Things to Сonsider
Except if you are a super-experienced welder who knows the in-and-out of welding, there are chances that you will need further help than the one we have provided. Knowing that, we have included the comprehensive buying guide below to make things easier for you.
What is a TIG welder?
Also referred to as Gas Tungsten Arc Welding, TIG welding is one of the most popular techniques. Having originally come into existence in the 1930s, TIG welding was primarily used then for welding magnesium, especially in the aircraft industry. The process involves fusing metals together by producing an electric arc between the metal base and a non-consumable tungsten electrode. With this, it does not melt whatsoever. In addition, the torch generates a stream of inert gas to protect the electrode, the weld pool, and the molten metal from air contamination.
For TIG welding you can choose any welding position. The machine can be manual, semi-automatic or fully automatic, usually depending on the application. The welding material reaches the melting state by the arc maintaining temperatures of about 4,530 degrees Fahrenheit. You can select any welding position for TIG welding. Besides, the tool can be fully automatic, semi-automatic, or manual, usually based on what you want to use it for. The material gets to its melting state by the arc, while maintaining a temperature of around 4,530 degrees Fahrenheit.
How to use a TIG Welder?
When using TIG welder, you have to be extremely skilled as there are three things you need to control – the torch, the foot pedal, and the filler rod. This, however, allows you to have more control over the heat input since these elements can be adjusted to achieve more precise results. This process involves utilizing an electric TIG torch for striking the arc with one hand while using the other hand to use a filler rod to stuff the filler metal into the weld pool.
Meanwhile, there is also the foot pedal, which is designed to control the current produced by the TIG welder. Thus, you can set the maximum current on your welder and then change it amperage with the foot pedal. You can see this process allows for a lot of flexibility, which enables you to start the process slowly and helps to avert thermal shock within the metal. You have to ensure your clamp is affixed to your metal workbench or workpiece when you set your welder up.
You will have to discharge Argon gas via the TIG torch to protect the weld from being contaminated. You will need to connect a regular and a gas bottle for this, though. Also, ensure you select the ideal welding gas because your MIG bottle will not be proper.
Advantages of TIG welding
If you know a thing or two about welding, then there are chances that you know the kind of advantages that TIG welding has over other techniques. The non-consumable electrode increases accuracy significantly in any welding procedure that requires great details and sophisticated handling. Even though it can generate premium-quality welding products, the TIG welding technique is also incredibly affordable, which is really surprising. However, this could sometimes depend on the tasks at hand.
Another benefit of the TIG technique of welding we will be mentioning is the purity of the produced metal. As stated previously, this technique utilizes an electrode with a very high melting point. Besides, it doesn’t melt and turns to a part of the metal base, which subsequently means the joint base will only include the metal parts of the real metal bases.
Features to consider when choosing a TIG welder
As you must have seen, most TIG welders are similar, but you don’t need to allow this to get you confused. To prevent confusion from setting in, we urge you to read this guide to get a clearer picture. Below are the most important factors we took into consideration when selecting the best TIG welders:
When selecting a TIG welder, you must know your primary input voltage requirements. Here, know that you have three primary options when it comes to this. The first one is a 120-volt input, which actually is your normal home power supply. The second one is a 240-volt input, which needs a generator, while the third one is a 120-volt/240-volt input, which is a combination of both.
If you are only welding from your workshop at home, you should be fine with a 120-volt TIG welder. Meanwhile, the 120/240-volt input gives maximum flexibility, thereby allowing for more power. Bear in mind that a 240-volt input will be too much if you will be using the tool from your home power supply.
When buying a TIG welder, it is very crucial to take the amperage range into consideration. Usually, TIG welders feature low amperage. This may appear like a downside, but it actually helps in various welding projects in reality. Unlike thick sections or bars that require high amperage, low amperage is needed for thin metals.
When working on thin materials, a TIG machine that reaches as low as five amperages would be ideal. An example of such machines is the Weldpro Digital TIG 200GD TIG Welder. Aluminum, on the other hand, has a tendency of needing a lot more power and will need a machine that packs 200 amperages at least, such as the PRIMEWELD TIG225X TIG Welder. Basically, the broader the range, the more the numbers of applications the machine can be used for.
Maximum material thickness
You also need to take the maximum thickness of the material you will be welding into account. This determines the current range of the machine you have to purchase. A machine with a higher current range can weld thicker materials. Keep in mind that while a powerful welder can be turned down, a low-power tool can never be pushed to pass its limit. Therefore, if you are unsure about the thickness you will be dealing with, you better choose a powerful unit.
For welding hobbyists and new beginners, a duty cycle around 20% is more than enough in most cases. Duty cycles of about 40% or 60% are often sufficient for TIG applications in industry and construction. While professional industrial welders require a 100% duty cycle, due to the long weld time that they could lose while waiting for a welder to cool off.
For beginners and welding hobbyists, a duty cycle of about 20 percent is sufficient most times. Duty cycles of around 40 percent or 60 percent are usually more ideal for TIG projects in industries and construction sites. Whereas, industrial welders need a 100 percent duty cycle, thanks to the long welding time they could lose while waiting for a machine to cool off.
If you mean to use the machine in the same place, this may not be an issue. However, if you plan to be moving it around according to the project you’re working on, then you need to find a portable model, such as the HITBOX TIG 200A welder. This kind of machine allows for easy mobility when you need to move to different regions. Smaller, inverter-based welders are fairly easy to use, thereby offering a lot of versatility.
When working on small projects that don’t need a longer duty cycle, a small welder is convenient. After considering the power output and duty cycle, portable has to be the next thing on your list. For households where a large-scale welder isn’t needed, choose a small machine that is capable of moving easily around when carrying out welding projects.
The weight, a lot like dimensions, is another important feature you need to take into consideration. Again, the best thing is to look for a machine that is as lightweight as possible, to aid mobility. However, we would also note that most of the most powerful models are usually very powerful, so keep in mind that you may need to make a compromise here. Meanwhile, the most lightweight model on our list is the HITBOX TIG 200A TIG welder, which isn’t surprising considering that it’s also the most portable.
While it’s not common to have issues with power tools, we understand that these machines are usually very expensive, and it’s always a good thing to acquire a unit that’s backed by a warranty from the manufacturer. The best brands usually go the extra mile when it comes to warranties. Most times, they back their products with three to five-year warranties, which shows their level of confidence in their products.
The Fan-On-Demand feature is very important when looking for the best TIG Welder. The feature allows the fan on the machine to run only when it’s needed, which helps reduce the amount of debris/dust that the machine pulls inside.
A TIG welder can work with a wide range of materials, which include welding stainless steel, mild steel, aluminum, and other metal materials.
Most powerful welders are usually too powerful for small jobs, but there is nothing like that with the PRIMEWELD TIG225X TIG Welder. With its wide current range, advanced technology, and super-durable construction, it would be an unwise thing to bet against this incredible welder. Whether you’re a professional who’s always dealing with heavy-duty projects or just a hobbyist who only works small welding projects around the house, this model from PRIMEWELD is the best TIG welder for every situation.
The Miller Multimatic 215 TIG Welder grabs the second spot, which is down to its wide current range, lightweight construction, and a variety of advanced features. This model gets a lot of raving reviews, and they are all deserving, in our opinion.
That means the Weldpro Digital TIG 200GD TIG Welder could only take the third spot, but that doesn’t really mean it’s significantly behind the Miller model. Like the top two models, this one also has a wide current range, which makes it versatile. Plus, it has an almost impeccable design, which should aid its ease of use
