Lincoln Electric K5126-1 TIG welding machine – Best TIG Welder for Home Use
It is a pity that such a respected welding brand is so low on our list. However, the Lincoln Electric TIG 200 TIG square wave welder is inadequate in many vital areas that we couldn’t raise.
This is a well-designed machine, with smart placement of the various settings and a decent foot pedal and flashlight. It’s also easy to use the machine. The manual is straightforward but a bit redundant as it is very little you need to know to run it correctly.
However, we don’t like the price. It only runs at 200 amperes and has minimal options for adjusting the settings, including the most current that runs continuously at 15 seconds. Some customers who receive the machine are either unable to use it because it arrives broken or stops working, but it breaks a little later.
Lincoln usually replaces it under their warranty system, but they don’t have the best customer service, making the experience less enjoyable. Given the price, this is not acceptable for such a well-known brand. We recommend investing in a more expensive Miller machine that is guaranteed to be reliable.
Before we start our list, it’s essential to talk about things to look for in a TIG machine, primarily if you typically work with thinner metals.
Always try to go for user-friendly and straightforward designs. For example, accessible controls and a foot pedal to regulate the amperage can make your projects much more straightforward.
Give priority to a wide range of currents. It increases the choice of materials that you can weld. A TIG welder that supplies both AC and DC power also expands the range of metal types you can weld. Also, try to achieve a high duty cycle.
This is a TIG welder’s ability to maintain a given performance level over ten minutes. When buying a TIG machine, it is also essential to consider possible pitfalls.
Spend a little more now to make sure you don’t limit yourself in the future.
This can be a problem if you haven’t factored in these additional costs. Before purchasing, consider the welder’s cooling needs.
Some TIG welders have AC functions for delicate metalworking. If you are sure that you will never weld metals like magnesium or aluminum, avoid these products and buy cheaper ones. So make sure that your power infrastructure is compatible with the welding machine you plan to buy. To be on the safe side, only think of welders who work with 110 V and 220 V.

Important points when buying a TIG machine
Whether you are a hobbyist or a professional welder, you need to buy equipment with specifications and performance that meet your needs. To make sure you are buying a machine that is right for you, consider the following:
Quality and appearance of welding work.
When it comes to welding, quality and speed are mutually exclusive. If you like high-end or precision manufacturing of, e.g., silos rather than mass production, an AC capable TIG welder is the best choice.
AC / DC combination
When working with steel and stainless steel, you will get the best performance and DC output results. However, when welding magnesium and aluminum, you must use the AC output of the power supply. Consider purchasing an AC / DC combination machine for maximum versatility.
When welding thin and delicate metals in general, you must choose a unit that can perform well at low amps. TIG is best for thin metals. However, if you work primarily with metals 1/2 inch or thicker, MIG or stick welding is best.
We chose the Weldpro 200GD as our pick for the best TIG welder for the money. It has more features than any other device on this list, and user reviews have been overwhelmingly positive. The 3-year guarantee and the AC / DC capability seal the deal for the big yellow AHP machine.
The Eastwood TIG 200 and the Primeweld TIG225X are attractive alternatives.
Common mistakes when using a TIG machine
AMPS – AC / DC
The type of material and electrodes you use will determine the current to use. A common mistake people make when using a TIG welder is using the wrong current. For metals with an oxide layer on the surface, such as magnesium, switching to alternating current is vital.
If your equipment does not have AC capability, you will not be able to weld rusty steel. Any other steel can be welded with a DC power supply. If you’re not sure what current to use, cut a piece of metal and test the different settings to ensure your solder has the right level of resistance.
Your current range is also essential when it comes to the thickness of the metal to be welded. If the range starts above 10 A, the thin metal is likely to warp. Likewise, a limited amperage such as 50 amps can make it difficult to weld thick steel.
A common mistake of welders is not to preheat the weld surface. Preheating prevents cracking as it increases the cooling rate after welding. The type of metal and its thickness determine the preheating.
It’s also essential to manage temperature control, especially when working with thin or delicate materials. As a rule, the welding temperature is controlled by pulse welding. It is an increasingly low peak alternating current that allows a stable arc.
Efficient cooling control ensures that your welding job is neat and has a solid structure. With the controlled welding temperature, you’re less likely to see cracks or disintegration when you’re done.
Optimal portability can mean tremendous productivity and time savings, especially if you need to weld at height or work on a roof. Your portability requirements will depend on your setup and how your devices are used. However, there are some common mistakes people make when it comes to portability.
The most common mistake is to bring the soldering iron closer. It can be dangerous and can damage your device. Installing a service cart can make it easier to handle and move the machine.
Another mistake is welding cables that are too short. If you are working in a fixed configuration or on a bench, this is not a problem. However, if you are moving to a different workplace, make sure your cables are as long as possible. Try using beacons and storage solutions to organize your devices and cables.
