How To Choose The Best TIG Welders

If you would like to choose the right TIG welders, you can refer to the following guide highlighting what you need to know about these welders.

Controls and protection features

Thermal protection should not be forgotten when finding a good TIG welding machine.

One of the best methods in order to regulate the input of the weld without losing penetration would be to use a pulse weld, allowing it to alternate between lower and higher currents.

More so, you can make a better decision by choosing a welding machine that comes with overload and thermal protection features, which can protect the machine from damage, ensuring its longer lifespan.

That said you could have peace of mind that you’re getting the most of your spending.

Metal thickness

If you’re commonly working with delicate and thin metals, you should look for a unit that can perform smoothly at a low amperage range.

For example, know that TIG will work for thin metals well, but stick or MIG welding will be for you if you’re working with at least ½ inches.

Portability and compact

When buying a device for use in the same location over again, you don’t have to worry about portability. However, it will be a different story if you would have to move from one project location to another due to multiple projects.

You can use two basic methods in order to use a TIG machine as a portable welding machine, and these two will include using inverters or engine-driven welders.

For example, inverters will weigh about 10 lbs and operate at 115V and 230V currents. These inverters are power converters that will let the machine to be lighter and smaller in size than traditional bulky models are.

Pulsed welding

Know that you need to control the heat you’re applying to metal when it comes to TIG welding. The good news is that the latest models are with inverters that are able to create more pulses per second. These can offer up to 5,000 pulses per second.

For example, the higher level of pulsing rate will lead to a stronger weld because it allows you to take more control over the weld puddle.

In this case, you will be able to remove less material while also being able to travel faster along the metal you’re working with, resulting to a clean weld.

Amp rating and range

It is one of the most important factors to remember when finding the welding machine for your skill level, situation and types of welds you normally work with.

You must always consider the amp range and at the same time figure out which one is ideal at a price that you can afford.

For example, if you are commonly working with a wide range of metals, buying a welding machine that has very limited amperage will affect your output and limit what you can weld.

Remember, a welding machine that features a range between five and 230A will do just fine in terms of welding thinner types of metals that include more than 1/4 in. thick aluminum or 24-gauge stainless steel.

However, you must also know that aluminum will require a higher amp versus welding stainless and steel materials.

So for that matter, using a machine that can’t supply at least 200 amps will limit the max possible welding thickness of 1/8 to 3/16 inches aluminum.

Without even saying, a higher range for amperage also means more applications for which you can use your machine.

AC/DC combination

If you’re working with stainless steel and steel, you can depend on a DC output machine. But if you also need to work with aluminum and magnesium, you will need an AC output.

However, if you want a more versatile machine, you might want to opt for one that can work on either AC or DC outputs. It is what you might want if you require more functionality for your welder.

An AC/DC combination for your welding machine also makes it more versatile and not limiting you from working on different types of metals and projects.

Remember these things when comparing and weighing your options in choosing a TIG welder suitable for your situation, common projects and types of metals you’re commonly dealing with.


There you have what to know about the finest TIG welders on the market right now. Each of them has their strengths and features that makes one better than the other is, so you have to take a look at each closely.

Finding the right TIG welding machine will help you accomplish your project with a sound structure and clean result.

It will also give you that rewarding feeling for finishing your projects with precision and ease. It will also allow you to weld different types of metals, which include aluminum, stainless steel and aluminum alloy, to name some.

In addition, the right machine can be versatile for car repairs, works around the house and other uses like commercial or industrial from select models.
