10 Best Mig Welder For Aluminum 2025 in the United States

The ARCCAPTAIN MIG Welder is a versatile 6-in-1 machine that covers multiple welding styles including gas and gasless MIG, stick, lift TIG, and spot welding. With a maximum amperage of 200A, it offers enough power for light to medium aluminum projects. The digital control with synergic settings simplifies adjusting wire feed speed and current, making it easier for beginners to get good welds without much fiddling. It supports various wire sizes including aluminum-specific wires, but some rollers for certain wire diameters need to be purchased separately, which adds a small extra cost.

This welder includes a spool gun connector option, which is essential for aluminum MIG welding to reduce burn-through and improve control. However, the spool gun itself is not included, so you’ll need to buy that separately if you want to weld aluminum effectively. The machine uses shielding gas, which is standard for clean aluminum welds, and offers protective features to prevent overheating and electrical issues, adding safety for the user.

Portability is decent for its class, weighing 28 pounds and featuring both a handle and a shoulder strap, making it suitable for outdoor or farm use as well as home DIY projects. The bright LED display clearly shows settings without removing your helmet, which is a thoughtful touch. While advanced TIG welding requires a separate TIG gun, the ARCCAPTAIN welder’s flexibility, ease of use, and good safety features make it a strong choice for hobbyists and light professionals looking to weld aluminum and various metals with one machine.

The YESWELDER 135Amp MIG Welder is a versatile option for those interested in aluminum welding. It supports three welding processes: MIG, Stick, and Lift TIG, which makes it suitable for various projects. The 135 Amp output allows for welding mild steel plates up to 2/5", making it a solid choice for both beginners and experienced welders. The advanced digital display enhances user experience by providing clear visibility, and the synergic control feature automatically adjusts voltage when the wire feed speed is changed, simplifying the process for newcomers.

Portability is another strong point; weighing only 11.4 lbs, it’s easy to transport, perfect for on-site jobs. Additionally, safety features such as automatic voltage compensation and overload protection are reassuring for users.

There are a few drawbacks to consider. While it’s effective for MIG and Stick welding, users interested in Lift TIG will need to purchase an additional torch, which could add to the overall cost. Some limitations exist when welding thicker aluminum materials, so while it meets the basic needs, it might not be ideal for heavy-duty applications. Furthermore, the welder's performance at higher amperage levels requires specific settings for optimal results.

The Lincoln Electric 90i MIG and Flux Core Wire Feed Welder is a versatile welding machine usable with 120V input power, making it convenient for plugging in just about anywhere. It's designed to handle both flux-cored welding wire (up to 1/4” max thickness) and solid MIG wire (up to 3/16” max thickness). This welder is particularly suited for small weld jobs and DIY projects, making it ideal for hobbyists, home repairs, or maintenance work.

Its light weight (15 lbs) and compact size, coupled with a shoulder strap, offer excellent portability which is great for mobile welders or those needing to transport their equipment frequently. Additionally, the metal case adds durability and protection, enhancing its suitability for outdoor or harsher environments.

The machine is user-friendly with simple two-knob controls for wire speed and voltage, making it accessible for beginners, while the inverter power source provides more efficient operation and smoother weld characteristics. The Lincoln Electric 90i is a solid choice for small-scale welding jobs offering portability and ease of use, but may not meet the needs of more heavy-duty or specialized welding tasks.
