Aluminum is a material which is used for a wide range of purposes, from building houses to making automobiles. There are several types of welders that are designed specifically for aluminum welding. These welders have features that make the process easier and more effective.
If you are going to use an aluminum welding machine, it is essential to know some basic dos and don'ts. You will need to consider some key features of the machine, as well as the application. The best way to learn how to weld aluminum is to practice. This means doing some trial and error, as well as researching the different options available.
Some of the features that you will need to look for in an aluminum welding machine include a good duty cycle. A 60% duty cycle is generally adequate, but if you are working with a high-quality machine, you should aim for a higher percentage. This is because the high energy pulses allow for longer arcs, which helps the weld puddle to cool down.
An alternating current system is also a good option, as it prevents contamination in the weld pool. This type of power source is especially beneficial for aluminum welders. It also has the benefit of not requiring mechanical wire feeding.
Another feature to look for in an aluminum welding machine is Waveform Control Technology. This technology alternates between high and low energy pulses to produce a rippled bead appearance. Also, it gives excellent control over the arc characteristics.
If you are considering purchasing an aluminum welding machine, you will also need to decide whether you want a MIG or TIG welder. While a TIG welder is a slower, less-effective way to weld, it is a better choice for thinner material. For example, if you are welding a 1xxx aluminum alloy, a TIG welder is the way to go.
Aside from these two, you will need to consider how much you want to spend on your new aluminum welding machine. There are many different models on the market, and each has its own unique set of benefits. However, if you're on a tight budget, you may be interested in a machine that is less expensive.
One of the easiest ways to weld thin materials is to connect a spool gun to a MIG welder. Alternatively, you can use a band saw for this purpose. Be sure to clean the edges of the sheet metal before welding. That's because it will become covered in a layer of aluminum oxide as it's being welded, and this should be removed before the metal is cured.
Lastly, you will need to choose the best spool gun. Having the right spool gun will make the job of welding aluminum much easier, and will prevent burn through. Using a Teflon insert will improve the way that the aluminum wire slides into the holder, but you can skip this step with the right spool gun.
When it comes to aluminum welding, there are other techniques you can use, such as using a plasma cutter. A plasma cutter is a great tool to weld sheet metals, but it can cause discoloration.
