10 Best Wire Welders 2025 in the United States

The Lincoln Electric 90i FC Flux Core Wire Feed Welder is an excellent choice for anyone looking to tackle small welding jobs, whether at home or on a construction site. Its lightweight design (just 15 lbs) and shoulder strap make it highly portable, ideal for maintenance work or mobile applications. With a 120V power source, you can easily plug it in anywhere, and it effectively welds materials up to 1/4" thick, making it suitable for various DIY projects and light repairs.

One of the standout features is its user-friendly operation. The welder includes simple controls for adjusting the wire feed speed and voltage, allowing beginners to get comfortable with the machine quickly. The included accessories, such as the welding gun and protective metal case, add value and convenience, ensuring you're ready to start welding right out of the box.

However, there are a few limitations to consider. While its portability is a significant advantage, the 90i is best suited for lighter tasks and may not perform as well for heavier industrial or professional welding jobs. The duty cycle may also restrict longer welding sessions due to potential overheating, so it's important to be mindful of that during use. Additionally, the welder primarily operates on flux core welding, which may not be suitable for all types of welding projects.

The Lincoln Electric 90i FC is a solid option for hobbyists and DIY enthusiasts seeking an easy-to-use, portable wire welder for small jobs. Although it may not cater to more intensive welding needs, its combination of simplicity and effectiveness makes it a great introduction to welding for newcomers.

This eliminates the guesswork and makes the welding process smoother and more efficient.

The welder also boasts a segmented display, which enhances precision by enabling clear and accurate adjustments in both Manual and Auto-Set modes. Its 120V input power makes it highly versatile, as it can be used with standard household power outlets, eliminating the need for special electrical setups.
