10 Best Cheap Tig Welders 2025 in the United States

The ARCCAPTAIN 250A welder is a versatile 6-in-1 machine combining MIG (both gas and gasless), Lift TIG, Stick, Spot, and Spool Gun welding, making it attractive for users who want multiple welding processes in one unit. It offers a solid amperage range up to 250A, suitable for welding a variety of metals including mild steel, stainless steel, and aluminum. The digital controls and synergic MIG mode help beginners get started quickly, while manual adjustments allow more experienced users to fine-tune settings. The machine runs on both 110V and 220V power, providing flexibility for different workshop setups.

For TIG welding, an extra purchase of the Lift TIG torch is required. The welder lacks AC capability, which is important for welding aluminum with TIG, limiting its TIG performance compared to dedicated TIG welders that support AC/DC. The machine weighs 20.5 pounds and has a compact size, making it fairly easy to move around. It does not include built-in foot pedal control or high-frequency start, features valuable for precise TIG welding control and arc starting without touching the tungsten.

Safety features and a large LED display enhance user-friendliness. This welder is a solid choice if you want an affordable, multi-process machine with decent power and beginner-friendly controls, but it may not meet the needs of users focused primarily on professional TIG welding, especially aluminum work requiring AC and high-frequency start.

The ESAB Rebel EMP 205ic is a versatile and portable multi-process welder that handles MIG, Stick, and both AC/DC TIG welding, making it a strong choice for users needing flexibility in one machine. It offers professional TIG features such as high-frequency start on both AC and DC modes, allowing for easier arc initiation and cleaner welds, which is a plus for TIG welding tasks.

With a relatively lightweight design (around 49-59 pounds) and a sturdy roll cage, it’s easy to move around job sites or workshops. The sMIG technology is a smart feature that adapts to your welding style, helping beginners achieve more consistent results while boosting productivity for experienced welders. The welder includes a clear multilingual display and memory settings, which simplify adjustments and fine-tuning, supporting both new and skilled operators.

This welder suits those looking for an all-in-one, professional-grade machine that’s both portable and capable across welding types but might be more than what purely budget-focused TIG welders need.

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.
