Arc ignition in the TIG method is a key moment that determines the quality of the entire weld. The Telwin TECNICA TIG 190 DC welder uses an advanced LIFT ARC system. Unlike HF (high frequency) ignition, the LIFT method involves gently touching the tungsten electrode to the material to be welded and lifting it slightly. A special electronic circuit detects the contact and initiates a low current flow, which prevents the electrode from sticking and damaging it.

This solution eliminates the risk of tungsten particle contamination of the weld pool, which is critical when welding materials that require the highest purity, such as stainless steels, titanium or nickel alloys. In addition, the absence of an HF ionizer means less electromagnetic interference, which is important in environments with sensitive electronic equipment. For the welder, this guarantees precise starts, clean welds and the ability to work in diverse conditions without worrying about interference.

The Telwin TECNICA TIG 190 DC LIFT is not only a precision TIG, but also a powerful MMA welding tool. To meet the expectations of professionals, the device is equipped with three key functions to optimize the process of welding with covered electrodes. Hot Start provides easier arc ignition by delivering a higher current pulse when the electrode contacts the material. This is especially helpful when starting to weld cold materials or when using electrodes with difficult ignition.

Arc Force (arc dynamics) is a function that automatically adjusts the welding current according to the arc length. When the arc is shortened (e.g., when the electrode is brought closer to the material), the current is temporarily increased, which prevents the arc from dimming and the electrode from sticking, and ensures a deeper fusion. On the other hand, when the arc is too long, the current is stabilized. Anti-Stick is an anti-short-circuit system that, if the electrode sticks to the material, immediately reduces the welding current to a minimum, allowing the electrode to be easily detached without damage or overheating. These technologies synergistically affect welding fluidity, weld quality and welder comfort, even in difficult positions.

One of the biggest advantages of the Telwin TECNICA TIG 190 DC LIFT welder is its exceptional mobility combined with robustness. Thanks to the latest generation of inverter technology, the device is characterized by small dimensions and low weight (the welder itself is about 5.5 kg), which makes it extremely handy. The version with the designation ACC.+C.CAS is supplied in a practical and durable aluminum case, which not only facilitates transportation, but also protects the device and accessories from mechanical damage and the influence of external conditions.

The welder is designed to work in a variety of conditions. It is IP23-rated, which means protection against splashing water at an angle of up to 60° from the vertical and against solid objects with a diameter of more than 12.5 mm. What’s more, it is designed to be powered by a generator (with a minimum power of 6 kW), which gives full independence from the electric grid. Built-in thermal, over-voltage, under-voltage and over-current protection further enhance its reliability. For the professional, this means the ability to take on jobs anywhere, the certainty of the equipment’s operation and the security of the investment.
