TELWIN TECHNOLOGY TIG 222 AC/DC: Master-Level Precision and Welding Versatility for Professionals
Meet the TELWIN TECHNOLOGY TIG 222 AC/DC, an inverter welder built for work that pushes the limits of the craft. This is not just another tool, it is a partner on demanding projects, from precise welds on aluminium to heavy structures in stainless and carbon steel. You keep full control over every aspect of the arc, whatever the material and the welding position.
Where quality and reliability decide the result, the TECHNOLOGY TIG 222 AC/DC stands out with advanced microprocessor technology that delivers both accurate welding parameters and straightforward operation. You do not have to compromise. TIG welding with alternating current (AC) opens the way to clean joints on aluminium and its alloys, with tidy, strong and good looking welds. The DC mode in turn lets you work precisely with stainless and carbon steels, copper and titanium.
This welder comes from years of work by Telwin engineers and their interest in tools that genuinely make the job easier. Integrated functions such as pulsed TIG welding (TIG PULSE), which limits distortion and improves control over the weld pool, and advanced AC settings (balance, frequency) put the process in your hands. On top of that the machine welds well in MMA, which makes it a truly universal choice for a workshop or a production plant.
Designed for hard conditions and heavy use, the TELWIN TECHNOLOGY TIG 222 AC/DC stands for Italian build quality and reliability. Its compact body and fairly low weight make it easy to carry and to use on site, without giving up power or output. The accessories supplied let you start work almost straight out of the box. Invest in technology that takes the quality of your work to a new, master level.
Advanced Capabilities of the TELWIN TECHNOLOGY TIG 222 AC/DC 230V + ACC.
Clean Welds on Aluminium with Advanced TIG AC
TIG AC welding of aluminium calls for precise control of the arc parameters, and the TELWIN TECHNOLOGY TIG 222 AC/DC gives you the tools for it. The key function is AC balance adjustment, which lets you set the trade-off between penetration and the cleaning of oxides from the aluminium surface. A larger share of the negative half wave (more cleaning) suits heavily contaminated surfaces, while a larger share of the positive half wave (more penetration) gives deeper fusion.
A higher frequency stabilises the arc, which helps above all on thin aluminium sheet. These settings give professionals full control over the process and make it possible to produce welds of good quality, strength and appearance even on difficult aluminium alloys.
Intelligent TIG Pulse for High Precision and Control
TIG Pulse welding in the TECHNOLOGY TIG 222 AC/DC changes how you join thin materials that are sensitive to overheating, such as stainless steel or nickel alloys. With full adjustment of the pulse parameters, peak current (Ip), base current (Ib), pulse frequency (Hz) and pulse duty cycle (%), the welder can meter heat into the weld pool exactly as needed.
The peak current provides the fusion, while the base current allows controlled cooling and solidification of the weld. The result is a clear reduction in material distortion, better control over root penetration, above all in constrained positions, and the option of neat, evenly stacked beads. Telwin also often implements the "EASY PULSE" function, which sets the pulse parameters automatically and helps less experienced welders while keeping quality high. This suits the food, chemical and aerospace industries and any job where the highest precision is required.
Reliability and Power in MMA Mode for Varied Jobs
The TELWIN TECHNOLOGY TIG 222 AC/DC is not only a strong TIG machine, it is also an efficient and reliable unit for MMA welding with covered electrodes. With output up to 180A it handles rutile and basic electrodes as well as electrodes for stainless steel and cast iron, in diameters up to 4.0 mm. That versatility is what professionals working in varied conditions and with varied materials value.
The machine has the key functions that support MMA welding: Arc Force (dynamic short circuit current control) prevents the arc from dying and keeps it stable even with difficult electrodes or a short arc. Hot Start raises the current at the beginning of the weld and makes striking the electrode easier, above all on damp or cold material. The Anti-Stick function automatically reduces the current when the electrode sticks to the workpiece, which protects it from overheating and makes it easier to free. These systems make MMA welding simpler and more efficient, and the joints come out better.
Mobility and Durability: a Partner at Every Work Site
Professional welders often work in varied settings, from a fixed workshop to building sites and assembly work in the field. The TELWIN TECHNOLOGY TIG 222 AC/DC was designed for maximum mobility with no compromise on performance. Its compact dimensions (430x170x340 mm) and fairly low weight (12.5 kg) make it easy to transport and to manoeuvre even in tight spaces.
A solid housing with IP23 protection keeps out dust and moisture, which matters when conditions get rough. The machine also runs from power generators of suitable output and voltage stability, which adds to what you can do with it. Inverter technology not only cuts weight and size, it also gives high energy efficiency and therefore lower running costs. Wherever the next job takes you, the TECHNOLOGY TIG 222 AC/DC is ready to work.

Key Features and Benefits
- AC/DC TIG and MMA welding versatility: The welder covers TIG welding with alternating current (AC), suited to aluminium and its alloys and to magnesium, and with direct current (DC) for stainless and carbon steels, copper, nickel, titanium and their alloys. On top of that, an advanced MMA mode with adjustable Arc Force and Hot Start plus Anti-Stick makes it a very universal tool. For a professional that means one machine for many tasks, lower spending on equipment and more flexibility day to day.
- Advanced TIG arc control with the PULSE function: Precise control of the TIG arc parameters, including pulsed welding (TIG PULSE and EASY PULSE), gives good command of heat input, limits thermal distortion and improves bead formation, above all on thin material. Adjustable pulse frequency, base current and peak current are the key to welds of high quality and appearance even in difficult positions. The result is better fusion, a smaller heat affected zone and a clean weld face.
- High output and "Made in Italy" reliability: A solid duty cycle (220A @ 30% in TIG) together with Telwin build quality keeps the machine dependable even under heavy use. It was designed for professional work where continuity matters and downtime costs money. The professional gets a machine that keeps up with long projects, holds its parameters steady and lasts.
- Smart functions that make welding easier: The machine has a set of functions that support the welding process, such as HF (non-contact) and LIFT (contact) arc striking for TIG, which keeps tungsten out of the weld. In MMA mode, Hot Start (easier electrode striking), Arc Force (arc stability and protection against sticking) and Anti-Stick (protection against the electrode sticking) make work noticeably easier and improve joint quality. That is real support for the welder and leaves room to focus on accuracy.
- TIG spot welding: A dedicated TIG spot welding function joins thin sheet quickly and accurately with minimal distortion. It suits assembly and preparation work and improves both productivity and the look of tack joints. For a professional that means time and material saved with quality kept up.
