How To Choose an Ideal TIG Welder – Buyer’s Guide

Before we get started with our list, it is important to talk about things you should look for in a TIG machine, especially if you typically work with thinner metals.

Always try to opt for user-friendly and simple designs. For example, accessible controls and a foot pedal to control amperage can make your projects much easier.

Prioritize a wide amperage range. This will extend the scope of materials that you will be able to weld. Performance at low amperage will allow for better arc stability and improved crater filling.

A TIG welder that provides both AC and DC output will also widen the spectrum of metal types that you can weld. Similarly, AC balance control is an important feature that will allow you more application versatility.

Heat control is another important pro that will make working with thinner metals more practical. Additionally, try to go for a high duty cycle, which is a TIG welder’s ability to maintain a specified output in a ten-minute time frame.

When buying a TIG Machine, it is also critical that you keep potential buying pit-falls in mind.

Firstly, it is important that you consider how to make a monetary gain with your welder. Refrain from purchasing heavy-duty equipment if you are a hobbyist, but be realistic about your potential power needs. Spend a little more now to ensure that you don’t limit yourself in the future.

Industrial TIG welders may require additional cooling equipment to optimize their output and duty cycle. This can pose a problem if you didn’t take these additional costs into account. Before buying, make sure that you consider the welder’s cooling requirements.

Some TIG welders come with AC capabilities to allow for delicate metal working. If you are sure that you will never weld metals like magnesium or aluminum, avoid these products and buy one that is more affordable.

Incorrect input voltage can render your unit unusable, so make sure that your power infrastructure is compatible with the welder that you want to buy. To stay on the safe side, only consider welders that operate on both 110v and 220v.

Important Things To Consider When Buying a TIG Machine

Whether you are a hobbyist or professional welder, it is important that you buy a unit with specifications and performance that is suited to your needs. To make sure that you buy a machine that is right for you, consider the following:

Quality and Appearance of Welding Job

When it comes to welding, quality and speed are, in a way, mutually exclusive. When you are in the business of high-end or precision manufacturing of, say, silos instead of mass production, a TIG welder with AC capabilities is your best option.

Thickness of Metal

If you typically weld metals that are thin and delicate, it is important that you opt for a unit that has a high performance at low amperage. TIG works best for thin metals. On the other hand, if you mostly work with metals that have a thickness of ½” or more, MIG or stick welding is best.

Combination AC/DC

If you work with steel and stainless steel, you will get the best performance and results with a DC output. As far as magnesium and aluminum welding are concerned, however, you have to make use of the AC output from the power source. To ensure maximum versatility, consider purchasing a combination AC/DC machine.

Power Requirements to TIG

The power source of TIG machines can be DC (direct current), AC (alternating current), or AC/DC.

DC power delivers a concentrated arc with the bulk of the heat contained in the workpiece. When you use a DC output, you have to make sure that the work surface is clean before you start welding; you should also ensure that there is an efficient gas shield. DC is primarily used for working with harder materials like steel.

Certain metals like aluminum and magnesium contain a tenacious oxide film on their surface. To weld these self-oxidizing metals, you need a welder with AC capabilities. Because the current alternates between positive and negative, the periods of electrode positive remove the oxide and keeps the surface clean and expose the base metal.

It follows, then, that if you have a machine that employs either AC or DC output, you are limited in terms of the material that you can weld. To eliminate this problem, it is advisable that you get a welder that delivers both AC and DC. This will ensure maximum application versatility.

To control the speed at which the AC current alternates from positive to negative, make sure that your TIG welder is fitted with balance control. Controlling the balance of AC operation will allow you to change the length of your welding and cleaning cycles according to the level of oxidation on the metal.

  • High-end TIG welder, perfect for DIY projects
  • Suitable for welding oxidized metals
  • Easy handling and operation
  • Intelligent digital control


  • Doesn’t feature a wide amperage range
  • Limited in terms of metal thickness


The type of material and electrodes that you will be using determine which current you should use. A common mistake people make when operating a TIG welder is to use the wrong current. For metals that have a layer of oxide on the surface, like magnesium, it is important that you switch to AC.

If your equipment is not geared for AC, you will not be able to weld the oxidized steel. Any other steel can be welded with a DC power output. If you are unsure of which current to use, cut off a piece of metal and test your different settings to ensure that your weld is at the correct strength level.

Your amperage range is also significant when it comes to the thickness of the metal that you are welding. When the range starts above 10A, chances are that you may warp the thin metal. Similarly, an Amp range that is limited to, say, 50A can make welding steel that is ¾” thick more difficult.


Optimal portability can be a big productivity boost and time saver, especially if you engage in overhead welding or when you have to work on a roof. Your portability needs depend on your setup and how you use your equipment, but there are some common mistakes that people make in terms of portability.

The most common mistake is tugging at the welder to move it closer. This can be dangerous and carry the risk of damaging your unit. Rigging up a service trolley can make it easier to handle and move your machine around.

Another mistake is having welding cables that are too short. If you work in a fixed setup or on a bench, this is not a problem, but if you switch to different job sites, make sure that your cables are as long as possible. Try to make use of trailers and storage solutions to keep your equipment and cables organized.

Cooling Control

A common mistake that welders make is to not preheat the welding surface. Preheating prevents cracking as it prolongs the cooling rate after welding. The type of metal and its thickness determines the preheat.

It is also important to administer temperature control, especially when you are working with thin or delicate materials. You typically control the weld temperature by means of pulse welding. This is an alternating lower and higher peak current that allows for a stable arc.

Effective cooling control will ensure that your welding job has a neat appearance and a sound structure. When the welding temperature is controlled, you will be less likely to see cracking or disintegration when you are done.


Lotos CT520D
