Böhler Welding’s patented MultiLine Three Level® inverter technology is at the heart of the TERRA NX series sources. It provides exceptional energy efficiency, which translates into lower electricity bills and a lower environmental impact. A key advantage is the instant and precise control of the welding arc, which enables the highest quality welds even in difficult conditions.

The technology also allows for a significant reduction in size and weight compared to traditional transformers, while maintaining, and even increasing, reliability and power. For the professional, this means easier transportation, greater mobility on the jobsite, and reliability of operation even when the mains power supply is unstable, which is crucial in industrial and field applications.

ArcDrive is a fundamental improved MIG/MAG process developed by Böhler Welding, designed to provide an exceptionally stable and highly reactive welding arc. This characteristic significantly facilitates welding, especially in forced positions and when welding hard-to-weld materials.

A key benefit for the welder is a significant reduction in weld spatter. This means less time-consuming post-processing, cleaner welds and savings in consumables. The ArcDrive process is ideally suited for welding carbon steels, stainless steels, aluminum and cored wires, providing excellent joint quality and increased productivity.

RapiDeep™ is a revolutionary MIG/MAG welding process available on Böhler Welding equipment with the SteelDrive software package. Its main goal is to deliver much deeper weld penetration while reducing the amount of heat input (HI) into the weld material. This results in less distortion and better mechanical properties of the joint.

The most important benefit for the user is the ability to increase welding speeds by up to 50% compared to standard MIG/MAG methods. This directly translates into higher productivity, shorter production cycles and reduced costs. RapiDeep™ is particularly effective when welding steel, providing excellent fusion and high weld quality, even with thicker materials.

Böhler Arc is an advanced synergy program system integrated into Böhler Welding equipment, and in the SteelDrive version its capabilities are significantly expanded, offering up to 600 predefined welding curves. This system automatically selects the optimal welding parameters (arc voltage, wire feed speed) based on the selected material, wire diameter and shielding gas type.

For the professional, this means a huge simplification and acceleration of the machine setup, minimization of the risk of errors, and a guarantee of reproducible, high-quality welds. Even for complex welding tasks, the SteelDrive version of Böhler Arc provides precise control of the process, allowing the welder to focus on the arc guidance technique. This intelligent support translates into higher productivity and excellent steel welding results.

The SteelDrive software package is a key differentiator for advanced models of Böhler Welding equipment such as the TERRA NX 500 MSE. It is not a single process, but a comprehensive software solution that unlocks the full potential of the welder, especially in steel welding. SteelDrive integrates and manages advanced functions and welding processes.

With SteelDrive, users gain access to innovative processes such as RapiDeep™ for increased penetration and speed, and an expanded library of Böhler Arc synergy programs (up to 600 curves) specifically optimized for different steels. This package often also includes an advanced color LCD display for easy navigation and precise parameter setting. SteelDrive is your guarantee of maximum productivity, precision and repeatability in professional steel welding.
