TELWIN SUPERIOR 400 CE VRD is a real breakthrough in the field of power supply for professional welding machines. Thanks to the innovative design of the power supply system, the device can be connected to both three-phase 230V (±15%) and standard three-phase 400V (±15%) mains. This unique feature eliminates the problem of incompatibility of the power source in different workplaces – from modern industrial plants to older installations or specific conditions on construction sites, including abroad.

For the professional welder, this means maximum mobility and readiness to work in any conditions, without the need for additional, often heavy and expensive transformers or generators. The system automatically recognizes the input voltage and adjusts the operating parameters, ensuring full power and performance regardless of the source. This is not only a convenience, but also a real savings and increased operational efficiency, allowing you to focus on the task at hand rather than on power infrastructure problems.

Welder safety is an absolute priority, especially when working in high-risk environments such as damp rooms, tight metal spaces (tanks, pipelines) or working outside in the rain. The TELWIN SUPERIOR 400 CE VRD is equipped with an advanced VRD (Voltage Reduction Device) system that significantly minimizes the risk of electric shock.

VRD technology works by automatically lowering the idle voltage (the voltage at the electrode holder when the welding arc is not engaged) to below 25V. This is a value considered safe under most conditions. This function activates immediately when welding is interrupted and remains active until the arc is re-ignited. This protects the welder from dangerous voltages, which can be as high as 70-90V in standard welders. The ability to enable/disable the VRD function gives the user full control and allows the device to be tailored to specific work requirements and health and safety regulations.

When a project requires welding thick steel components, large-diameter pipelines or heavy support structures, you need a tool with uncompromising power and performance. The TELWIN SUPERIOR 400 CE VRD delivers an impressive welding current of up to 400 amperes, allowing you to work efficiently with covered electrodes up to 8 mm in diameter. Such power guarantees deep penetration and solid, durable welds that meet the highest quality standards.

But power is not everything. Equally important is the high duty cycle, which in this model reaches impressive values: 35% at a maximum current of 400A, 60% at 310A and as high as 100% at 260A (at 40°C). This means that the welder is able to work for long periods of time without cooling interruptions, which is crucial for large projects and series production. For the professional, this translates into a significant reduction in working time, increased productivity and profitability of orders. Whether you work in shipbuilding, construction or heavy fabrication, the SUPERIOR 400 CE VRD is up to the toughest challenges.

The TELWIN SUPERIOR 400 CE VRD is not only powerful, but also intelligent. An advanced microprocessor controls key MMA welding support functions such as Arc Force, Hot Start and Anti-Stick that make the job easier, faster and produce better results, even in the hands of less experienced welders.

Adjustable Hot Start ensures optimal arc ignition by delivering a pulse of current at the very beginning of welding. This is especially useful when working with difficult electrodes or on dirty surfaces. Adjustable Arc Force dynamically increases the welding current as the arc becomes shorter, preventing it from extinguishing and sticking the electrode. This allows welding with a more stable arc, even in forced positions. The Anti-Stick function, on the other hand, automatically reduces the current when the electrode sticks to the material, making it easier to detach the electrode without damaging the electrode or the material. These intelligent systems work together to ensure excellent weld quality, minimal spatter and greater comfort, resulting in professional results every time.
