At the heart of the TERRA 150 welder is advanced inverter technology, developed and refined by Böhler Welding engineers. It ensures not only a significant reduction in the weight and dimensions of the device compared to traditional transformer sources, but above all precise control of the welding arc parameters. This results in a stable arc glow, fewer spatters and excellent weld quality when welding with various types of covered electrodes.

Thanks to its high energy efficiency, inverter technology minimizes power consumption, which translates into lower operating costs. Professionals will also appreciate the source’s fast dynamic response, which is crucial when welding in difficult positions and under varying operating conditions. This is the foundation on which the performance and reliability of the TERRA series is based.

The Böhler TERRA 150 is equipped with a suite of integrated features to support the MMA welding process, which significantly simplify the work and improve the quality of the connections made.
* Hot Start: Automatically increases the welding current at the beginning of the process, which guarantees a safe and easy arc strike even with wet or difficult to strike electrodes. This eliminates the risk of electrode sticking and initial weld defects.
* Arc Force (Arc Dynamics): Dynamically adjusts the welding current according to the arc length, preventing the arc from going out and stabilizing the electrode melting process. It enables welding with a short arc for better control of the weld pool and deeper fusion, especially when welding in forced positions.
* Anti-sticking: In the event of a short circuit (sticking of the electrode to the material), this function automatically reduces the welding current to a minimum, allowing the electrode to be easily detached without damage or overheating. This protects both the electrode and the device itself.

These synergistic features make MMA welding more intuitive, more efficient and produce welds with excellent strength and aesthetic performance, even for welders with less experience.

The Böhler TERRA 150 welder offers the added functionality of basic DC TIG welding with Lift ignition (LIFT TIG). This method is ideal for precision joining of carbon steels, low-alloy steels and stainless steels, where high weld quality and aesthetics and minimal heat introduction are required.

Lift-Arc ignition eliminates the risk of tungsten contamination of the weld and reduces electromagnetic interference, unlike the HF method. This process requires the purchase of a suitable TIG holder with a gas valve. TERRA 150 provides a stable DC current, which allows for smooth and clean welds, ideal for applications in the food industry, chemical industry, balustrades or decorative elements. This feature significantly expands the range of possible work performed with a single, compact unit.
