TELWIN SUPERIOR 320 CE VRD is the quintessence of modern welding technology. At the heart of the device is an advanced inverter module that converts mains current into high-frequency direct current, ideal for welding. But that’s just the beginning. The entire process is managed by a dedicated microprocessor, which monitors and corrects arc parameters in real time.

As a result, the welder offers arc stability and dynamics unattainable for traditional transformers. Regardless of fluctuations in the supply voltage or the length of the welding wires used, the SUPERIOR 320 maintains the set parameters, resulting in a uniform and high-quality weld. The microprocessor-based control also allows precise implementation of booster functions such as Arc Force and Hot Start, adjusting their operation to suit current needs. For the professional, this means less time spent on adjustments, reduced spatter, easier welding in forced positions and the certainty of obtaining welds with excellent mechanical properties.

Operator safety is a top priority, especially in the welding industry, where work often takes place in demanding and potentially dangerous conditions. The TELWIN SUPERIOR 320 CE VRD is equipped with an advanced Voltage Reduction Device (VRD) system, which significantly increases the level of protection against electric shock.

How it works. When the welding arc is not struck (e.g. during electrode changes or interruptions), the VRD system automatically reduces the voltage at the output terminals to below 25V. This voltage is considered safe for human use, even for direct contact in humid environments. This feature is invaluable when working in tanks, pipelines, ships, oil rigs or other high-risk areas. Importantly, the VRD system on this model can be activated or deactivated by the user, giving flexibility depending on the specific job and local health and safety regulations. By investing in a SUPERIOR 320 with VRD, you are investing in peace of mind and safety for yourself and your employees.

One of the most valued features of the TELWIN SUPERIOR 320 CE VRD welder by professionals is its ability to operate with two different supply voltages: single-phase 230V and three-phase 400V. This versatility opens up a wide range of operational possibilities for the user, eliminating the problem of mismatching equipment with the available power infrastructure.

Connected to a 400V three-phase mains, the welder unleashes its full potential, offering a maximum welding current of up to 280A. This is ideal for heavy construction work, welding thick parts and completing projects that require high productivity. On the other hand, its ability to be powered from a single-phase 230V outlet (with up to 200A) makes it an extremely mobile tool. You can take it to an assembly, to a customer who only has a standard installation, or use it in a home workshop. The device automatically recognizes the type of power supply, which simplifies operation and protects against errors. This flexibility is a real time and money saver, eliminating the need to own many different welding machines.

MMA (shielded electrode) welding remains one of the most popular techniques, but mastering it to perfection requires not only skill, but also the right equipment. The TELWIN SUPERIOR 320 CE VRD is equipped with a synergistic set of advanced features that take MMA welding to a new level.

Adjustable Arc Force (arc dynamics) is your personal assistant during welding. At critical moments, when the arc shortens dangerously close to the weld pool, the system automatically boosts the current, preventing the electrode from sticking and extinguishing the arc. This is crucial when welding in difficult positions and using alkaline electrodes. An adjustable Hot Start provides an extra boost of current at the very beginning, making it easier to strike the arc, even with cold material or wet electrodes. Forget about frustrating start attempts! Anti-Stick, on the other hand, is a safety and convenience feature – if the electrode sticks, however, the system immediately lowers the current, protecting the electrode from damage and allowing easy detachment. These three technologies, finely tuned by a microprocessor, translate into smooth operation, fewer weld defects and greater satisfaction with each completed joint.
