TELWIN SUPERTIG 302 AC/DC: Master Level Precision in TIG and MMA Welding for Professionals
Meet the TELWIN SUPERTIG 302 AC/DC, an inverter welder that sets new standards in professional TIG welding, with high frequency HF striking or with LIFT ARC, and in MMA welding. Designed for demanding industrial and workshop use, this powerful machine running on 400V joins Italian engineering with current technology to deliver quality, output and versatility. Whether you work with carbon steel, stainless steel, titanium, copper, nickel, magnesium or special aluminium alloys, the SUPERTIG 302 AC/DC gives a clean result every time.
Imagine welding where every parameter is fully under your control and the arc answers each of your movements with surgical accuracy. The TELWIN SUPERTIG 302 AC/DC is not only a tool, it is a partner in daily work that understands what a professional needs. Thanks to welding on alternating current (AC) and direct current (DC), including the special TIG Pulse and Easy Pulse modes, you weld thin sheet without burning through, you control the heat input and you shape the weld face exactly as you want it. Compromises fall away, this welder was built to go beyond expectations.
Solutions such as microprocessor control, the wide adjustment of the TIG welding cycle (bi-level, start and end current, slope up and slope down time, AC balance, AC frequency) and the functions that support MMA welding (Arc Force, Hot Start, Anti-Stick) turn the SUPERTIG 302 AC/DC into a truly versatile welding station. It is an investment that pays back quickly, the work gets more efficient, the finishing of the beads is reduced and the joints stay durable.
The SUPERTIG 302 AC/DC + ACC. model, catalogue number 816245, is supplied with the accessories needed to start work at once. Choosing Telwin means decades of experience, reliability and technical support at a high level. Raise the quality of your services and gain an edge with technology you can rely on.
A Closer Look at the TELWIN SUPERTIG 302 AC/DC 400V + ACC.
Precise Arc Control in TIG AC Welding of Aluminium
Welding aluminium with TIG AC calls for special control of the arc, so that the oxide layer is broken up reliably and the penetration stays right. The TELWIN SUPERTIG 302 AC/DC offers advanced functions made for that task. The key one is AC current balance adjustment, which sets the ratio between the positive half wave (cleaning) and the negative half wave (penetration) precisely. The welder can tune the process, obtain a clean and bright bead with good fusion and at the same time limit the wear of the tungsten electrode.
The second important parameter is AC frequency adjustment. A higher frequency gives a narrower and more concentrated arc, which helps on thin aluminium sheet and on fillet welds where accuracy decides. The SUPERTIG 302 AC/DC allows smooth setting of this frequency and gives the welder full control over the arc and the weld pool. Together with the TIG Pulse function in AC mode, very good results are within reach even on the most demanding aluminium alloys.
Intelligent TIG Functions for Consistent Quality
The TELWIN SUPERTIG 302 AC/DC carries a set of intelligent TIG functions that speed up the work and raise the quality of the joints. Besides the standard settings such as gas flow adjustment before and after welding (pre-gas, post-gas), which protect the weld pool and the electrode against oxidation, the unit offers full control of the welding cycle. Setting the start current, the slope-up time, the welding current, the crater current, the slope-down time and the end current makes it possible to begin and finish the bead cleanly, without defects such as cracks or craters.
The Bi-Level function switches quickly between two welding current levels with a button on the torch, which is very useful when the material thickness changes or when the welding position changes without breaking the arc. On top of that, the advanced TIG Pulse mode, with adjustable pulse frequency, base current and pulse duty ratio, allows precise control of the arc energy. The result is a smaller heat affected zone, less distortion of the material and neat rippled beads that are valued above all on stainless steel.
Reliability and Safety in Professional Use
The TELWIN SUPERTIG 302 AC/DC was designed for intensive use in industrial conditions. The solid construction and good quality components give a long service life and reliability. The unit carries a set of thermal and overvoltage protections that keep it from damage in case of overload or an unstable supply network. The cooling system with an efficient fan that starts when needed keeps the internal parts in good working conditions even during long welding at high current.
The welder also offers functions that raise safety and comfort at work. Contactless HF striking removes the need to touch the electrode to the material, which lowers the risk of contaminating the bead and the electrode. In MMA welding, Hot Start makes striking easier through a short rise in current, Arc Force stabilises the arc and keeps it from going out, and Anti-Stick prevents the electrode from sticking to the material. These solutions make the work easier and also add to its safety and efficiency.
Versatile Use: From the Workshop to Industry
With a broad welding current setting range, work in AC and DC mode and advanced TIG and MMA functions, the TELWIN SUPERTIG 302 AC/DC is a very versatile tool. It performs well in the automotive trade on repairs and modifications of aluminium bodywork and of stainless steel exhaust systems. In the food and chemical industry it welds pipelines and tanks made of acid resistant steel precisely, where smooth and clean beads decide.
In steel and aluminium structures this welder produces solid and neat joints, both in the workshop and on site, provided a suitable power supply is available. It is also an excellent tool for craftsmen and artists who work with metals and carry out complicated projects with the highest accuracy. Whether you deal with production, service or maintenance, the SUPERTIG 302 AC/DC delivers the power and the control the task requires.

Key Features and Benefits
- Versatile TIG AC/DC Welding with Full Parameter Control: The unit welds on direct current (DC), which suits steel, stainless steel, copper and titanium, and on alternating current (AC) with precise balance and frequency adjustment, which is the key to welding aluminium and magnesium and gives effective oxide cleaning and deep penetration. The professional can weld practically any material with the right settings, which shows in beads of the highest quality, minimal spatter and a very good looking weld face.
- Advanced TIG Pulse and Easy Pulse Modes: The TIG Pulse function, with adjustable frequency, base current and peak current, gives precise control over the heat input, which is invaluable on thin material and lowers the risk of distortion and burn through. The Easy Pulse mode simplifies the settings and picks the pulse parameters automatically. For the welder that means even and neat beads are easier to obtain, above all on heat sensitive materials, and the weld pool stays under better control in constrained positions.
- Microprocessor Control for Reliability and Repeatability: The built in microprocessor monitors and adjusts the welding parameters in real time, which keeps the arc stable and the results repeatable. The control algorithms match the arc characteristic to the different methods and materials. That gives confidence that every joint is made to the set parameters, which is critical in series production and in work that requires certification.
- Efficient MMA Welding with Support Functions: The SUPERTIG 302 AC/DC is also a very good stick welder (MMA) with adjustable Arc Force (arc dynamics), Hot Start (easier electrode striking) and Anti-Stick (no electrode sticking). Welding with covered electrodes (rutile, basic, cellulosic) runs smoothly, steadily and efficiently even in difficult conditions. The professional will value the simple operation and the quick change to another method, which makes the machine even more universal.
- Three-phase 400V Supply for Maximum Power and Stability: Running on a three-phase supply gives better arc stability and higher welding currents with better energy efficiency than single-phase units. This is decisive in industrial use, where continuous work at high power is required. It means dependable operation even under heavy use and the ability to weld thicker material without a drop in output.
- HF and LIFT ARC Arc Striking: You can choose between contactless high frequency (HF) striking and contact LIFT ARC striking. HF suits precise work and removes the risk of tungsten in the bead, while LIFT ARC is preferred in environments that react to electromagnetic interference. This freedom lets you match the striking method to the task and the working conditions, so the process always starts as it should.
