What’s impressive about the Lotos LTPDC2000D is that it packs a lot of features that you may only find in the high-end welding machines. However, the device comes at a relatively much more affordable price.

Besides the impressive price, the unit is also backed with Lotos’ trust. It comes with a 1-year warranty of limited warranty and 30-day return policy for a hassle-free purchase. It might not be the best warranty system, but it’s a warranty nonetheless.

The device’s dimensions are 17 inches length, 8 inches width, and 12.5 inches height. As you might’ve noticed, the welder is significantly smaller than the AHP AlphaTIG 200X. This means that it won’t eat up space in your workshop or garage no matter how small it is.

Also, it weighs only 42.3 pounds. This makes it an ideal choice for anyone who moves around a lot with the welding unit. The super-compact unit isn’t only relatively lighter than many models, but it also has a large handle that has a super comfortable grip.

As for the layout, you’ll notice that it has fewer buttons and switches when compared to the AHP AlphaTIG 200X. This makes it even simpler and more straightforward for a beginner welder.

One of the best things about the Lotos LTPDC2000D is that it isn’t just a TIG welder machine. Instead, the device works as a multipurpose welding unit that offers 3 different devices in one.

For example, in addition to being a TIG welder, it also works as a non-touch Pilot Arc plasma cutter.

The Pilot Arc utilizes up to 50 amps to efficiently cut through different types of surfaces while producing a minimal layer of slag on top.

According to Lotos, it can work even or rusty, painted, and other forms or rough surfaces. It works with a variety of metals, including mild and alloy steel, copper, stainless steel, and aluminum.

Things to Look For While Shopping for a TIG Welder Under $1,000

Now that you have enough information about TIG welders, you should also know that they come at different price ranges.

In the following section, I’ll walk you through some of the crucial points that you need to check before being your ideal welder.

Price and Warranty

Now that you have enough information about TIG welders, you should also know that they come at different price ranges.

In the following section, I’ll walk you through some of the crucial points that you need to check before being your ideal welder.

Portability and Storage

Always check the dimensions of the TIG welder and make sure that it suits you. Ideally, you need to make sure that you can store it easily.

Also, you need to check the net weight of the unit and make sure that you’re able to carry that weight around. That’s why a carrying handle is a crucial piece in any welder’s construction.

Ease of Use

No matter how many nifty features you have in a TIG welder, they’re useless if you don’t know how to use them.

A good welder must have a selection of features. However, it also needs to have a clear description of what each button or switch does.

Dual Voltage

Most households have an input voltage of about 110 volts. On the other hand, most industrial zones and machines operate on a 220-volt system.

If you’re going to use your welder in a single place, you can make it with a welder that supports a single voltage input.

However, investing in a welder that has adapters to work with both power inputs is always a great idea.

Power Efficiency

Welders, in general, consume a large amount of electric energy. Saving some energy is important whether you’re a professional who’s trying to cover their expenses or a DIY hobbyist.

Luckily, at this price range, you’ll find multiple TIG welding options that also support power-saving technologies.

For example, AHP AlphaTIG 200X and Mophorn TIG200 have an inverter technology along with a pulse width modulation to save a significant amount of energy.

Versatility

A lot of TIG welders on the market are multi-purpose welders that are capable of doing more than just a single welding method.

Some of these welders can also double as a Stick welder or a MIG welder provided that you fit them with a suitable torch.

PrimeWeld CT-520D is one of the best examples of versatility. It’s a 3 in 1 welding machine that can work as a TIG welder, stick welder, and even a plasma cutter to cut through different types of metals.

Dual Voltage and Amperage

As you know, welders require high voltage to operate. However, many brands make their welders compatible with both 110 and 220 volts. This also adds to the level of versatility and compatibility of the device.

As a rule of thumb, you need a welder that can generate up to 180 to 200 amps on the maximum voltage. This high power is able to weld at least a 0.25-inch through mild steel.

AC/DC or DC only (The Metals You Usually Weld)

Lastly, the materials you’re going to weld will have a strong impact on your choice. Welders use DC current to produce the heat required to melt the metals.

When it comes to aluminum, you’ll need an AC/DC TIG welder. Aluminum requires high heat to melt, which is produced from DC current.

However, it also requires AC to counteract the oxidation effect that results in an extremely weak final structure.

Steel and stainless steel are easy to weld because they only need high heat. That’s why you can do quite everything steel-related with a DC-only TIG welder.

However, opting for an AC/DC device will always be a good investment that allows you to worry about the metal you’re going to weld.

What Are the Advantages of TIG Welder Against Other Types?

There are different types of Arc welding methods. However, they all share some similarities in concept with slight differences that make each one of them unique.

Arc welding depends on generating high heating power due to using an electric arc at an extremely high voltage. This is where the arc welding got its name. The heat generated due to the electric arc is so immense that it’s able to melt the metals.

When that happens, you create what’s known as a “weld pool”. In this pool, the molter parts of the metals can be used to join different parts together and solidify again as they cool down.

A Deeper Look at TIG welding

Now that you know what arc welding is, it’s time to dig deeper into TIG welding and how it works.

TIG is short for Tungsten Inert Gas Welding. It’s one of the best methods for welding, as it’s known for its exemplary smoothness and clean welds. Also, the final structures are characterized by being super durable when compared to other methods.

The reason for its nomenclature lies in the material used while making its electrode and other components.

In arc welding in general, you pass the current through an electrode made of a specific metal, this current is high enough to melt both the electrode ends and the base metal you’re welding.

In TIG welding, the electric current passes through an electrode made of tungsten. What makes tungsten special is that it has a remarkably high melting point.

When a high heat current passes through it, it’ll be able to meet the base metal all the while preventing the tungsten electrode from melting along with the base metal. In some cases, you might use a filler rod to melt with the base metal.

The high temperature can also trigger the oxygen and nitrogen in the air. This induces some reactions with the metal, such as oxidizing it and forming a layer of slag on top of the pool. This can weaken the structure of the weld.

As a result, you need to use inert gas to form a protective cloud above the weld pool to prevent it from reacting with the molten metals.

The Other Forms of Welding

There are different disciplines of welding, including Metal Inert Gas arc welding (MIG), Stick welding, and Flux Core welding.

These forms also use the same concept but with different parts. For example, MIG welding uses electrodes made of metals other than Tungsten. Also, flux core welding allows you to weld without using inert gas shielding.

What’s Special About TIG Welding

As you can see, TIG welding is one of the most complete forms of welding. It’s by far the easiest and most precise method of welding. For that reason, it can be a bit pricier than the other.

This also doesn’t mean that it can replace all the other types in all situations. However, having a TIG welder means that you can achieve more while maintaining smooth welds with durable structures.

Is Buying a TIG Welder Worth It?

TIG welders use a Tungsten electrode to heat the base metal. Also, they use inter gas reservoirs to form a protective cloud above the weld pool. This cloud protects the weld from oxidation and reaction with air.

These features make TIG welding one of the best methods if you’re looking for a clean cut. As a result, opting for a TIG welder is a great investment.

Not only do they produce extremely higher quality welds than other methods, but they also do it with an easier process.

If your main line of work depends on the visible weld part, you’ll also benefit from a quality TIG welder. They can work on a very low amperage to weld paper-thin metals with excellent results and noticeable durability.
