10 Best Cheap Tig Welders 2025 in the United States

The YESWELDER FLUX-135PRO is a versatile and affordable 3-in-1 welder that combines Flux Core MIG, Stick, and Lift TIG welding processes. It offers a maximum amperage of 135A, suitable for light to medium steel projects up to about a quarter-inch thickness. Its amperage range and adjustable wire feed speed help both beginners and experienced welders find a good welding balance.

While it supports Lift TIG welding, a separate TIG torch is required as it is not included, and it does not feature built-in AC/DC switching, limiting TIG welding mainly to DC. The machine includes a clear digital display for current monitoring, which improves control during use. Weighing just over 11 pounds, it is portable and easy to carry to different job sites. Although a foot pedal control is not included, some users may prefer it for more precise amperage adjustment during TIG welding.

The welder offers safety features such as protection against overheating and voltage spikes, enhancing reliability. It comes ready with flux core wire so welding can begin immediately without shielding gas. This model is well suited for hobbyists or light professionals who need a budget-friendly, multi-purpose welder that emphasizes portability and ease of use. Those requiring advanced TIG features or heavy-duty industrial performance may need more specialized equipment.

The YESWELDER 200A AC/DC Aluminum Tig Welder is a versatile option in the cheap TIG welder category, suitable for hobbyists and small workshop users who require a range of welding capabilities without breaking the bank. Its amperage range and AC/DC capabilities cater well to various materials, including aluminum, making it an excellent choice for those looking to tackle different welding projects. The inclusion of a large LED display enhances usability, allowing for easy monitoring of settings and modes during operation.

One of its standout features is the 6-in-1 functionality, supporting various welding methods like STICK, AC TIG, DC TIG, and spot welding. This flexibility is great for users who need more than just basic welding. The hot start feature further aids beginners by ensuring stable arcs and minimizing spatter, which can be particularly helpful when learning the ropes.

While the YESWELDER offers impressive functions, it does come with some drawbacks. The duty cycle, while acceptable for small jobs, may limit prolonged use in more demanding environments. Portability might also be an issue if you're looking for something extremely lightweight, as this unit caters more towards a stationary setup.

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.
