10 Best Cheap Tig Welders 2025 in the United States

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 PRIMEWELD TIG225X is a solid choice for those looking for an affordable TIG welder that can handle a variety of materials such as aluminum and stainless steel. With a maximum output of 225 amps, it offers ample power for both thin and thicker metals. The ability to switch between AC and DC welding makes it versatile, especially for users needing to work on different types of materials. The pulse function is a great feature for precision welding, particularly on aluminum, as it helps control heat input and reduce warping.

Portability-wise, the welder weighs 90 pounds, which is somewhat heavy compared to smaller models, but it’s still manageable if you plan to use it in a fixed location or a shop. The inclusion of a high-frequency (HF) start allows for easier arc initiation, which is a notable strength for beginners and experienced welders alike. Additionally, the foot pedal control is a significant advantage, giving users fine-tuned control over the welding process, enhancing precision and ease of use.

There are a few drawbacks worth noting. Some users might find it lacking in duty cycle performance, particularly during extended use, which could limit its effectiveness for heavier projects. Also, while the CK17 Flex Torch is a good quality torch, some beginner welders may require a bit of practice to master the technique effectively, especially when adjusting to the flexibility of the torch head.

The PRIMEWELD TIG225X is an excellent choice for DIY enthusiasts and professionals who need a reliable, affordable welder with good features. It's best suited for users who require versatility in their welding tasks but may not be ideal for those needing ultra-portable solutions or high-duty cycle performance for prolonged commercial use.

The Bestarc MIG145 Welding Machine offers a versatile 3-in-1 functionality, supporting Gas/Gasless MIG, Lift TIG, and Stick welding, which makes it suitable for various welding tasks on stainless steel, carbon steel, and thicker steel. However, the maximum current is limited to 145 amps, which might not be sufficient for heavy-duty welding jobs.

The digital screen display of voltage and current parameters is a handy feature that enhances efficiency and accuracy, especially as you can make real-time adjustments without removing your helmet. This welder employs synergic control, which automatically matches the recommended voltage and wire feed speed, making it user-friendly for both beginners and professionals. The dual-voltage capability (110V/220V) adds to its flexibility, allowing it to work in different power environments seamlessly.

Weighing just 13.7 pounds and featuring a shoulder strap, this welder is highly portable, ideal for outdoor use. However, it lacks certain TIG-specific features like foot pedal control and high-frequency start, which might limit its appeal for precise TIG welding tasks. Despite these limitations, it is an efficient and versatile option for those seeking a budget-friendly multi-function welding machine.
