Welding takes precision, patience and incredible skills, but you can’t get any of it done without the right tools. Whether you're working in a shop, out on the field, or in your garage, a dependable welding torch is essential for getting the job done right. But with so many welding torches to choose from, how are you supposed to know which one to choose? Don’t worry, it’s not just you. Many welders have trouble figuring out exactly which welding torch or welding torches work for their specific needs or applications. In this guide, we’ll explain each welding torch and help you find the perfect one for your next project.

What is a Welding Torch?

If you’re wondering which welding torch you need, chances are you know what a welding torch is. But, here at Arc-Zone, we never like to assume.

A welding torch, whether used for TIG, Oxy-Fuel, or Plasma Arc welding, is a handheld tool that controls the flow of gas, electricity, or both to produce the heat needed for welding. Depending on the type of welding torch you use, the heat source can vary from an electric arc to a controlled gas flame. This function remains the same for every welding torch, but did you know that there are variations of welding torches designed to meet many specific needs?

These variations cater to different materials, welding environments, and levels of precision. For example, in TIG welding, you will see two and three series torches. In Oxy-Fuel welding, the choice between Airco and Victor style welding torches can influence everything from cutting speed to fuel efficiency. Similarly, in Plasma Arc welding, you have the option between high-frequency and contact-starting welding torches, depending on whether you need to prioritize speed or precision. The options are virtually endless, allowing you to choose the exact welding torch that best suits your project’s demands.

Which Welding Torch Do You Need and Why?

Like we said earlier, the hardest part is figuring out exactly which of these welding torches you need for your specific application. You can’t just use any old welding torch for precision welding and you sure can’t use a TIG torch if you’re out in the field with no electricity. In this section, we’ll break down the different types of welding torches—TIG, Oxy-Fuel, and Plasma—so you can find the perfect match for your next project.

TIG Welding Torches

If you’re looking for a welding torch that gives you clean, precise welds, a TIG welding torch is the way to go. TIG welding, also known as Gas Tungsten Arc Welding (GTAW), is useful when working with thin metals or when appearance is a top priority. The precision of a TIG welding torch creates clean, high-quality welds that require minimal cleanup.

Why Choose a TIG Welding Torch?

• Precision: Because TIG welding allows for better control over the heat and overall welding process, a TIG welding torch is ideal for detailed work.
• Versatility: TIG welding torches have the capability to weld on a variety of metals, including aluminum, stainless steel, and copper.
• Clean Welds: Thanks to the minimal spatter produced by TIG welding, welds come out much cleaner and require less grinding or finishing.

TIG welding torches, while they produce some of the most beautiful beads you’ll ever see, require more practice than other welding torches. Unlike Plasma Arc and Oxy-Fuel welding torches, TIG welding torches involve two hands—one to hold the torch and one to feed the filler material. But don’t let that stop you from trying. TIG welders are the most in-demand welders, especially for the aerospace, food processing, energy, and medical industries.

Oxy-Fuel Welding Torches

Do you weld out in the field? Do you have minimal power sources on the job site? An Oxy-Fuel welding torch is just what you need! Oxy-Fuel welding torches, while they do require a mixture of oxygen and fuel to create their flame, they don’t require electricity. Wild, right?! Maybe it’s just us, but the fact that a welding torch works without electricity blows our minds. This technology was introduced in 1903 but it makes us say, “wow” just as much as today’s robotic welding does.

Why Choose an Oxy-Fuel Welding Torch?

• Portability: Because Oxy-Fuel welding torches don’t require electricity, they’re the perfect welding torch for remote job sites or when power is limited.
• Versatility: Oxy-Fuel welding torches also have the ability to cut, heat and bend metal.
• Power: The flame from an Oxy-Fuel welding torch can reach temperatures of over 6,000°F which makes it easy to work with thick metals and heavy-duty jobs.

Oxy-Fuel welding torches are the perfect choice for welding jobs that don’t require the precision of TIG welding; however, you still must be precise with gas mixtures and careful with the handling of gas cylinders. Be sure to have proper ventilation during the combustion process.

Plasma Arc Welding Torches

Are you looking to achieve stronger welds at faster speeds?

According to the welding experts at Fronius, “Plasma welding is similar to TIG welding. The difference is that in plasma welding, the arc is sharply constricted by a cooled gas nozzle through which a flow of plasma gas is directed… The concentrated arc results in maximum energy focus, leading to a deep penetration effect in the workpiece that can only be matched by a laser beam. What is more, the welding speed is as much as 20% faster than in mechanised TIG welding.”

