Böhler Welding’s patented MultiLine Three Level® inverter technology is at the heart of the TERRA NX series, including the 500 PME ROCKSTAR model. It features three-level power commutation, which translates into significantly higher energy efficiency (reduced power consumption) and excellent welding arc stability and dynamics.

Thanks to this technology, the device is more resistant to fluctuations in supply voltage and provides a faster response of the control system to changes in welding conditions. This results in better weld quality, fewer spatters and the ability to work efficiently with long welding leads without sacrificing performance. This is a direct benefit to the professional in terms of lower operating costs, greater reliability and better control over the welding process.

ArcDrive is an enhanced, digitally controlled MIG/MAG standard (short arc) welding process developed by Böhler Welding. A key feature of ArcDrive is an extremely stable and highly reactive welding arc that dynamically adjusts to changes in the length of the free wire exit or surface irregularities.

For the welder, this means easier arc guidance, especially in forced positions and when welding joints with larger gaps. The process significantly reduces the amount of weld spatter, which minimizes the time needed for weld post-treatment and reduces the cost of cleaning materials. ArcDrive is ideal for welding carbon steels, stainless steels, aluminum and cored wires, ensuring high quality and repeatable joints.

PulsDrive is a digital MIG/MAG pulse welding process from Böhler Welding that provides superior control over material transfer to the weld pool. It operates on a “one pulse – one drop” principle, which allows for precise, nearly spatter-free welding of a wide range of materials, including aluminum, stainless and high-alloy steels.

The main benefits of PulsDrive are excellent weld face quality and appearance, minimal heat introduction (which reduces distortion, especially in thin materials) and high arc control. The process is particularly effective for welding in forced positions and for creating welds with an aesthetic appearance, eliminating the need for additional machining.

RapiDeep is an innovative MIG/MAG welding process from Böhler Welding, designed to maximize fusion depth while increasing welding speed. It features a highly concentrated, stable arc that penetrates the material deeper than standard short-circuit processes.

With RapiDeep, professionals can achieve an increase in welding speed of up to 30-50% compared to conventional methods, while maintaining excellent joint quality. The process also reduces the amount of heat input (HI), which minimizes distortion and stress in the structure. RapiDeep is particularly effective for welding carbon and low-alloy steels, where high productivity and deep fusion are required.

QuickPulse is an advanced MIG/MAG pulse welding process from Böhler Welding that combines the deep penetration advantages of the RapiDeep process with the stability and quality of PulsDrive pulse welding. The result is an extremely efficient process, ideal for welding materials such as stainless steel and aluminum.

QuickPulse allows welding speeds that are up to 50% higher than traditional pulse welding, while maintaining excellent control over the weld pool and minimal heat input. This guarantees deep penetration, excellent weld appearance and reduced distortion. It is ideal for applications requiring high productivity and impeccable quality, such as in the automotive industry or in the manufacture of stainless steel structures.

The Böhler Arc system is an integrated database containing hundreds of optimized synergy programs for MIG/MAG welding. These programs are precisely tailored to different combinations of materials (carbon steel, stainless steel, aluminum, special alloys), welding wire diameters and shielding gas types.

For the professional, Böhler Arc means significantly simplifying and speeding up the process of setting welding parameters. Once the appropriate program is selected, the device automatically selects the optimal voltage, wire feed speed and other key parameters, ensuring reproducible , high quality welds from the first start. This reduces the risk of errors, reduces preparation time and allows you to focus on getting the job done accurately, resulting in higher productivity and lower production costs. The ROCKSTAR version offers the broadest suite of these programs.
