10 Best Cheap Tig Welders 2025 in the United States

The Lincoln Electric Square Wave 205 TIG Welder is a versatile and portable option suitable for those needing a reliable TIG welder on a budget. One strong point is its ability to weld aluminum well, thanks to adjustable AC Frequency and AC Balance controls that let you fine-tune the bead width and cleaning action. This gives more control over weld quality, especially on different thicknesses and dirty surfaces.

It doubles as a stick welder too, which is great if you want one machine for both precise TIG work and tougher outdoor jobs. The welder runs on either 120V or 230V power, making it flexible for various work environments, and its lightweight design (only 36 pounds) makes it easy to transport. Its multi-process capability and portability make it a solid choice for hobbyists or small-scale welders who don't need heavy industrial power.

This welder is a good pick if you want a compact, adaptable TIG welder that also handles stick welding, without needing to spend a lot.

The ARCCAPTAIN TIG Welder AC/DC 200Amp is a versatile and affordable multi-process welding machine that supports both AC and DC welding, making it suitable for a range of materials including aluminum, magnesium, stainless steel, and carbon steel. It includes advanced waveform options like pulse, square, and triangular waves to reduce heat distortion and improve weld quality, especially on thin metals. With a wide amperage range, it can handle metal thickness from very thin (0.5mm) to moderately thick (up to 10mm), covering most light to medium welding tasks.

The large LED display simplifies setting adjustments, and digital controls allow precise tuning of welding parameters. Weighing about 26.5 pounds, the unit offers decent portability for a TIG welder of this power. It supports foot pedal control, although the pedal is sold separately, which may be inconvenient for users wanting full control immediately. The high-frequency start feature aids easier arc starting. The machine comes with a 5-year service promise and useful accessories like a torch and ground clamp.

Made in China, the welder has received positive user feedback with some noting that its user interface can be complex initially. It is an excellent choice for hobbyists and beginners seeking a flexible machine that covers many welding methods without a high price. However, professionals requiring heavy-duty, continuous use might prefer a welder with a higher duty cycle and a more rugged build.

The Miller 907757 Multimatic 220 AC/DC Multiprocess Welder stands out as a versatile option for those looking to tackle multiple welding processes, including TIG, MIG, and flux-cored welding. With its ability to automatically adjust settings based on your last used process, it makes the welding experience much more user-friendly, especially for beginners. The Auto-Set Elite and Pro-Set features help in achieving consistent and high-quality welds, reducing the hassle of manual adjustments, which is a significant advantage for users who want efficiency and precision. Additionally, this welder is portable, weighing in at 56 pounds, and can operate on both 120V and 240V power sources, making it suitable for various job sites. The inclusion of essential accessories like a MIG gun, TIG torch, and foot control also adds value, allowing users to start working right away.

However, while the welder is portable, its total weight of 94 pounds might be cumbersome for some users during transport. Being a multi-process welder, it may not deliver the same high performance as dedicated TIG welders for very specific applications. Users looking primarily for high-end TIG welding might find it lacking in certain advanced features.

The Miller Multimatic 220 AC/DC offers a great balance of features for hobbyists and light professional use, particularly for those who want the flexibility to switch between different welding processes. Serious welders focused solely on TIG applications may want to consider dedicated options for optimal performance.
