Advanced Capabilities of the TELWIN SUPERTIG 302 AC/DC 400V AQUA
Sound Welds on Aluminium Thanks to Advanced TIG AC
Welding aluminium and its alloys calls for precise control of the alternating current (AC), and the TELWIN SUPERTIG 302 AC/DC AQUA is a master in this field. The key role belongs to the AC current balance adjustment. It lets you set the exact ratio between the positive half wave (responsible for cathodic cleaning, that is removing the oxides from the aluminium surface) and the negative half wave (which gives deep penetration). The welder can therefore obtain a perfectly clean weld with the right penetration and keep the risk of defects to a minimum.
Another important parameter is the AC frequency adjustment. Higher frequencies (up to 200 Hz and more) give a more concentrated and stable arc, which is very useful when welding thin sheet, making fillet welds or working in places that are hard to reach. The result is a narrower heat affected zone, less distortion of the material and a better looking weld face. The SUPERTIG 302 gives you the tools to produce aluminium welds of a quality that matches the best industrial standards.
Reliability and Extreme Output Thanks to AQUA Water Cooling
Intensive TIG welding, above all at the high currents needed to join thicker materials, produces a lot of heat in the welding torch. The integrated, high output AQUA water cooling system in the SUPERTIG 302 is the answer to this challenge. The cooling unit (G.R.A. - Gruppo Raffreddamento Acqua) actively circulates coolant through a purpose built TIG torch and holds its temperature at the right level.
For a professional this means several concrete benefits. First, a much longer duty cycle at maximum settings, so you can weld longer without stopping to let the torch cool down. Second, greater working comfort, because the torch handle stays cool, which reduces fatigue and allows better precision. Third, a longer service life of the torch itself and of its consumables, which means lower running costs. The AQUA system is your guarantee of reliability and full readiness for work even in the hardest conditions.
Full Control and Repeatability Thanks to Advanced TIG Functions
The TELWIN SUPERTIG 302 AC/DC AQUA is not only power, it is above all intelligent control of the welding process. The machine offers a rich set of advanced TIG functions that let you adapt every aspect of the welding arc to the task in hand. The TIG Pulse function is invaluable when welding thin materials, stainless steel or nickel alloys. It allows precise control of the heat input, keeps distortion and the risk of burn through to a minimum and also gives the weld its characteristic, attractive look. Adjustment of the pulse frequency, the pulse balance and the peak and base current gives the welder full flexibility.
In addition, functions such as slope-up and slope-down current time control give a gentle start and finish to the weld and remove craters and defects at the ends of the run. Precise setting of the gas pre-flow (pre-gas) and post-flow (post-gas) times guarantees the best protection of the weld pool and of the tungsten electrode against oxidation. The Bi-Level function lets you switch quickly between two set welding current levels during work, which is very useful when the material thickness changes. All these options, reached through an intuitive panel, give outstanding control and repeatability, which is the key to professional work.

Key Features and Benefits
- AC/DC Welding Flexibility with Advanced Adjustment: The SUPERTIG 302 offers the full scope of welding with alternating current (AC), ideal for aluminium and magnesium, with precise control of the wave balance (cleaning versus penetration) and of the AC frequency (arc concentration). Direct current (DC) gives excellent results when welding carbon and stainless steels, copper, nickel, titanium and their alloys. The professional gets a universal tool for the most varied projects, from delicate work on thin aluminium sheet to welding load bearing steel structures, always with the right parameters and the best weld quality.
- Integrated AQUA Water Cooling System: The high output liquid cooling unit for the welding torch (G.R.A.) is the key element that keeps work going at high currents and in long cycles. The system actively lowers the temperature of the TIG torch, which directly extends its service life, greatly increases the welder's comfort by removing the overheating of the handle and allows work at full power for longer without any risk of damaging the equipment. That is a guarantee of maximum productivity, above all in industrial conditions.
- Intuitive Control Panel with a Microprocessor: The advanced yet simple digital panel with an LCD display allows precise setting and monitoring of all the key TIG and MMA welding parameters. It covers among others: initial current, welding current, base current, final current, slope up and slope down times, pulse parameters (frequency, balance, peak current), AC balance and frequency, gas pre-flow and post-flow times (pre-gas/post-gas). For the welder this means full control over the weld pool, repeatable settings and the option to match the arc characteristic to every task, which is essential for welds of the highest quality.
- Dynamic Welding Support Functions (TIG Pulse, THINSPOT, MMA Arc Control): The machine carries advanced functions such as TIG Pulse (for better heat control, welding of thin materials and attractive welds), the THINSPOT function for fast and precise spot welding and a complete set of MMA functions: Arc Force (arc stabilisation and penetration control), Hot Start (easy electrode ignition) and Anti-Stick (prevents the electrode sticking). These technologies make the work considerably easier, reduce the risk of mistakes and give excellent results even in difficult conditions and on demanding materials, shortening the time a task takes.
- Solid Construction and Professional Protections: The SUPERTIG 302 was built for intensive use in an industrial setting. A solid housing, high quality components and an integrated transport trolley give durability and mobility. The machine carries a complete protection system: thermostatic, overvoltage, undervoltage, overcurrent and protection against overload of the pump in the cooling circuit. That guarantees safe, long and trouble free work and protects both the welder and the operator.
