I couldn’t believe my eyes when I read……..
Aluminum is the world’s most abundant metal, comprising about 8.2% of the Earth’s crust.
And every year, the use of aluminum is increasing due to its recyclability and many other useful characteristics. It is a widely used material in different industries such as construction, transportation, electrical, consumer goods, and many more.
In continuation of this, the necessity of welding machines for cutting aluminum is on an increasing trend.
but there is a problem:
Virtually, you can’t cut aluminum with any welding machine. Even if you use a regular welding machine to cut aluminum, you will end up with a sheet of burnt aluminum due to its low melting point.
What does this mean to you?
This means a specialized aluminum welder is necessary to handle the aluminum cutting project.
So, what are the best welders for aluminum?
We consulted with welding experts who work with aluminum dedicatedly and shared a list of aluminum welders with them. They used those machines and told us that the below 7 models are good enough.
Feeling curious to know our thought?
Let’s dive right in.

What kind of welder is used for aluminum?
You can follow below welding processes to weld aluminum.
- Laser and Electron Beam Welding
- Resistance Welding
Let’s learn a bit more about these mentioned processes.
1. Gas tungsten arc welding (TIG)
The other name of the TIG welding process is GTAW; the full form is aluminum gas tungsten arc welding. It is a popular welding process for aluminum because findability issues can easily be avoided since mechanical wire feeding is not required in this process. You will get extremely clean results with this process.
2. Gas metal arc welding (MIG)
This is another widely used aluminum welding process is known as GMAW (gas metal arc welding). It uses mechanical arc feeding, which can lead you to feedablity issue, but the good news is, using a spooled wire, preventing this issue is possible. And guess what? Compared to GTAW, deposition rates are higher, and travel speed is faster.
3. Laser and electron beam welding
Often, you can use the beam welding process. Should you preheat aluminum before welding?
Material light reflectivity is one of the biggest concerns when dealing with laser beam welding. Simultaneously, problems are less with electron beam welding because vacuum condition is used, and light is not the energy medium in this process.
4. Resistant welding
It is a good option for aluminum welding. Some challenges are also there with this process. Special resistance tips and equipment are necessary, and adjusting the parameter development time is significant to overcome this process’s issues.

How many amps do you need to weld aluminum?
You will need to follow a formula to get the answer to the question of how many amps do you need to weld aluminum.
For a metal of 0.001”, 1 AMP is necessary to weld aluminum when other variables remain constant.
For instance, welding a 1/8” aluminum will require 125 AMP, and remember variables related to aluminum will stay constant at this point.
How can I weld aluminum cheap? Well, when choosing a welder for aluminum, proper selection of the welder is significantly essential. It would help if you didn’t select a welder without knowing your project requirement and the welder’s amperage capacity.
What to Look in a Good Aluminum Welding Machine?
1. Output Power
The final result of aluminum welding depends a lot on the amperage of an aluminum welder. When you have thicker materials in your hand to weld, choose a high amperage machine. For thin material, it would be best to choose a less amperage machine.
TIG welding generates less heat than MIG welding. 5/10 AMP – 250 AMP is a good range for welding aluminum. You can weld 60 mm thick aluminum using these welders.
AC is required to weld aluminum. However, if you bought an aluminum welder that runs with AC.
However, you will find MIG and TIG welders able to run with AC or DC or both. When welding aluminum, the oxidation layer creates a problem, and alternating current helps to cope with it.
3. Controlling the Heat
By now, you already know that MIG welders create more heat. Look for an aluminum welder with a pulse welding feature that allows you to control the heat.
The machine adjusts automatically from full load current to low load current when the pulse welding feature is activated. The torch helps to maintain the pressure as it cools the head.
4. Duty Cycle
Many beginners don’t know what the duty cycle is.
The duty cycle tells you the frequency of welding in 10 minutes’ interval. It is one of the crucial factors of MIG welders. This feature varies from model to model.
5. Easy to Use
Since aluminum welding is a slightly different process, it is essential to select a welder for aluminum that is easy to use. When you can’t operate and use a welder easily, you will never get a precise result.
Easy to use aluminum welders will assist you in accomplishing a welding project.
What is the easiest way to weld aluminum? Can You Use a MIG Welder for Aluminum?
As we stated earlier……
You need to be a bit tricky when welding aluminum with a MIG welder. It is because aluminum is sensitive to heat compared to mild steel.
With a MIG welder; the aluminum thickness has to be 14 – 18 gauge. If the aluminum is thinner than this thickness level, choose a TIG welder.
For example, a can of soda can easily be welded with a TIG welder.
While unexpected burns will happen when you weld aluminum using a wire welder, you will end up with a messy workplace by the weld puddle if your movement is slow. Carefulness is a must when welding thin aluminum pieces.
Can Stick Welders weld aluminum?
When welding mild steel using MIG, the MIG gun’s slow enough movement is necessary to get deeper penetration. Yet, with aluminum, the welded poodle resembles wet foil.
However, the welded poodle of molten red hot aluminum will not be visible in the beginning. When the weld puddle of aluminum gets too hot, you will get that feeling.
Last one but not least……….
Keeping the workplace neat and clean is necessary, and it can be done only by carefulness.
While selecting the best welders for aluminum, learning enough information is mandatory. You can buy an ideal welder for your project only when you researched and read the expert’s reviews. Otherwise, you will be misguided.
This guide discusses adequate information, and hopefully, it will let you pick the right welder. Your aluminum welding project will never be a complicated and challenging task with the ideal device.
Good luck ya’ll!
