There are many different ways to weld aluminum.
One way is to weld aluminum without the use of any gas. Gas is supplied through a hose under pressure from a gas bottle. It is used in order to get enough heat to melt the metal, and it also keeps the metal from cooling too fast or keeping the metal at the correct temperature during welding.
Another way is to use a plasma cutter. This type of equipment uses a special nozzle that shoots out a stream of hot electrons (plasma). Using this type of equipment, you can cut through aluminum as well as many other metals including stainless steel and titanium.
You can even purchase all-aluminum welding rods that are pre-welded for you at home. This is an easier way to get started, but if you have a lot of work to do, you will eventually need to purchase a better quality welding rod.
In this article, we will go over the different types of aluminum welding rods that are available and some of the advantages and disadvantages of each type.
Welding Aluminum Without Gas
The equipment used for this type of welding is known as an arc welder. This is a device that uses electricity in order to produce the heat needed in order to melt aluminum. The arc welder has both a power source as well as a clamping mechanism. It attaches to either a 110V or 220V power outlet and has an adjustable clamping mechanism for various thicknesses of aluminum.
The clamping mechanism allows you to clamp to a variety of different metals, and it is also adjustable to accommodate different thicknesses. The arc welder heats the aluminum up to about 3,000 degrees and then passes the molten metal through the welding rod.
You will need to supply your own gas. This can be supplied either via a hose connected directly to the fire box in the back of your aluminum welder, or you can connect it via a gas bottle that is connected under pressure.
The gas source can be purchased at any home improvement store, but you will have to get a bottle with a gauge that measures PSI (pounds per square inch). It can also be purchased on Amazon for an extremely cheap price.
If you are going to buy the gas bottle, you may want to pick up a few extra bottles of gas just in case.
Advantages
1) You have the freedom to weld aluminum without the use of gas. There are two main advantages of using this type of welder. First, it is much cheaper than using a gas welder. A good quality arc welder can cost only a few hundred dollars or so and will last for years if not decades of welding. The second advantage is that it is much easier to use than a gas welder. It requires less training and there is no need for any special tools or accessories. You can weld aluminum using only your hands and a few tools that you will probably already have around the house.
2) You can weld aluminum using this type of welder even if you do not have the correct electrical outlet to power it. The cordless arc welder is very powerful and will weld steel and many other types of metals.
3) It is easier to start welding aluminum with a tool like this than with a gas welder. You do not need to get all the different wires, clamps, and gloves in order to start welding metal. This allows you to start learning how to weld aluminum right away so that you can use it as an alternate way to weld other types of metal.

1) The lack of gas means that you cannot easily weld aluminum on a large scale. You have to be able to heat up the metal for a long period of time in order to weld aluminum without gas.
2) It is not as efficient as using a gas welder. The arc welder is quite expensive, and it will take you much longer to weld the same amount of metal with it. It takes much more time to run out all of the electricity that is in the arc welder than it would with gas. This means that you will have to use more welding rod with a gas welder, which can get very expensive if you purchase it in bulk.
3) The welding rod itself can become too hot and start cracking if you are not careful. You need to make sure that you do not leave the welder unattended while welding aluminum.
Conclusion
The arc welder is a great way to weld aluminum at home without the use of gas, but it is much more expensive than using a gas welder. It will take you significantly longer to weld metal with this type of welding tool.
The arc welder is also much easier and more efficient if you want to start welding aluminum right away. It can be used on many different types of metals, and you do not need any additional tools or accessories in order to use it.
It will also be much more difficult than using a gas welder because you do not have any access to a gas source or hose like you would have with a gas welder. You will need to get your own gas bottle or connect it via a hose.
If you are going to be using it on a large scale, then you will probably want to buy a gas welder instead of an arc welder.
The gas welder is going to be the more efficient and easier way to weld aluminum. It is going to allow you to make large amounts of aluminum in a short amount of time and will be much more economical to use.
