Buyer’s Guide: The Best Tig Welder

Hobart 500551
Tig Welder

For those that are amateurs and are just dabbling into welding, tig welding stands for “tungsten inert gas.” Although, the term technically has the word “gas” in it, the acronym GTAW isn’t nearly as catchy as the aforementioned. So what exactly is tig welding you may ask? The process of tig welding is when there’s a non-consumable electrode that delivers electricity to the arc that you’re working with. Typically, this process to the arc is protected by a type of argon, and the metal and tungsten are typically protected by the inert gas we spoke of. Whether you already have a tig welding setup or you’re looking to buy one for the first time, we think you should continue reading. In this article, we’ll discuss the benefits of using a tig welder, factors to consider before purchasing a tig welder, as well as tips to know before taking the plunge and buying a piece for tig welding.

Benefits of Buying a Tig Welder

Before we get heavy into factors and information you should consider before purchasing, let’s do a quick rundown of the benefits that a tig welder offers.

Does more than metal – There are many welding processes that are able to use alloy and metal, sure, but tig welding is known for being able to use the most types of metals and alloys, including magnesium, copper, gold, brass, stainless steel, and many more.

Versatile applications – Tig welding isn’t only used for industrial or professional purposes, as you can also create art with the welding of metal! Those that are looking at this article for art buying purposes can find useful information in our next section.

Clean welding – Because of the superior puddle control that a tig welder offers, you’re going to be able to create clean welds. Other benefits include:

  • No sparking, or splattering like other welding forms
  • No slagging or flux
  • No fumes or any type of smoke

Various positions – You can even weld in various angles or positions like vertical, flat, overhead, of horizontal! Whether you’re in a confined space or you’re working on something that’s an awkward angle or shape, you can do so with ease as you use a tig welder.

Factors to Consider Before Purchasing a Tig Welder

When purchasing a tig welder, you’ll want to know the basics of tig welding (beyond the definition) and practice first with a basic machine. When you’re ready to buy, you’ll want to know more about selecting the best tig welder. First things first: power. Without the proper power, you won’t be able to complete your application with ease. The types of power inputs include the forthcoming:

Amperage range – We understand the constructs of your budget, but it’s imperative that you choose a machine that offers an incredibly wide range of amperage for the best price – this is why we encourage researching more to define what’s the best range for your budget. Typically, the best range of amperage for a tig welding machine is between 5 and 230 amps, giving you a ton of flexibility, even if you’re using an extremely thin material. Speaking of the aforementioned, the thickness of the materials used will definitely cause you to purchase a specific tig welding device in the end. Basically, the better your amperage range, the more versatility you’ll see in completing various projects or applications.

AC/DC Welding – No, you aren’t going to be looking into booking one of your favorite 80’s bands, although we’re almost positive that this is where they get their name from. For welding, you should always seek a device that’s able to switch between AC/DC for the optimum versatility between applications. The AC mode is used for softer metals that are considered self-oxidizing, while DC is used for deoxidized metals (- these are considered hard metals).

  • Soft metals include: magnesium, aluminum.
  • Hard metals include: Steel, Stainless steel, copper.

Low amperage – Yes, low amperage is a thing! Those that want arc stability should look for something that has a lower amperage. Even though the above mentioned amperage range says that you should go with a wide range, having a lower amperage is talking about the machine that is supplying power to the tig. The device itself needs a lower amperage, while the tig welder needs a wide range.

You should also know about something called a duty cycle, which is imperative to know as you’re searching and working on projects. Typically, a duty cycle is the intervals of ten minutes in which you can perform uninterrupted welding. The aforementioned cycle is when the device can go up to its peak current. When it does this, you should leave it to cool afterwards or after a short period of time. Overusing when the machine gets too hot can not only result in a broken machine, but harm done to the welder.

Don’t think duty cycle is as easy a reading a meter though; seasoned veterans know this – duty cycle requires a bit of manual mental math, as the readings are typically done in a percentage mode. In order to get the proper reading, you must multiple the percentage shown on the machine because of the interval. When you don’t multiple during the peak current, you run the risk of frying the machine entirely. In short, cheaper models that aren’t of quality will only show you 10% of continuous welding before it becomes too hot to use. The aforementioned math is done because of the cheaper machines only seeing one full minute at the peak current before it starts to do down south; unfortunately, not optimal for those who tig weld often or professionally.

Devices that are typically introductory, but are industrial see between a low of 20% and a high of 80%. Although, it’s not uncommon to see a medium of 60%. While there are some ways to get around this, such as the manufacturer tweaking the product, they’re able to use a lower amperage on the device in order to get more uninterrupted welding out of the machine. If you’re still unsure of what this means, a device that’s working at 140 amps could run at 30% out of the 10-minute interval if it’s running on 115 amps. Beyond able to know this and choose a device that’s versatile and inexpensive is key in getting the most bang out of your buck.

Tips to Know Before Purchasing a Tig Welder

Before you purchase a tig welder, you should define your budget, and make sure to research budget ranges. When you don’t know what you’re getting for a certain price, you may think you paid a good price, but you might be overpaying or not seeking the full potential of your budget. Beyond this, you’ll need to check out other devices and even accessories to make sure that you’re going to be able to use them. Of course, you should never start using a tig welder unless you’re familiar with the controls. Setting the wrong temperature for the project you’re working on isn’t as innocent as you may think, because you could ruin the machine. You could also ruin the project you’re working on, as you’re not stabilizing the weld with the proper temperature that’s required. Don’t risk losing a client because you didn’t want to do a bit of research on the controls of the best tig welder!
