The CastoTig 2202 AC/DC is a true specialist in the TIG method. TIG AC mode offers full control over welding aluminum and magnesium: you can precisely adjust the AC balance (affecting cleaning and penetration), AC frequency (up to 250Hz for a focused arc), and select the current waveform (rectangular, sinusoidal, triangular) to optimize the process for different thicknesses and alloys. In DC TIG mode, you’ll get excellent results on stainless steel, carbon steel, copper or titanium. The advanced Pulse function (AC and DC), with adjustable frequency (up to 200Hz), base/peak current and fill, allows you to weld thin materials with minimal distortion and create aesthetic welds. Arc striking is assured with HF (non-contact) and Lift-Arc options.

In addition to its advanced TIG capabilities, the CastoTig 2202 AC/DC is also a very capable MMA welder, offering welding current up to 180 Amper. You can easily handle most common types of electrodes: rutile, alkaline, stainless steel. The welding process is supported by key features: adjustable Hot Start (0-100%) for easier arc ignition, adjustable Arc Force (0-100%) for arc stabilization and prevention of electrode sticking, and Anti-Stick. Interestingly, MMA works on both DC and AC current (although less common), adding to the versatility. It’s an ideal addition for assembly, repair and construction work.

The CastoTig 2202 AC/DC uses advanced digital control, which translates into precision and repeatability of parameters. The control panel, despite its wealth of features, is designed with ease of use in mind. A digital display shows key parameters, and adjustments are made via dials and buttons (some versions with easy-to-read icons). The unit offers memory for welding programs (e.g., 9 channels or more), which is invaluable for repetitive tasks – save the perfect settings once and recall them in a second! The VRD (Voltage Reduction Device) function reduces idle voltage, increasing operator safety. It combines sophistication with a user-friendly interface.

Designed with professionals in mind, the CastoTig 2202 AC/DC welder combines a robust industrial design (IP23S) with surprising mobility (weighing only about 12-15 kg!). You can easily take it to any work site. The high power factor (cos φ 0.99) suggests the use of PFC technology, which means high energy efficiency, less strain on the grid and the ability to operate on standard 230V protection. The wide tolerance of the supply voltage allows stable operation even when powered by a generator or on long extension cords. It is the ideal tool for field service work and dynamic workshop environments.

The CastoTig 2202 AC/DC is the heart of a complete welding system. It is fully compatible with a wide range of professional TIG holders (gas-cooled like the SR26, or liquid-cooled like the SR18 when a cooler is connected) and MMA holders. An optional liquid cooler (e.g., Castolin CoolTig 22) is available for increased performance in heavy welding, especially TIG AC aluminum. The mobility of the kit can be increased with dedicated transport carts. Precise control of current during welding will be provided by foot pedals or remote hand controls. By choosing this used unit, you gain access to a platform that can be expanded with original Castolin accessories, adapting it perfectly to your needs.

This is a unique opportunity! We offer a used Castolin CastoTig 2202 AC/DC welder in what can only be described as “like new” condition. The equipment has been carefully inspected by us and is fully ready for professional use, offering its full advanced TIG and MMA capabilities. This is a chance to acquire a premium piece of equipment from the renowned Castolin Eutectic, a company known for providing solutions for the industry, at a much more affordable price than a new unit. Ideal for those who want to benefit from the best technology without straining their budget. We guarantee excellent technical and visual condition! Remember that Castolin is a well-established brand, which makes the availability of supplies easier. (You can add information here about a possible start-up warranty or short-term vendor warranty.)