Why Choose a Plasma Arc Welding Torch?

• Speed: Plasma Arc welding is “20% faster” than TIG welding. If you need to complete a project with minimal time, a Plasma Arc welding torch is the way to go.
• Cost-Effective: Plasma Arc welding torches use less filler material and produce minimal waste.
• Precision: “The shielding gas flows through the outside gas nozzle, providing an optimum gas shield to the weld seam,” which means, “no porosity, a perfect weld-seam appearance and zero spatter.”

The only downside to Plasma Arc welding torches is all of the equipment required is a bit bulky. Plasma Arc welding torches are better suited for shop use rather than fieldwork.

Choosing the Right Welding Torch for Your Metal Fab Project

Now that you have the basics of each welding torch, it’s time to determine which of these welding torches is the perfect fit for your metal fabrication project.

Factors to Consider When Choosing the Right Welding Torch

• Material: If you’re working with thin or non-ferrous metals, TIG welding torches are a great option. For thicker materials, we recommend using an Oxy-Fuel welding torch.
• Environment: When welding where power is limited, Oxy-Fuel welding torches are the best choice as they don’t require electricity. If you’re working in a production shop, Plasma Arc welding torches can help speed up your welding process.
• Skill Level: This depends on how experienced you are. TIG welding requires more skill and practice, while Oxy-Fuel and Plasma welding torches can be easier to learn.
• Speed: If you need to complete a fabrication job in a timely manner, Plasma Arc welding torches offer the fastest welding process.

We would like to point out that, while we know we’re talking about finding you a welding torch here and now, it’s important to know where welding torches came from and why certain welding torches are used for specific applications. Like we said, you can’t just use any welding torch for whatever metal fabrication project you’re working on. So, let’s get into the specifics to really get a grasp of which of the welding torches you need.

TIG Welding Torches

Back in the 1930s and 1940s, when the aerospace industry was booming, there was a growing need for a welding method that could produce clean, high-quality welds on light and thin materials like aluminum and magnesium. Traditional welding techniques were inadequate for the task, often leading to weak joints and defects.

Russell Meredith, a welder and engineer working for Northrop Aircraft, discovered that using a tungsten electrode and an inert gas (typically argon or helium) to shield the weld area from atmospheric contamination could produce precise and clean welds.

TIG welding torches are used mostly in the aerospace industry, where the need for high-strength, lightweight materials are paramount. TIG welding allows for the joining of reactive metals like aluminum, magnesium, and titanium without the risk of oxidation or contamination. Because of their ability to produce precise, clean welds, TIG welding torches are the first choice for industries, like medical and food processing, where contamination control is pertinent.

Oxy-Fuel Welding Torches

Did you know that Oxy-Fuel welding torches played a huge role in World War I and World War II? Because of their portability, Oxy-Fuel welding torches were invaluable in field repairs and on-site construction projects, and crucial in the rapid construction of military vehicles, ships, and infrastructure.

Today, Oxy-Fuel welding torches are popular among shipbuilders and pipeliners. Oxy-Fuel welding torches are also used in applications such as metal cutting, brazing, and welding in industries ranging from automotive repair to sculpture.

Plasma Arc Welding Torches

In 1957, Robert Gage, an American scientist working at Union Carbide, introduced Plasma Arc welding. Gage’s goal was to improve arc stability and control in the TIG welding process; however, he ended up creating an entirely new process with a plasma jet that could cut through metal with unprecedented precision.

Plasma Arc welding was, and still is, the go-to application for industries such as electronics, aerospace, and medical device manufacturing. If you’re welding thin sheets of metal and require minimal distortion or warping, a Plasma Arc welding torch is your best option. Plasma Arc welding torches also use less filler material, making it a more efficient and cost-effective option for high-production environments.

Keeping Your Welding Torch in Tip Top Shape

Now that you have an idea on which welding torch you need, it’s important to maintain it properly. Regular maintenance ensures your welding torch will perform well and last for years.

Maintenance Tips for Welding Torches

• Keep It Clean: Avoid performance issues and prevent debris buildup by regularly cleaning the torch and its components.
• Check Connections: Inspect the hoses, cables, and connections for wear or damage, and replace them as needed.
• Use the Right Consumables: Make sure you're using the correct nozzles, tips, and filler materials for your specific welding torch.
• Store Properly: Store your welding torch in a cool, dry place when not in use to prevent rust and corrosion.
