The TELWIN SUPERIOR TIG 311 DC puts in the hands of the professional an arsenal of tools for precise arc shaping and TIG welding parameters. Microprocessor control, which manages the entire cycle, plays a key role. The PULS TIG function, including a simplified EASY PULS mode, allows welding of very thin materials with minimal heat input to prevent burn-through and deformation, and to produce an aesthetically pleasing, scaly weld.

The user can fine-tune such parameters as pulse frequency, base and peak current, and pulse balance, allowing the arc characteristics to be perfectly matched to the type of material and thickness. The Bi-Level function allows you to switch between two levels of welding current during operation, which is invaluable when welding parts of varying thickness or when temperature control is required. In addition, full control over the pre-gas and post-gas timing of the shielding gas (Pre-Gas, Post-Gas), as well as the time of the current rise (Slope-Up) and fall (Slope-Down), guarantees a clean start and finish of the weld without porosity or craters. All of this translates into the highest quality welds, meeting stringent standards.

One of the biggest advantages of the SUPERIOR TIG 311 DC welder is its ability to work with both single-phase 230V and three-phase 400V power. The device automatically detects the type of voltage connected, eliminating the need for manual setup and the risk of confusion. This feature makes it an extremely versatile tool, ideal for professionals working in a variety of locations.

In a workshop setting, connecting to a 400V power supply allows the machine to use its full power (up to 300A for TIG) and achieve higher duty cycles, which is crucial for welding thicker materials and completing long-lasting tasks. And the ability to operate on 230V power (up to 220A for TIG) opens the door to field assembly work, on-site repairs, or in areas with limited power infrastructure. Regardless of the power source, TELWIN’s advanced electronics ensure a stable and powerful arc, guaranteeing repeatability and high quality welds. It’s an investment in independence and ready to take on any challenge.

TELWIN SUPERIOR TIG 311 DC is not only a master of precision in the TIG method, but also a powerful and reliable tool for shielded electrode welding (MMA). Equipped with a number of functions to support the MMA welding process, it significantly facilitates the work and improves the quality of the obtained connections. The Arc Force (arc dynamics) function automatically increases the welding current when the arc is shortened, preventing it from extinguishing and sticking the electrode, which is particularly useful for welding in forced positions and hard-to-reach places.

Hot Start provides a momentary increase in welding current at the beginning of the process, making it easier to ignite the electrode, especially when working with difficult-to-ignite electrode types or on cold material. The Anti-Stick function, on the other hand, automatically reduces the welding current if the electrode sticks to the material, preventing overheating and making it easier to detach. These intelligent systems, combined with the high welding current (up to 250A at 400V), make the SUPERIOR TIG 311 DC an excellent choice for a wide range of MMA work, from lightweight construction to more demanding industrial applications, guaranteeing strong and durable welds.

For a professional, it is not only the quality of the weld that matters, but also the efficiency and comfort of work. The TELWIN SUPERIOR TIG 311 DC meets these expectations by offering the ability to save up to 9 individual welding programs (JOBs function). This allows the welder to quickly recall optimized settings for frequently performed, repetitive tasks, saving time and minimizing the risk of errors. This is especially valuable when working with different materials and thicknesses, where fine-tuning the parameters is crucial.

The unit is also equipped with a number of safety features, such as thermostatic, overvoltage (to protect against power surges from the generator), undervoltage and overcurrent. The Voltage Reduction Device (VRD) function reduces the idle voltage to a safe level when the machine is not welding in MMA mode, which increases operator safety, especially in environments with high humidity or where health and safety regulations require it. These intelligent solutions demonstrate TELWIN’s attention to equipment reliability and user safety, allowing you to focus on getting the job done perfectly.
