TELWIN SUPERTIG 302 AC/DC 400V: professional power and TIG welding precision for the most demanding jobs
Meet the TELWIN SUPERTIG 302 AC/DC 400V, an advanced TIG and MMA power source built for professionals who expect uncompromising quality, reliability and full control over the welding process. This technically advanced machine answers the needs of demanding production shops, steel fabricators and craftsmen working with stainless steel, aluminium, titanium, copper and their alloys. The SUPERTIG 302 lifts the usual equipment limits and lets you carry out even complicated welding projects with fine precision.
Picture welding aluminium with a perfectly clean and smooth bead, thanks to detailed control of the AC current parameters, balance and frequency included. Think of flawless root fusion in thin stainless steel sheet, reached with a stable arc and precise TIG DC pulse welding. The TELWIN SUPERTIG 302 AC/DC is not only a tool, it is your partner on the way to mastery. Microprocessor control, a clear panel and a broad adjustment range make every operation simpler, faster and more effective.
Investing in the SUPERTIG 302 means investing in the future of your workshop. Solid construction, high quality components and the standing of the TELWIN brand support long, trouble-free operation even in hard industrial conditions. The unit was designed for intensive use, holding parameters repeatably and keeping weld quality steady. Whether you work on precise details or run large structural projects, the SUPERTIG 302 gives you the power and the control you need.
No more trade-offs between versatility and specialisation. This model covers the full span of TIG welding (LIFT striking and contactless HF striking) with direct current (DC) and alternating current (AC) plus a pulse option, and welding with covered electrodes (MMA) on direct current. One machine therefore handles everything from delicate work on thin material to welding thick structural parts, which makes it an economical and versatile answer for any professional.
Explore the advanced capabilities of the TELWIN SUPERTIG 302 AC/DC 400V
Perfect welds on aluminium thanks to advanced AC control
TIG AC welding of aluminium calls for unusual precision and control of the arc parameters, and the TELWIN SUPERTIG 302 AC/DC supplies the tools to meet that. The key role belongs to AC balance adjustment, which sets the exact proportion between the positive half-wave, responsible for cleaning oxides from the aluminium surface, and the negative half-wave, which gives deeper penetration. The welder can therefore obtain a perfectly clean bead free of contamination while controlling penetration and reducing the risk of undercut or lack of fusion.
The next important parameter is AC frequency adjustment. Higher frequencies (up to 200 Hz or more, depending on the exact specification of this model) give a more concentrated and stable arc, which means a narrower bead, a smaller heat affected zone and better control of the weld pool, above all on thin aluminium sheet and in corners. Because these parameters can be adapted, the SUPERTIG 302 is a fitting tool for welding bicycle frames, tanks, car body parts, aluminium structures and many other applications that call for the highest joint quality.
Precise heat control with TIG pulse for stainless steel and thin material
The TIG pulse welding function in the SUPERTIG 302 AC/DC is a real change for professionals working with stainless steel, thin sheet and materials sensitive to distortion. The advanced pulse mode offers full control over parameters such as pulse frequency, pulse balance (the duration of the peak current against the base current) and the peak and base current values. Heat input into the material can therefore be dosed precisely.
Thanks to pulsing, the welder can produce very neat beads with the typical stacked pattern while keeping heat input low. The result is a clear reduction of material distortion, which is decisive when welding thin parts, for example in the food and pharmaceutical industry or in decorative stainless steel work. Pulsing also improves control of the weld pool in difficult positions, helps to reach full penetration in single sided welding and keeps the bead clean, cutting the risk of overheating and oxidation. The Easy Puls function further simplifies the settings for less experienced users by selecting suitable parameters automatically.
Industrial reliability and ergonomics for maximum output
The TELWIN SUPERTIG 302 AC/DC was designed for intensive use in demanding industrial settings. A solid metal housing protects the internal components against mechanical damage, and the IP23 protection rating gives resistance to dust and splashing. The unit carries numerous protections, thermal, overvoltage, undervoltage and overload among them, which supports safe work and a long service life of the welder.
To keep working conditions right when welding at high currents, the SUPERTIG 302 is prepared for use with a liquid cooling unit (for example the Telwin G.R.A.). That allows lighter and more ergonomic water-cooled TIG torches, which clearly raises operator comfort during long jobs, reduces fatigue and improves precision. An intuitive control panel with digital displays and legible pictograms gives quick access to all functions and precise setting, which shortens set-up time and lets you focus on the welding itself, for maximum efficiency and productivity.

Key features and benefits
- AC/DC welding versatility with full adjustment: The SUPERTIG 302 welds in TIG with alternating current (AC) on aluminium and its alloys and with direct current (DC) on steel, stainless steel, titanium, copper and bronze. Full adjustment of the AC parameters, such as balance (affecting cleaning and penetration) and frequency (arc concentration), allows the arc characteristic to be matched to the task in hand. For a professional this means work on many materials with a single unit, excellent weld quality on aluminium with optimal fusion and minimal porosity risk, and full control over the process.
- Advanced TIG pulse welding (Puls & Easy Puls): The unit carries the TIG pulse welding function, both in the standard mode (Puls) with adjustment of frequency, balance and base current, and in the simplified mode (Easy Puls). Pulsing allows precise control of the heat put into the joint, which is decisive when welding thin materials, stainless steel and materials sensitive to overheating. The benefit for the welder is neat, even beads with minimal distortion, better control of the weld pool, above all in constrained positions, and the ability to weld very thin parts without burn-through.
- High power and a professional duty cycle: Three-phase 400V supply and a maximum welding current of 280A in TIG and 250A in MMA, combined with a solid duty cycle (for example 280A @ 30% in TIG), make the SUPERTIG 302 a tool ready for intensive work in industrial conditions. It keeps welding going on demanding jobs without the risk of overheating and stoppages. For a professional this means higher output, the ability to run large projects and the certainty that the unit will handle the heaviest tasks.
- Microprocessor control and an intuitive panel: An advanced microprocessor controls all welding parameters and keeps them stable and repeatable. The legible control panel with digital displays makes precise setting of every function easy, welding current, slope up and slope down times, gas flow, pulse and AC parameters included. The benefit for the user is easy handling even of complicated functions, fast set-up for a given task and the assurance of repeatable, high quality welding results, which shortens preparation time and raises efficiency.
- TELWIN reliability and safe operation: The SUPERTIG 302 comes from the well known Italian brand TELWIN, recognised for durable and reliable welding equipment. Solid construction, thermal, overvoltage and undervoltage protections and the option of connecting a liquid cooling unit (for water-cooled torches in intensive work) support a long service life and safe use. The professional gains peace of mind, confidence in equipment that will serve for years and a reduced risk of failures and stoppages at work.
