Böhler Welding’s (Selco) patented MultiLine Three Level® inverter technology is at the heart of the TERRA NX 320 PME. It not only provides exceptional energy efficiency and reliability, but also instant response and precise control of the welding arc. This results in a significant reduction in size and weight of the power source while increasing its power and operating stability, which is crucial in demanding industrial environments. The benefit to the professional is a more stable arc, lower power consumption and longer equipment life.

ArcDrive is a fundamental improved MIG/MAG process from Böhler Welding that redefines arc stability. It features a highly reactive and focused arc, which significantly facilitates welding, especially in forced positions and when welding thin materials. A key benefit is the drastic reduction in weld spatter, minimizing the need for time-consuming post-processing by up to 30-40%. ArcDrive is ideal for welding carbon steel, stainless steel, aluminum and cored wires, providing cleaner and smoother welds.

PulsDrive is a digitally controlled MIG/MAG pulse welding process, where each pulse of current is precisely responsible for tearing off one drop of metal (“one pulse – one drop”). This provides unparalleled control of the arc and weld pool, which is especially important when welding thin sheet metal and heat-sensitive materials such as aluminum or stainless steel. The result is excellent weld finish, minimal distortion and deeper penetration with reduced heat input. Professionals value PulsDrive for its aesthetics and joint quality.

RapiDeep is an innovative MIG/MAG process developed by Böhler Welding, designed to maximize welding speed and penetration depth. Thanks to its specially shaped, concentrated arc, RapiDeep allows an increase in welding speed of up to 50% compared to standard MIG/MAG methods, while achieving deeper penetration. In addition, the process features less heat input (HI), which minimizes the risk of material distortion. Ideal for efficient welding of thicker sections of carbon and stainless steels.

QuickPulse is an advanced pulse welding process that combines the advantages of the deep penetration characteristic of RapiDeep with the precision and finish quality of PulsDrive. It offers significantly higher welding speeds (up to 50% faster than standard pulse), with excellent arc control and minimal heat input (low H.I.). QuickPulse provides deep penetration and is ideal for welding aluminum and stainless steel, where both speed and impeccable weld quality are important. This process is available as an option for the TERRA NX PME series.

CladPulse is a specially developed pulsed process by Böhler Welding for surfacing (cladding). Its key feature is to ensure very low dilution of the parent material with the surfacing, which is critical for maintaining the desired properties of the surfaced layer. The process is characterized by a soft, stable arc and high deposition efficiency. CladPulse makes it possible to achieve the required mechanical and corrosion properties often in just one layer, significantly reducing the cost and time of surfacing operations. It is an optionally available process for the TERRA NX PME series.

The Böhler Arc system is a collection of advanced synergy programs that automatically select the optimal welding parameters based on the selected material, wire diameter and shielding gas. For the professional, this means a significant simplification and acceleration of the welder setup process, elimination of errors and a guarantee of reproducible, high-quality welds. Böhler Arc’s TERRA NX PME provides access to a wide range of synergy curves optimized for various applications, including welding steel, stainless steel and aluminum, also using Double Pulse for even better control and weld aesthetics.
