ArcDrive is Böhler Welding’s fundamental enhanced MIG/MAG process, featuring an exceptionally stable and dynamically responsive welding arc. This feature significantly facilitates welding, especially in forced positions and when welding thin materials. A key benefit is the significant reduction in spatter, which minimizes the need for time-consuming post-processing and reduces the cost of cleaning materials.

The ArcDrive process is optimized for a wide range of materials, including carbon steels, stainless steels, aluminum and cored wires. It provides excellent control over the weld pool, resulting in higher weld quality, better fusion and an aesthetically pleasing face. The reliability and repeatability of the ArcDrive process make it an invaluable tool for professionals striving for perfection.

RapiDeep® is a revolutionary MIG/MAG welding process, available on Böhler Welding equipment with the SteelDrive package, that radically changes the approach to productivity and quality. Its key feature is the generation of a concentrated arc that provides much deeper material penetration while reducing heat input (Heat Input). This translates directly into an increase in welding speed of up to 50% compared to standard MIG/MAG methods.

Less heat input minimizes the risk of material distortion and changes in structure, which is particularly important when welding high-strength steels and thin sheets. RapiDeep® produces excellent quality fillet and butt welds with fewer stitches, reducing the use of consumables and labor time. It’s the ideal solution for mass production and applications where speed and superior quality count.

The MultiLine Three Level® inverter is a patented technology developed by Böhler Welding (Selco) that is at the heart of the TERRA NX series. It provides exceptional energy efficiency and operational reliability, resulting in lower operating costs and longer device life. Thanks to its advanced three-level architecture, this inverter enables extremely fast and precise control of the welding arc, which is crucial for process stability and the quality of the welds obtained.

Another major benefit of this technology is the significant reduction in size and weight of the power source compared to traditional transformer solutions, which increases the mobility of the unit and makes it easier to transport. MultiLine Three Level® technology is a guarantee of stable operation even when the power supply voltage fluctuates, which is a common challenge in industrial settings and construction sites.

The SteelDrive software package on the TERRA NX 320 SMC provides up to 600 advanced Böhler Arc synergy programs, dedicated specifically to welding different grades of steel. These precisely developed synergy curves automatically select the optimal welding parameters (arc voltage, wire feed speed) based on the selected material, wire diameter and shielding gas type.

The benefit for the welder is a significant simplification and acceleration of the machine setup process, elimination of errors, and a guarantee of reproducible, high-quality welds, regardless of operator experience. Böhler Arc’s programs cover a wide range of applications, from standard structural steels to high-strength steels, ensuring optimal conditions for each welding task and minimizing the risk of welding defects.
