Welcome to the world of TIG welding! It can definitely be a bit daunting at first with so many options. You’re right about Lincoln and Miller being top choices, but their cost can be prohibitive for beginners. In your case, considering the Best 5 TIG AC/DC Welders For Beginners, I'd recommend looking at models like the AHP AlphaTIG 200X and the Everlast PowerTIG 200DV. These machines offer a great balance of features, ease of use, and affordability. The AlphaTIG 200X is especially user-friendly with its straightforward controls and versatile capabilities, perfect for novices. The PowerTIG 200DV, on the other hand, is known for its reliability and robust build, making it a solid investment as you advance in your skills. Both models can handle AC/DC welding, allowing you to work with a variety of materials, including aluminum and stainless steel. When choosing a welder, ensure it has good reviews on ease of use, durability, and support for both AC and DC operations. Happy welding!
