5. Forney Easy Weld 261 Welder

Input Power: 120V

Duty Cycle: 30%

Weight: 19 lbs.

Amperage: 30-140 Amps

Power Settings: Infinite voltage, 10-position wire feed speed control; handles 2 to 10 pounds wire spools


Forney never quits the race to produce the best MIG welder for Aluminum. It produces machines with great versatility and tons of useful features.

One such example is Forney 261 Easy Weld. To begin with, it is one of the few flux-core welders available in the market. While most of the flux-core welders have a small amperage range and limited controls, Forney easy weld 261 Is quite the opposite.

It is easier than TIG, stick, and MIG welders to operate as the front-panel design is quite beginner-friendly welder. Moreover, the machine offers infinite wire feed speed and voltage controls. Most of the welders prefer infinite settings rather than tapped controls. This does not only give you the freedom to tune up settings but also helps you to achieve maximum welding performance.

Another noticeable feature of the welder is its weight. At 19 pounds, it weighs nothing as compared to other welders. As you are not doing gas-shielded welding, you do not have to invest in gas cylinders as well. For hobbyists not looking to spend money on gas cylinders, it is the perfect welder for aluminum and steel.

However, there’s one thing that differs from other flux-core welders- the plastic drive roll system. While most of the manufacturers build it with cast aluminum, Forney goes with plastic. But it is not a huge disadvantage.

It is one of the very few MIG aluminum welders to have inverter technology. From a price point of view, other welders comparable to this welder are using transformer technology. However, Forney’s cheap aluminum welder is an exception in the welder industry.

Pro Tip

To make multiple weld-passes with the welder for aluminum and steel, clean the slag off before you move on to the next welding pass.

Is Aluminum Welding Any Difficult Than Steel Welding?

If it’s your first time working with aluminum, note that aluminum welding is a little different than traditional steel welding. Only a few MIG welding machines can produce quality aluminum welds that last.

I always choose a heavy-duty welder that can weld both steel and aluminum.

The question arises, “Is welding aluminum difficult than welding steel?”.

Well, the answer to this question lies somewhere in between. Don’t expect to produce the ideal results in the first go. However, with a little practice, you’ll get used to it.

A Definitive Guide to Successfully Weld Aluminum

How To Weld Aluminum Guide.

Above anything else, aluminum is a softer metal in its pure form and has various applications. It is often used with different alloys to increase strength that makes it a better choice than steel.

Moreover, you’ll need a spool gun to weld aluminum. All the welders reviewed on this list for best MIG welders for aluminum either come with a spool gun or can attach one.

Aluminum reacts to the heat and input power differently as compared to steel. Thus, you can’t weld it with all MIG welders.

However, with the right technique, procedures, and equipment, you’ll get around aluminum welding just fine.

Following are my personal aluminum welding tips you must consider when MIG welding your first aluminum project.

Keep the surface clean

When welding aluminum, make sure to keep the base material clean. It is recommended to use a steel brush to remove the oxide layer, extra particles, or any debris.

Make sure the steel brush you have is clean and is only used for the aluminum welding process.

Material Thickness

You can weld a minimum of 14 gauge (0.074 inches) thick aluminum sheets and heavier. To weld aluminum sheets less than 14 gauge, you might want to consider a heavy-duty MIG welder or preferably TIG equipment.

The Best Gas to Use

Make sure to use 100% argon shielding gas as aluminum is a non-ferrous metal. It is recommended to use a flow rate of 20-30 cubic feet.

What Filler Metal You Should Use?   

The alloy filler metal you use with aluminum determines the strength of your welds. The 2 most commonly used filler wires I use are ER5356 and ER4043. These are easily available on the market.

You can also look for some other filler wires that fit your aluminum welding project or application.

Frequently Asked Questons – FAQs


Overall, Hobart 210 MVP is certainly the best aluminum MIG welder on this list. After that, Lotos MIG175 is also a budget-friendly choice.

In the end, all it comes down to your features preference and usage. A welder that works well for me may not serve the same deal to your kind of work. Getting me?
