Hobart 500551 EZ-TIG 165i AC/DC TIG WelderNeed a serious tool for metal work?

In this write-up, we have put together a series of vital info on welding procedures, TIG welding, and presented unbiased reviews of top TIG welders. Reading through our best TIG welder reviews would help you to pick the right machine without much fuss.

When we carried out a study, we found that at present the market is filled with different models of TIG welders. These units vary in their prices, features, and usability. So, to make the process of picking the right TIG welder easier for you, we have reviewed the best units available on the market currently.

What is TIG Welder?

The term “welding” is used for a sculptural or fabrication process used to join materials, particularly thermoplastics and metals. The procedure causes fusion (it’s a different kind of fusion compared to what we see in lower temperature material joining techniques such as soldering and brazing) and thereby joins two different metal surfaces aptly.

A TIG welder is also often referred to as Gas Tungsten Arc Welder. These machines work by fusing the metal parts to be joined together by means of heat produced from an electric arc. The said electric arc gets established in between the work-piece and a non-consumable (something that wouldn’t melt) tungsten alloy electrode.

The weld pool temperature can become as high as 4530  F or 2500 C during TIG welding. The inert gas (the gas used for this purpose may be helium or argon or a blend of both) used during the procedure plays a vital role in sustaining the arc and ensuring that the molten metal doesn’t get contaminated by the atmospheric elements.

The process first came into being during the final years of the 1930s, a time when the need of welding magnesium suddenly became apparent.

You can use a TIG welder in all possible welding positions. Underwater welding is also possible. That’s not all; these machines can be used in automatic, semiautomatic, as well as manual modes. What modes you will be able to use depends on the equipment you are using and the kind of job you are using it for.

How To Choose TIG Welder- Buyer’s Guide

Are you looking to buy a perfect TIG welder and don’t know where to start?

If yes, then considering the following points is a must for ensuring that you are buying the right product.

  • Amperage range

Ideally, you should look for a piece that is offering the maximum amperage range for a reasonable price (a price that matches your budget). The wider would be the range, the greater would be your welder’s flexibility. For instance, if the amperage of a machine ranges between 5 A and 230 A, it would be able to weld thin materials such as stainless steel and thick materials like aluminum with equal perfection and ease.

  • AC/DC welding


Individuals, who have plans of using the welder for other materials besides stainless steel or steel, must buy a welder that offers both DC and AC options. Having the DC option is a must for welding hard materials like steel, stainless steel, and deoxidized copper. However, for welding aluminum, magnesium, and other soft, self-oxidizing metals, having a welder with AC option is a must.

  • Duty cycle

The duty cycle of a welder shows how much welding it can complete uninterruptedly during a 10-minute interval. The specification is represented by a percentage value. On average, the TIG welders of highest grade has low, medium, and high duty cycle respectively of 20%, 60%, and 80%.

  • Heat control

For getting precise results when welding thin metals, you must ensure that the welder you are using has the right heat control.

  • Price

As expected, pricey products marketed by reputable manufacturers almost always turn out to be extremely efficient. However, with a little research, you will also come across inexpensive units showcasing amazing welding performance.

Types of Welding

  • MIG welding

MIG or Metal Inert Gas welding, which happens to be the most widely used industrial welding procedure, is primarily used for fusing stainless steel, aluminum, and mild steel. It involves joining two metal surfaces using a wire which remains connected to electrode current.

MIG welders use a shielded gas together with that wire; the gas performs the job of heating up the metal surfaces to be connected. The other two essentials for this welding procedure are a direct current power source and constant voltage.

  • SMAW or stick welding

SMAW or Shielded Metal Arc welding, which is also often called Stick, is the most fundamental welding procedure. The stick works by using electric current for producing an electric arc connecting the metals to be joined and the stick. SMAW welding is primarily used for welding steel and iron and finds uses in repair as well as construction work.

  • FCAW

FCAW or Flux-Cored Arc welding was originally designed as a substitute for SMAW. It has significant similarities with MIG welding. However, there’s also a strong exception. Unlike MIG welding, FCAW uses a specially designed tubular wire carrying flux and doesn’t always need a shielding gas.

