Getting The Best TIG Welder Options On the Market In 2021

Whether participating for a personal hobby or for expert heavy industrial use, welding is considered to be a highly advanced process in the world of fabrication. It becomes much less complicated through knowledge and experience but choosing what machine to invest in can feel intimidating for welders of any experience level.

Identifying your needs and comparing against the available options is the first step in the buying process. Discussed here are the factors to consider when looking for a new welding machine along with our top recommendations to ensure you have the information needed to choose the best TIG welder for your specific welding requirements.

Why TIG Welding Matters

There is an array of available welding processes and techniques which are suitable for different purposes and industries. TIG, or Tungsten Inert Gas welding is an extremely versatile method of arc welding. It is used for joining most metals such as aluminum, titanium, copper, magnesium and steel.

Although TIG welding can take longer and may require slightly more energy than other available welding techniques, it remains one of the most common. It is often preferred for its diversity in ability, stability and strength, production of high quality welds with nearly no smoke or residue, and a very low occurrence of defects. It can be used with or without filler wire in all welding positions and the process can even be automated.

Considerations When on the search for the Best TIG Welder

TIG welding machines can provide control over all the aspects of your weld such as filler speed and amperage. There are several high-performing TIG machines that will produce reliable welds but there are a variety of features, settings, and sizes they may offer. That means there are many considerations to keep in mind when looking to purchase a new TIG welder.

Type of Metal

TIG Welding is appropriate for joining a large variety of metals but different machines have different capabilities so knowing what you will be working with may affect your purchase decision. TIG friendly metals include brass, copper, gold, steel, aluminum, magnesium, stainless steel, and bronze.

Metal Thickness

TIG welding can handle a range of thicknesses, but when comparing against other welding methods it is especially preferred for the thinner metals as it can maintain stability and precision at low amperage operation.

Required Power Source

It is common for TIG machines to have both alternating current (AC) or direct current (DC), but not all do. They type of metal you use will determine which current you set to so if you are not sure or just want the option of variety, you may want to consider purchasing a dual current machine.

Features to Compare When Shopping for the Best TIG Welder

There are several components to a TIG welding machine and depending on your purpose for welding, certain features may be more important to you than others. Here are some main aspects to compare amongst potential purchases.

Portability

Welding machines can range from under 30lbs to over 100lbs making some much easier to move around your shop than others. Smaller size does not necessarily equate to less capabilities as many lightweight designs, while keep portability in mind, still provide you with great versatility and high power.

Foot Pedal

You will likely want to have a reliable foot pedal as controlling amperage is a critical component to welding. An ideal foot pedal will have a low-angle slope to avoid foot fatigue and be sensitive to your adjustments of heat input. You want to remain comfortable as possible while your equipment remains reliable over long periods of extensive use.

Simple Controls

The convenience of adjusting controls is as important as their reliability and how secure they are on the machine. You want to easily make adjustments without it being too easy to accidentally bump into the machine and accidentally switch settings. Choosing the proper control setup is a personal preference but still important to keep in mind for your unique welding situation.

Pulse Capabilities

Avoid problems with the structure and look of your weld by insuring you have a high-quality and steady arc. Pulsing capabilities assist in controlling the amount of heat applied to the metal and are needed for difficult joints or with thinner metal. Models that do not cater to such stability can affect quality and visual integrity of your weld.

Versatility Multi-Function Options

Many TIG Welders offer the ability to switch between multiple welding types. Choosing a model with plasma cutting, MIG or stick welding options enhances the proficiency and therefore enhances the value of your machine. If these are not features you will use it may not be worth investing in the extra features, so keep your intentions for potential projects in mind when evaluating TIG welder capabilities.

Common Operating Mistakes with TIG Welding

An awareness of the common issues TIG machine operators often run into may help you analyze your circumstance, enhancing your ability to pick the best welding machine for you.

Too Much Power

Power levels are important, especially when first beginning to practice. You will want to start off using the minimum power until you can sustain your puddle. TIG welding is based on penetration, so you can burn right through if you get too much.

Lack of Cleaning

TIG welding is very reliable, but requires the metal to be clean in order to be effective. Contamination can also lead to poor arc formation. Maintaining a clean work or shop environment will only help as well.

Using Incorrect Tungsten

Different metals are associated with different tungstens, so  you will have to find which one performs best according to your surface metals to join and the work conditions you are in.

Using Improper Grinder

Using an all-purpose grinder instead of a tungsten sharpener or even a bench grinder will contaminate your electrodes.
