    Buyer’s Guide (Tips & Tricks)

    The Benefits of a TIG Welder

    TIG welding goes by a couple of different names. You may see it referred to as Tungsten Inert Gas (TIG) welding, which is commonly used by industry professionals. Or, you might see the technique being called Gas Tungsten Arc Welding (GTAW). Regardless of what name is being used, this method differs dramatically from other techniques. One of the biggest differences between TIG welding and MIG welding or stick welding is the lack of flux and consumable metals.

    You see, TIG welding utilizes tungsten electrodes. Tungsten has the highest melting point of all metals at 3,410 degrees Celsius. As a result, there’s no need to provide a constant feed of sacrificial metal. Instead, the tungsten electrode remains intact while it forms an arc to the base metal. In an instant, a molten weld pool is formed. You can then feed a filler metal into the pool to fuse the two metals together.

    To address issues that may come from a lack of flux, an inert gas is used to protect the tungsten electrode and weld pool. Typically, argon is the gas of choice. It helps to prevent oxidation. Because no flux is used, the finished weld is slag-free, clean, and strong.

    While TIG welding does require two hands and great dexterity, the finished product has higher purity. Plus, you’re provided with more control. This makes it a suitable alternative to other welding techniques when precision is a top priority.

    TIG welding is commonly used for bonding metals like stainless steel, aluminum, copper alloys, and magnesium. In fact, the process was first developed for non-ferrous metals that react quickly to oxygen, such as aluminum and magnesium. With that being said, the technique can be used on most metals.

    It has become the go-to choice for many metal workers due to its versatility. TIG welding torches can operate on lower amperage settings than most equipment. Some of the best TIG welders also offer precise heat and amperage controls to make switching between different metal surfaces more efficient.

    Factors to Consider

    Despite all of the versatility that TIG welders offer, some tools are better at specific tasks than others. Whether you’re new to TIG welding or you’re a seasoned pro looking for new equipment, there’s a lot to consider when you’re shopping. The following considerations can determine what your new welder is capable of doing and how well it gets the job done.

    Input and Output Power

    When it comes to power, there are two main factors to consider. These include amperage and AC/DC power capabilities. In most cases, TIG welders do just fine on AC. AC power is suitable for low-density metals like aluminum and magnesium. However, if you’re working with thick base metals or harder materials like stainless steel, the welder will fair better with a DC current.

    Luckily, most TIG welders give you the opportunity to use both. Not only that, but high-quality tools let you tune the current settings to achieve the optimal weld.

    As for amps, the higher the output range, the better. More settings provide you with greater flexibility in what you can do. Generally, TIG welders can output between 5 and 250 amps. Though, you can find models that can do more. Of course, robust amperage controls are a must-have. Your welder should have stable performance regardless of the settings you’re working with.

    Duty Cycle

    The duty cycle of a welder refers to how long the equipment can produce a steady current. All welders need time to cool down. Pushing the machine past its duty cycle can result in damage and possible safety issues, so it’s important to consider how you will be working.

    Longer duty cycles are most prevalent in industrial settings. If you’re looking for a welder that you’ll use at home infrequently, you can get away with a lower duty cycle.

    This figure is typically represented as a percentage of the total active time of the welder, which is 10 minutes. So, if the welder has a duty cycle of 30 percent, that means that it can run for 3 continuous minutes during that cycle. After that, it needs to rest for 7 minutes before you can work again.

    Control Systems

    The way that you can control the welder can ultimately affect your workflow. As we mentioned earlier, TIG welders are capable of switching between amperage settings easily. Some use a thumb switch while others take advantage of a foot pedal. Foot pedals are considered to be the most convenient. Remember, a TIG welder requires both hands to operate. Having the ability to make heat adjustments with a flick of your foot can make all the difference.

    Many welders use digital displays as well. They can be useful for following manufacturer recommendations and preferred settings. But, they don’t offer the fine control that a manual switch does.

