At the heart of the TERRA NX 400 PMC STEELDRIVE is Böhler Welding’s patented MultiLine Three Level® Inverter technology. This advanced system not only provides exceptional energy efficiency and operational reliability, but also instant control of the welding arc. This makes it possible to achieve a stable welding process over a wide range of parameters.

The benefits for the professional are primarily reduced energy consumption, smaller size and weight of the machine relative to its power, which facilitates mobility, and longer component life due to reduced thermal stress. This technology is the foundation for the precise and efficient welding processes offered by Böhler Welding.

ArcDrive is an enhanced, digitally controlled MIG/MAG process from Böhler Welding, designed for maximum arc stability and reactivity. It makes welding easier, especially in difficult welding positions, and significantly reduces weld spatter. This translates directly into time and cost savings in the post-processing of welded joints.

The ArcDrive process is the ideal choice for welding carbon steels, stainless steels, aluminum and cored wires, ensuring high weld quality and welder comfort. It is a standard but highly optimized technology in Böhler Welding equipment, guaranteeing excellent results.

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 materials, aluminum and stainless steels. The result is an excellent weld finish, minimal distortion and a reduced heat affected zone.

With PulsDrive, professionals can achieve aesthetically pleasing welds of reproducible quality, even in demanding applications. The process significantly simplifies welding in forced positions and minimizes the risk of welding defects such as sticking or undermelting.

Available with the STEELDRIVE package, the RapiDeep process is Böhler Welding’s innovative solution for MIG/MAG welding that revolutionizes productivity. It features deeper material penetration while reducing heat input (Low Heat Input). This allows welding speeds to be increased by up to 50% compared to standard methods.

RapiDeep is particularly effective for welding structural and stainless steels, enabling faster fillet and butt welds without sacrificing quality. Reduced weld distortion and stress are additional benefits that translate into a higher quality final product and lower processing costs.

QuickPulse, available in STEELDRIVE configuration, combines the deep penetration advantages of the RapiDeep process with the precision and quality of PulsDrive pulse welding. This advanced process offers exceptionally high welding speeds, up to 50% faster than standard pulse, while maintaining excellent pond control and minimal heat introduction (Low H.I.).

QuickPulse is ideal for welding steel and aluminum where both speed and high aesthetic quality of the weld are required. It enables deep fusion while reducing spatter and distortion, making it an excellent choice for mass production and applications requiring the highest productivity.

The STEELDRIVE package on the TERRA NX 400 PMC provides access to an expanded library of up to 600 advanced Böhler Arc synergy programs. These precisely developed synergy curves automatically optimize welding parameters (such as arc voltage, wire feed speed) depending on the selected material, wire diameter and shielding gas.

With Böhler Arc, welders can quickly and easily set the ideal parameters for a wide range of applications, which guarantees reproducible , high-quality welds and minimizes the risk of errors. This intelligent support significantly increases productivity and makes work easier even when welding complex structures and a variety of materials, including high-strength steels, stainless steels or aluminum alloys.