The other factors that make FCAW the favorite procedure of many construction workers are its cost-effectiveness and comprehensibility. However, it also has a number of limitations. The most prominent one among them is surely its inability to offer aesthetically pleasing results.

Still, FCAW is frequently used for completing construction projects because of its remarkably convenient portability and impressive welding speed for sheet metal or exhaust.

  • TIG welding

TIG or Tungsten Inert Gas welding involves the use of non-consumable tungsten electrodes for producing the weld. You will know more about the process as you will read the rest of the article.

Material Types a TIG Welder Can Join

You can use your TIG welder for welding almost every metal alloy and metal that is currently in use. However, these machines have turned out to be most cost-effective when used for welding low gauge metals i.e. metals that have a thickness below 3 mm.

What’s more amazing is that TIG welding often appears to be the most useful procedure when it comes to welding metals that are extremely tough to weld using other conventional welding procedures. Examples of such metals include the following:

  • Nickel, nickel alloys
  • Copper, copper alloys
  • Magnesium, magnesium alloys
  • Aluminum, aluminum alloys
  • Reactive materials such as tantalum and titanium
  • Carbon steels, low alloy steels

Additionally, it often turns out to be the only suitable option for joining alloy steels and carbon. But wait, there’s more in store; due to its ability to work with the most difficult metals, use of TIG welders is pretty common in aerospace industry and automotive industry. These devices also find use in metal furniture manufacturing. Invertec® v160-t tig welder is a good tool to work with.

TIG Welder vs. Arc Welder

Tig welders (also known as gas tungsten arc welders) use non-consumable tungsten electrode for producing the weld in order to carry out arc welding.

The devices used for carrying out gas metal arc welding or shielded metal arc welding don’t use a non-consumable element. The TIG welders also provide the operators with much greater control over the job than individuals using other arc welders.

TIG Welder vs. Stick Welder

The primary difference between a TIG welder and a stick welder is that the former is a lot more versatile than the latter. TIG welders can be used for welding almost all kinds of metals, while stick welders are suitable primarily for welding works involving steel and cast iron.

The other prominent difference between stick and TIG welders is that unlike the former, TIG welders are capable of completing the welding job cleanly. Stick welders often end up causing serious spatter and slag.

TIG Welder Common Problems – Troubleshooting Guide

Although each of the Tig welder models we have reviewed earlier in this write-up is highly user-friendly, the basic process of TIG welding is arguably extremely difficult to learn. This makes it important for you to know the problems you may face. The section below would help you get acquainted with some of the most common TIG welder problems.

Poor gas coverage might cause contamination

If the shielding gas of the machine is not activated, weld contamination may occur. The other situations that might lead to weld contamination include excess or insufficient shielding. You might also experience contamination if the gas gets blown away. For troubleshooting this problem you will have to do the following:

  • Check the label of your gas cylinder to ensure that you are using a gas suitable for TIG welding (100% argon or a blend of argon and helium for aluminum)
  • Make sure that the gas flow rate is proper (ideally between 15 and 20 cfh)
  • Avoid using the regular collet body; instead, use a gas lens for enjoying more efficient gas shielding
  • Inspect all hoses and fittings to spot leaks (use a leak detection fluid for completing the inspection flawlessly)

Weld graininess

This occurs mostly when the welding temperature becomes too high and the base metal gets excessively diluted. Here are a few things you can do for preventing the problem:

  • Try to find the temperature that is neither too cold nor too hot, for the materials you are welding; this will prevent the formation of grains on the welded surfaces.
  • Check whether you are using the right filler material
  • Don’t forget to remove all moisture, oil, and grease from the base and filler metal

Crater formation

Craters are often formed during the final stages of the weld. The biggest disadvantage of having craters on the welded metals is that they often cause cracking of the structures.

Common causes of crater formation include quick removal of filler rod and sudden drop in weld power. The problem can be avoided successfully by being a little careful or by using TIG welders equipped with a crater-control feature.

Oxidation or sugaring

Stainless steel often becomes a victim of oxidation or sugaring when the welded parts come in contact with oxygen present in the atmosphere. Having sufficient gas coverage at the back and front of the weld would help in avoiding this problem.

