When you’re welding thin metal pieces or your welding itself will add to the product’s final looks, then there’s no better way to do the job, than with a TIG welder.

Using a TIG welder offers you precise heat control and other features that you won’t get in a MIG welder. It’s also a more engaging experience because you’ll use both hands and a foot to TIG weld.

To make things easier for you, this TIG welders review looks at the top offers in the market and then shows you how to make the proper considerations when making your choice.

What to Check Before Buying Best TIG Welder?

How to Buy the Best TIG Welder

The following paragraphs shed some light on the different and important parts of a TIG welder. By going through them, you’ll be in a better place to make a perfect choice.

1. Input Power

You’ll find TIG welders that either run on 230 Volts or 115 Volts, so you need to make sure you’re getting the right welder. This voltage is then stepped down to about 30 Volts using a transformer or an inverter.

Most of the modern TIG welders use an inverter anyway and this has many advantages, such as a lighter weight, easily creating high-frequency pulses, and better controls.

2. Duty Cycle

Every machine has its limitations, and this also goes for TIG welders. Given the enormous amounts of power used in TIG welding, the duty cycle is a feature to prevent the welder from getting too hot and damaging its components.

The duty cycle tells you for how many minutes you can use the welder at its maximum output in ten minutes before it will need some rest. It’s given in a percentage of the 10 minutes, such as 40% at 150 Amps, which means four minutes of use at 150 Amps before needing a rest to cool off.

3. Pulses & Pulsed Welding

The major advantage of TIG welders lies in the ability to control many aspects of the welding process, and this is where electric pulses and pulsed welding come in.

Pulsing makes it easy to focus the arc and to only deliver the needed amount of heat. Modern TIG welders produce up to 5,000 pulses per second. Pulsed welding is good for tough joints and thin materials, so you don’t burn through them.

4. Pedal

The pedal separates TIG welders from the rest. It’s used to fine-tune how much heat you are delivering to the welding process. Since the two hands are usually occupied when TIG welding, you’re usually left with the foot to control heat levels.

A good pedal is very responsive and shouldn’t have a too steep surface. You can buy a top of the line pedal for your welder if you don’t like the one it came with.

5. Digital Control & Display

This one is a personal choice. You can either go for a TIG welder with digital controls and display, or you can go for one with analog controls. It’s left for you here to find what best suits you since they both offer equally good controls.

6. Materials

You should know the materials you intend to work with and their thicknesses. This is so you can get the right TIG welder with the right amperage range.

If you’re welding very thin materials for instance, then you can keep an eye out for a welder with an amperage range as low as 5 or 10 Amps. If you’re welding 1/8-inch Aluminum, for instance, then you’ll need a welder with at least 200 Amps of top power.

7. AC & DC Power

TIG welders have two types of outputs: AC and DC outputs. AC stands for alternating current and is the same type that you get from your household electrical outlet. DC stands for direct current and is the same electricity that you’ll get from a battery or electronic device.

You should know this because Aluminum and Magnesium, which are both self-oxidizing soft metals are better welded using AC, while hard metals, such as steel and stainless steel are better with DC welds.

8. Portability

This is another personal issue and is, therefore, left for you to decide. Whether or not you need a portable TIG welder depends on your needs. So you need to ask yourself if the welder will only sit in the shop or if you must take it to work on a site from time to time.

9. Warranty

TIG welder warranties mostly range from 1 to 3 years, with some companies offering longer warranties. With warranties, longer is better, but keep in mind that longer warranties also attract higher prices. So, you have to find your balance between quality, warranty, and price.
