Perfect Aluminium Welding: Advanced TIG AC Process Control
Welding aluminium and its alloys calls not only for power but above all for precision and control of the AC arc parameters. The TELWIN SUPERIOR TIG 422 AC/DC rises to the task and offers advanced adjustment of the alternating current frequency (AC Frequency) in the range 20-200 Hz. A higher frequency gives a more concentrated and stable arc, which translates into a narrower heat affected zone, deeper penetration and greater welding speed. This is the key when joining thinner parts and wherever maximum precision is required.
In addition the welder allows precise control of the AC wave balance (AC Balance) in the range 20-60%. The balance setting decides the proportion between the duration of the positive half wave (responsible for cleaning and removing oxides from the aluminium surface) and the negative half wave (which secures penetration and fusion). The right balance setting is the key to a clean, smooth weld with no porosity or inclusions, while securing the right depth of fusion and keeping tungsten electrode wear low. Thanks to these functions even complex welding jobs on aluminium become easier to carry out, and the results are repeatable and in line with the highest quality standards.
Precision and Heat Control: Intelligent TIG Pulse Modes
The TELWIN SUPERIOR TIG 422 AC/DC takes pulsed welding to a new level of sophistication. The TIG PULSE function (for DC as well as AC) allows precise modulation of the welding current between a peak value and a base value. This is invaluable when welding thin material (it keeps the risk of burn through and distortion low), material sensitive to overheating (such as duplex stainless steels or nickel alloys) and when welding in constrained positions, where control of the weld pool is critical.
The machine offers various pulse modes, among them EASY PULSE, which chooses the best pulse parameters automatically on the basis of the welding current that was set, simplifying setup considerably and letting even less experienced welders reach excellent results. Advanced users have full adjustment of the pulse frequency, the duty ratio and the base and peak current values. The benefits of advanced pulsing include better control of the heat input, narrower and better looking welds, a reduced heat affected zone, deeper penetration with a lower heat input and the ability to weld material of different thickness. SYN PULSE (Synergic Pulse) makes work easier still by adjusting the pulse parameters automatically to the peak current that was set, which guarantees the best welding conditions.
Output and Ergonomics for Professionals: Construction and Working Functions
The TELWIN SUPERIOR TIG 422 AC/DC was designed for daily, intensive work in an industrial environment. The high duty cycle (400A @ 40% for TIG, 350A @ 35% for MMA) guarantees the ability to weld for a long time at high currents with no risk of overheating the machine. The marking "+ACC." in the model name often indicates that the set includes a professional liquid cooling unit for the TIG torch, which is necessary when welding at high currents and secures working comfort and a longer service life for the torch consumables.
The machine also offers full value MMA welding with stick electrodes (rutile, basic, cellulosic, stainless steel, cast iron) up to 6 mm in diameter. Functions such as Arc Force (dynamic short circuit current control), Hot Start (easier electrode striking) and Anti-Stick (prevention of electrode sticking) make work considerably easier and improve MMA weld quality. The intuitive digital control panel with a clear display and the option of storing 9 individual welding programs (JOBs) allows the best settings for repeated jobs to be recalled quickly, which translates into time saved and a guarantee of repeatable results. A solid metal housing and a high IP23 protection rating secure resistance to hard workshop conditions.

Key Features and Benefits
- Versatile TIG AC/DC Welding with Full Arc Control: The machine offers advanced TIG welding with alternating current (AC) with precise adjustment of the frequency (20-200 Hz) and of the wave balance (20-60%), which is the key to excellent weld quality and effective oxide cleaning when welding aluminium, magnesium and their alloys. DC mode secures a stable arc for welding stainless and carbon steel, copper, titanium and other metals. For a professional this means the ability to work with many materials using a single machine, a guarantee of deep penetration, good looking welds and a low risk of defects such as lack of fusion or porosity, which saves time and material.
- Strong Industrial Power and a High Duty Cycle: With a maximum TIG welding current of 400A (at a 40% duty cycle) and 320A (at a 60% duty cycle), the SUPERIOR TIG 422 is ready to weld thick sections and to work in demanding industrial conditions. The ability to work continuously at high parameters shortens project times and raises productivity. For the welder this means reliability, the ability to weld material even more than ten millimetres thick and the certainty that the machine will meet the heaviest jobs without overheating.
- Advanced TIG Pulse Functions (EASY PULSE, SYN PULSE): The welder is equipped with extensive pulsed welding modes, among them the innovative EASY PULSE, which optimises the pulse parameters automatically, and SYN PULSE, which secures synergic control. Pulsing allows precise control of the amount of heat introduced, which is invaluable when welding thin material, stainless steel and nickel alloys. The benefits are less distortion of the material, better control of the weld pool, the ability to obtain narrower and better looking welds and excellent fusion, especially in constrained positions.
- Flexible Three Phase 230V/400V Supply: The ability to connect the machine to a 3x230V as well as a 3x400V mains secures unusual flexibility and universal use. Thanks to this the welder can be used in varied workshop and industrial conditions, with no need for additional transformers. For the user this means greater mobility, easy adaptation to the existing power infrastructure and the ability to work in different locations.
- Intelligent Supporting Technologies (THINSPOT, VRD, Program Memory): The THINSPOT function allows fast and precise spot welding with a minimal heat effect, ideal for thin sheet. The VRD system (Voltage Reduction Device) lowers the open circuit voltage and raises operator safety, above all in a humid environment. The option of storing up to 9 personalised welding programs (JOBs) speeds up work on repeated jobs considerably and guarantees consistent parameters. That translates directly into higher efficiency, safety and repeatable weld quality.
