Things to consider before buying a welder for aluminum products:

Aluminum is quite a special sort of metal that is distinct from other pieces. So, you will need proper equipment and skills as such it requires different welding techniques. Aluminum has a lower melting point compared to steel. Moreover, as service temperature decreases, the strength of aluminum increases.

Choosing a filler metal is a critical issue in welding aluminum products. Proper filler metal selection can be done depending on the characteristics of the aluminum selection chart. In the case of aluminum welding, we suggest to clean the workpiece properly, use a stringer bead, remove the oxide layer, and monitor the temperatures frequently.

Apart from these, to let you choose a worthwhile welder, we have listed some of the prominent considerations before buying a welder for aluminum products.

Process:

MIG welding with Aluminum

Metal Inert gas welding, popularly known as MIG is a welding process where an arc is maintained between consumable electrode and work-piece. MIG is the best technique for beginners and is also a good way to weld aluminum.

Thick aluminum sheets can be welded conveniently with MIG welder whereas materials thinner than 14 gauge might require specialized pulsed MIG. If you are welding using a shielding gas, we recommend 100% argon that would be the best option for MIG welding with aluminum. A spool gun is commonly used to feed aluminum which removes the problems of birds nesting.

TIG welding with Aluminum

Tungsten Inert Gas welding is a versatile welding process that requires a lot more knowledge, techniques, and practices. However, TIG is the most popular welding technique for aluminum.

As TIG welding can prevent overheating problems, aluminum can hold the heat for more time. Though TIG welding might require some master skills, the ultimate procedure results in beautiful welds. Thinner or thicker aluminum workpieces, TIG welding applies to all. Make sure to clean your welding surface before welding aluminum for a cleaner, stronger welds. A wire brush or chemical etch process can be used to clean aluminum pieces.

Metal thickness:

Aluminum has a low melting point and this requires lower heat transfer for a longer time. Amperage settings of a welder determine the heat to be produced. We recommend buying a welder whose amperage has the sustainability of working with certain thicknesses. According to professional research, 1 amp of power is needed to melt 0.001 inches of Aluminum. Simply put, to weld a 1/8 inches of aluminum, you will require 200 amps of current.

For thinner sheets of aluminum, purchase a machine with a low amperage setting. This might be between 15-20 amps.  However, amperage is highly dependent on your workpiece and its thicknesses.

Duty Cycle:

The factor you should pay the most important in choosing the best welder is, duty cycle. Duty cycle refers to the time a welder can work continuously before it is turned off. A welder with a 60% duty cycle at 100 amps means that a welder can operate for 6 minutes at 100 amps without overheating. For TIG welding, a 40-60% duty cycle is recommended for most tasks.

Voltage:

Power outputs may vary from one welder to another. If your activities are limited to household, hobby projects 115V and 40V power input welder is more than enough. We suggest considering the amperage setting along with the power ratings for achieving the best results. Also, it is better to purchase a unit with more amps so you can readily work on small and big projects.

Price:

Price is a significant factor to consider before buying a welder. There are many welders within an affordable range whereas expensive professional-level ones too. We have listed some of our affordable welder for aluminum such as LOTOS Aluminum Tig Welder which offers exciting features within a little buck. Always keep the budget in mind to keep yourself safe from unplanned decisions.

Frequently Asked Questions (FAQ)

Q: Which is the best kind of welder for Aluminum welding?

-Tungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTAW) is the best process for welding aluminum. This process eliminates the need for mechanical wire feeding, which is a bonus point. Also, TIG welding is cleaner than other processes that prevent aluminum from contamination.

Q: Is it difficult to weld aluminum?

-It is perceived by many people that aluminum welding is difficult. But in reality, rather than difficult it’s a different welding process. Once you get a handle, it feels like a breeze.

Q: Which voltage is appropriate for welding aluminum?

-AC welding provides greater advantages over DC when welding aluminum such as greater penetration and cleaner actions.

Q: What amps are required to weld aluminum?

-The rule of thumb for aluminum 1 amp of power is needed to melt 0.001 inches of Aluminum. If you are welding 1⁄8 inches base material requires about 125 amps.

Final Thoughts

This wraps up our reviews on the best welder for aluminum products. We tried our utmost to keep the review list versatile and help you choose between many alternatives. Now, the perfect welder for aluminum would highly depend on your projects and needs.
