Böhler Welding’s patented MultiLine Three Level® inverter technology is at the heart of the TERRA NX 320 PMC. It not only provides exceptional energy efficiency and reliability, but also enables instant control of the welding arc. This results in a reduction in the size and weight of the unit while increasing its performance. For the professional, this means lower energy bills, greater mobility and a stable, easy-to-control arc, which is key to achieving the highest quality welds.

ArcDrive is an improved fundamental MIG/MAG process from Böhler Welding, featuring an extremely stable and dynamically responsive welding arc. This feature significantly facilitates welding, especially in forced positions and when welding materials of varying thickness. A key benefit for the welder is a significant reduction in spatter, which minimizes the need for time-consuming post-processing and reduces material costs. ArcDrive is ideal for welding carbon steels, stainless steels, aluminum and cored wires, providing a smooth and clean weld face.

PulsDrive is a digitally controlled MIG/MAG pulse welding process that operates on the principle of “one pulse – one drop.” It provides excellent control over the transfer of material into the weld pool, resulting in exceptional weld quality and an aesthetic finish, similar to the TIG method. The process minimizes the amount of heat input, reducing material distortion, which is especially important when welding thin sheet metal and materials sensitive to overheating, such as aluminum and stainless steels. PulsDrive is a guarantee of precision and repeatability, even for the most demanding applications.

QuickPulse is an innovative pulsed process that combines the advantages of deep penetration with high welding speed. Compared to standard pulse welding, QuickPulse can increase welding speed by up to 50% while providing deeper penetration and lower heat input (Low Heat Input). The result is higher productivity, less distortion of welded parts and excellent joint quality, especially when welding thicker sections of steel and aluminum. QuickPulse is the ideal solution for professionals seeking to maximize productivity without compromising on quality.

The Böhler Arc system is an integrated library of synergy programs that significantly simplifies the process of setting welding parameters. After selecting the type of material, wire diameter and shielding gas, the device automatically selects the optimal welding parameters, guaranteeing excellent results from the first use. The professional gains time savings, reduced risk of errors and reproducibility of high-quality welds, regardless of the operator’s experience. The Böhler Arc in TERRA NX 320 PMC covers a wide range of materials and applications, making the device extremely versatile.

The Dual Pulse function of the TERRA NX 320 PMC produces welds with an extremely aesthetic appearance, reminiscent of a TIG weld scale. This process modulates the welding current with two pulse frequencies, which provides better control over the shape of the weld pool and the appearance of the weld face. This is particularly beneficial when welding aluminum and stainless steel, where the aesthetics of the joint are crucial. Dual Pulse minimizes spatter, facilitates welding of thin materials and provides excellent visual results, enhancing the quality of the final product.
