Get to Know the Advanced Options of the TELWIN SUPERTIG 302 AC/DC 400V AQUA + TROLLEY
Perfect Aluminium Welding: The Secrets of TIG AC Mode
Welding aluminium with the TIG AC method requires precise control over the arc parameters in order to remove the oxide layer effectively and obtain deep penetration. The TELWIN SUPERTIG 302 AC/DC offers advanced options here. The key function is AC balance adjustment, which lets you set the proportion between the duration of the positive half wave (cleaning) and the negative one (penetration). You can therefore optimise the process both for clean and for more contaminated surfaces and obtain a perfectly clean and durable weld.
Another important parameter is AC frequency adjustment (usually in the range of 20-200 Hz). A higher frequency gives a narrower and more concentrated arc, which is ideal for the precise welding of thin sheet and minimises the heat affected zone and distortion. Lower frequencies generate a wider arc, useful when welding thicker parts or filling larger gaps. The SUPERTIG 302 gives you full freedom in shaping the arc, which translates into welds of the highest quality, free of porosity and structural defects, even with the most demanding aluminium alloys.
Intelligent TIG Pulse: Heat Control and Weld Appearance
The TIG pulse welding function in the SUPERTIG 302 is a powerful tool in the hands of a professional. It allows cyclic changes of the welding current between the peak current and the base current, with adjustable frequency and pulse duty ratio. Pulsed welding considerably reduces the amount of heat put into the material, which is exceptionally important when joining thin sheet, stainless steel and materials sensitive to overheating. This lets you avoid burn through, distortion and the loss of corrosion properties, for example in austenitic steels.
Thanks to precise control of the pulse parameters, the welder can obtain welds with an excellent appearance and the characteristic, regular scale pattern, which is often an appearance requirement. What is more, pulsing the arc improves control over the weld pool and makes welding in constrained positions easier. The available EASY PULSE function selects the best pulse parameters automatically, which is a great help especially for less experienced users, while guaranteeing high quality of the joint.
AQUA Cooling and the TROLLEY: Comfort and Output Non-Stop
Intensive welding work, especially at high TIG currents, generates a considerable amount of heat in the welding torch. The TELWIN SUPERTIG 302 in a set with the AQUA liquid cooling module (G.R.A.) removes this problem. The system actively circulates coolant through a specially designed torch and keeps its temperature at the optimal level. The main benefits are a drastic increase in the duty cycle of the welder at maximum loads, you can weld longer without breaks to cool the torch. This translates directly into higher productivity and efficiency in your work.
The ergonomic TROLLEY AMERICA is not only convenient for transport. It was designed to hold the welder, the cooling unit, the shielding gas cylinder and the necessary accessories such as cables and torches. The whole welding station is therefore mobile, orderly and safe. No more tangled cables and carrying heavy equipment, with the SUPERTIG 302 AQUA + TROLLEY you have everything at hand, ready for work in any place. This is an investment in comfort that genuinely affects the quality and the pace of the work.
Advanced MMA Functions: Strength and Reliability in Every Electrode
Although the SUPERTIG 302 AC/DC is a master of TIG welding, its options in the MMA method (stick electrode) are equally impressive and offer a welding current up to 250A. The machine has a set of functions that make this process easier and better. The adjustable Arc Force function dynamically increases the welding current at the moment the arc shortens, which prevents it from going out and stops the electrode sticking, and is especially useful when welding in difficult positions and with electrodes for special purposes.
The Hot Start function gives a brief increase of current at the start of welding and makes arc ignition easier, even with cold or damp electrodes. The Anti-Stick system in turn reduces the current automatically if the electrode sticks to the material and lets you free it easily without damage. These intelligent aids make MMA welding smoother, more efficient and available even to people with less experience, while guaranteeing strong and durable joints in various types of steel.

Key Features and Benefits
- Versatile TIG AC/DC Welding with Full Adjustment: The ability to weld with alternating current (AC) suits aluminium and magnesium perfectly and gives effective oxide cleaning and a stable arc thanks to AC balance and frequency adjustment. Direct current (DC) guarantees precise and clean welds in stainless steel, carbon steel, copper, titanium and other metals. Full control over the parameters, including pulsed current (standard and EASY PULSE), allows the welding of very thin as well as thick materials and minimises distortion and heat input, which translates into excellent quality and appearance of the welds and savings on filler metal.
- Integrated AQUA Liquid Cooling System: The G.R.A. cooling module effectively lowers the temperature of the TIG welding torch, which matters most when working at high currents and in long welding cycles. For a professional this means the ability to work without interruption and without the risk of overheating the torch, a considerably longer duty cycle of the machine (for example 200A at 100% for TIG), greater comfort in welding and a longer service life of the torch consumables. The result is higher productivity and lower operating costs.
- Advanced Microprocessor Control and Special Functions: The microprocessor manages all the welding parameters and gives the best conditions for the arc. Functions such as Bi-Level (switching between two current levels during welding), THINSPOT (fast and precise spot welding), arc dynamics adjustment (Arc Force), Hot Start (easy ignition of the MMA electrode) and Anti-Stick (prevention of electrode sticking) make the work considerably easier and raise its quality. That means fewer corrections, faster completion of tasks and welds of repeatable, high quality.
- Solid Construction and Mobility with the TROLLEY: The SUPERTIG 302 was built for difficult industrial conditions, which guarantees its durability and reliability. The TROLLEY AMERICA included in the set not only makes it easier to transport the welder together with the cooling unit and a heavy gas cylinder, but also keeps the work station tidy, with a place for accessories and cables. For the welder this means greater flexibility, safety and ergonomics in work, both in the workshop and on site.
- Clear Control Panel and Remote Control Option: The intuitive control panel with a digital display allows precise setting of all welding parameters and easy reading of them. The option of connecting a remote control (a foot pedal or a controller in the handle) allows smooth adjustment of the current during welding without taking your hands off the work. That is the key to perfect welds in difficult positions and on complex details, and it increases the comfort and precision of the operator.
- Efficient Stick Electrode Welding (MMA): Besides the advanced TIG functions, the machine also offers excellent parameters for MMA welding with a current up to 250A. The adjustable Arc Force and Hot Start functions and the Anti-Stick system give a stable arc and easy ignition for various types of electrode (rutile, basic, cellulosic, stainless, cast iron). That makes the SUPERTIG 302 a genuinely universal tool, ready for every welding challenge.
