10 Best 120 Volt Mig Welder 2025 in the United States

The YESWELDER 135Amp MIG Welder is a versatile machine designed for both beginners and experienced users. With an amperage range of up to 135 amps, it can effectively weld mild steel up to 2/5” thick, making it suitable for a variety of welding projects. Its 3-in-1 capability allows for MIG, Stick, and Lift TIG welding, although you'll need to purchase an additional Lift TIG torch for that function. This flexibility is a strong point, particularly for users who want to tackle different types of welding tasks without investing in multiple machines.

The digital display is a standout feature, enhancing user experience by making settings easier to read and adjust. The synergic control means that when you change the wire feed speed, the voltage automatically adjusts, which simplifies the welding process for those who may just be starting out. Safety features such as automatic compensation for voltage fluctuations and overload protection are reassuring, especially for novice welders.

Portability is another advantage, as the welder weighs only 11.4 pounds, making it easy to transport to job sites or different locations. However, while its lightweight design is beneficial, some users may find the build quality less robust than heavier models. It’s worth noting that the unit does require a bit of setup and understanding before use, particularly if you plan to operate at higher amperages.

The Lincoln Electric 90i MIG and Flux Core Wire Feed Welder is a solid choice for those seeking a portable and user-friendly welding machine. This welder operates on 120V power, making it convenient for use in various settings. Its lightweight design (weighing only 15 lbs) combined with a shoulder strap enhances portability, making it a great option for maintenance tasks or on-the-go welders.

One of its standout features is the ease of operation, provided through simple controls for wire speed and voltage. This makes it approachable for beginners, while professionals will appreciate its efficiency and smooth welding capabilities thanks to the inverter power source. The welder is suitable for small projects, such as DIY tasks, hobby welds, and home repairs, and it can handle up to 1/4” thickness with flux-cored wire and 3/16” with solid MIG wire.

There are a few drawbacks to consider. The amperage range and duty cycle are somewhat limited compared to larger, more industrial machines, which could restrict its usefulness for more demanding jobs. Additionally, while it includes essential accessories, users looking for advanced features or greater flexibility in welding processes may find this welder lacking.

The bestarc 145A MIG Welder is a versatile welding machine that stands out for its 3-in-1 functionality, allowing it to operate as a MIG, TIG, and Stick welder. This makes it a great choice for users who need a multi-purpose tool. Its 145-amp maximum current is suitable for a range of welding tasks, including working with stainless steel and carbon steel.

The dual voltage capability (110V/220V) adds to its flexibility, making it usable in various power environments. Additionally, the welder is quite portable, weighing in at just 13.7 pounds, and includes a shoulder strap for easy carrying. This portability is ideal for users who need to move their equipment frequently or work outdoors. The digital screen display is a convenient feature that allows you to see and adjust voltage and current settings without removing your helmet, enhancing both safety and efficiency.

The synergic control with IGBT technology helps in automatically matching the recommended voltage and wire feed speed, which is beneficial for beginners and saves time for professionals. While the welder's build quality is generally good, it is manufactured in China, which may raise concerns for some users regarding long-term durability. The bestarc 145A MIG Welder offers a good mix of features, including portability, ease of use, and multi-functionality, making it a solid option for both beginners and seasoned welders.
