welding of carbon steels, stainless steels, aluminum and cored wires.