    Protective Features and Cooling

    Next, let’s talk about safety. The best TIG welders are designed to prevent potential safety issues for you and the material you’re working with. One of the most useful is thermal overload protection. As the name would suggest, this feature helps to prevent the welder from overheating. It’s directly related to the machine’s duty cycle. Many models will automatically stop the current and shut the welder off once it’s used beyond the duty cycle. This ensures that the cooling system has enough time to prevent overheating.

    Speaking of cooling systems, there are two options available. These include air-cooled torches and water-cooled torches. If you plan on taking your welder with you from job to job, air-cooled machines are your best bet because you don’t have to worry about finding a water supply line. However, water-cooled torches are more efficient. These welders typically have higher duty cycle percentages and can operate for much longer.

    Convenience Features

    Extra features to make your job easier are always welcome. There are a few notable additions you can look out for when you’re searching for the perfect welder. High pulse settings are great for working on thinner materials that require greater control. Some TIG welders offer as much as 5,000 pulses a second. To make things even better, you can often set up pulse settings with a foot pedal. That way, you can control heat and avoid burning through your metal.

    You can also find TIG welders that offer a built-in plasma cutter and stick welder. These features aren’t a requirement, especially if you already have separate machines. However, the added functionality these extra bring can save you a lot of time as you work.


    If you are constantly on the go, portability is an important thing to consider. TIG welders vary dramatically when it comes to size and weight. On the smaller end of the spectrum, you can find tools that only weigh 20 to 50 pounds. These options are often equipped with handles for easy transport. Larger welders can weigh well over 100 pounds. They’re not suited for welders on the move. Though, they can be used with carts or durable caster wheels for movement around your shop.

    It’s important to consider how the size and weight of your welder will affect performance. There’s a fine balance between portability and power. Smaller machines have to sacrifice on output and duty cycle due to the size of the transformer. On the other hand, larger models can usually accommodate bigger jobs.

    User Friendliness

    Last, but not least, there’s user-friendliness. TIG welders are advanced machines that require plenty of know-how and a steady hand to operate efficiently. With that being said, some welders are designed to be accessible to workers of all skill levels. These options often have automatic features and digitized controls.

    Automatic features are ideal for those who don’t have much experience with TIG welders. All of the settings are predetermined and ready to go, minimizing the amount of time you have to take figuring things out. Plus, they are engineered to react accordingly to any performance issues that come up. This ultimately decreases the overall maintenance involved with owning a welder.

    The same goes for digitized controls. Welders with digital readouts let you keep a close watch on how the tool is performing. They’re easier to follow the recommended settings and are virtually fool-proof when it comes to finding the right power settings. Of course, with automation, you’re sacrificing control. If you’re a professional who knows the ins and outs of what a TIG welder can do, you won’t have any issues using a manual welder.


    While any one of the welders on this list can serve you well, the AlphaTIG 200X from AHP is a cut above the rest. When considering performance and versatility alone, it’s the clear winner. Sure, it may not have a built-in plasma cutter like other devices, but it makes up for that shortcoming by giving you complete control over how you weld. Let’s face it, welding jobs can come in all forms and capacities. Having the ability to adapt your tools to accommodate all of those jobs makes all the difference. The AlphaTIG 200X is one of the best TIG welders because you can manipulate every aspect of the current you’re using. Not only can you choose between AC and DC, but you can select the shape of the wave, pulse frequency, starting amps, ending amps, and so much more.

    When compared to products from Everlast, Amico, Lotos, and even Miller, the AlphaTIG 200X is in an entirely different league when it comes to versatility. Even the Lotos TIG200ACDC 200A, with its square wave inverter, doesn’t have as many current options as the AlphaTIG 200X. This machine can take on a wider range of materials and is simple enough for even beginners to approach. On top of all of that, it’s much more affordable than welders that can only perform a fraction of the jobs. Ultimately, the AHP TIG welder checks off all of the boxes. It has a large amperage range, high duty cycle percentage, and is portable enough to take with you on the go. What’s not to like?