How to Use

You will have to begin by picking the right electrode. You will most likely have the right kind of electrode embedded in your TIG welder. For welding aluminum without undercuts, you would need a rod made of 100% pure tungsten. Alternatively, you can also pick a tungsten alloy (even the radioactive alloy thoriated tungsten will be a good choice); these alloys turn out to be useful particularly when welding metal alloys.

Next, you will have to grind the device’s tungsten rod to a certain point. You will need to grind particularly when the tungsten rod would have a perfect cylindrical shape (new rods are mostly perfect cylinders) instead of the desired rounded or pointed tip. Here, it must be noted that experts believe that for AC welding, the rod must have a rounded tip and for DC welding, it must have a pointed tip.

That’s it; you are now ready to use the device; here are the steps you’ll have to follow:

Step 1: Insert the device’s electrode into the device’s collect

Step 2: Choose the suitable settings

Step 3: Turn the gas on

Step 4: Get the welding table and metal ready

Step 5: Wear the right welding gear

Step 6: Check whether you can move the device freely

Step 7: Start welding

Here is the list of the top welder manufacturers: Lincoln, Lotos, Miller, Everlast.

Safety Tips

  • Before beginning to weld, make sure that you have set up the device correctly for current, voltage, gas flow and shielding rate, and material.
  • Make sure that people working around you are protected from IR and UV radiation flash. For that, you will have to either place a UV screen between the people around you and the working area or drop down the UV curtain.
  • Make sure the is an oxygen flow working in the tight areas.
  • The workplace doesn’t have any oxide or paint. This is essential for ensuring satisfactory electrical contact.
  • Keep your eyes and skin duly protected for avoiding damage from accidental welding flashes. Keep checking the device’s welding torch assembly from time to time.
  • When the job is complete or if the job gets interrupted, turn the shielding gas and machine off. Also, store the hand-piece in a safe place.

Care and Maintenance

Never use the welder beyond its capacity. The device’s duty cycle would help you to understand its limit. This makes it crucial that you pick projects carefully and keep track of the device’s performance.

It’s important that you clean the TIG welder on a regular basis. Accumulation of debris and dust might end up covering the machine’s mechanical parts and thereby stop it from delivering optimum performance. Cleaning these welders is easy. You will also need to remove its cover and blow the machine with compressed air. At times, you might also need to apply lubricants in certain parts of the machine.

After a few years of use, it would be wise if you get your TIG welder checked by an experienced and qualified technician. He or she will remove grime, dirt, and dust from the unit’s cooling fans, PC boards, and transformers and help in prolonging the machine’s service life.

Weight and Portability

It’s important that the TIG welder you buy is not too heavy. This would allow you to take it to various job sites whenever you want. Ideally, the weight of these machines should range between 30 and 60 pounds.


It would be good to get a device that comes with a manufacturer’s warranty of three or five years. If that’s not possible, make sure that the welder you are buying has manufacturer’s warranty of at least one year.


Is there any color used for marking tungsten electrode?

Yes, pure tungsten electrodes are usually marked by the color green. Alloys also have their own color markings. For instance, thoriated tungsten electrodes are marked by the color red.

What are the causes of formation of yellow smoke or powder on the tungsten electrode?

This mainly occurs when the quantity of shielding gas is not enough and the tungsten starts reacting with the atmosphere.

However, for making the most of these welders, you would need to buy a high-quality product and put in a significant effort for learning the dos and don’ts of TIG welding. The best TIG welder reviews presented by us should help you immensely.

We recommend TIG200 Aluminum Welder by Lotos as it’s an ideal unit for beginners and weekend enthusiasts looking for a feature-filled, but affordable welder. At the same time, professionals in search of an industrial-quality, robust welder would also find it extremely handy. To put it more bluntly, it’s a perfect piece of any individuals in need of a welder for joining stainless steel, mild steel, aluminum, and various other metal types.

We recommend this TIG welder as it scores impressively in departments like flexibility, usability, reliability, versatility, and affordability. You will struggle to find a similar tool priced as reasonably as this one.
