The 10 Best TIG Welder’s

Tungsten Inert Gas welding refers to use of non-consumable tungsten electrode for delivery of current to the welding arc. The challenging factor about this type of welding is engagement. It requires you to use both hands while operating. However, it is worth the effort because the results are excellent- exceptional and attractive welds. In most cases, argon is used in the cooling system. Helium was used in the early years earning the welding process the title heli-arc welding.

For the best TIG welder on the market for your home or commercial use, it is essential to understand the fundamentals of the industry. You will require a TIG welder for your business, car or simple home repairs. The purpose of the welder determines the factors you will put into consideration before buying one. You may wish to also invest in a bench vise for your welding needs!

TIG Welder Buying Guide

What to Look For When Buying a Tig welder

Welding equipment machines are high power consumers. Whether you are an amateur or guru in the field, you need something that will serve your purpose excellently. In most cases, buyers only consider the factors they understand. You will encounter a customer comparing prices without any consideration of the power output and its ability to handle the purpose. For those who are impressed by appearance, the color or design of the welder may play a critical role in purchase decisions.

tig-welder-helmet

I hope this approach would work for you but it rarely does. The above factors barely play a role in landing you the suitable welder. You should understand the factors that will aid you to make an informed and right decision as you buy your tungsten welder. The following factors should help you as you weigh your options.

Input power

The input power determines the kind of tasks that your device can perform. For heavy duties, you need a welder that has a high input power. Most TIG Welding equipment machines have an automatic AC and DC adjustability. However, they will not exceed their maximum power input. The tungsten welder will operate within a particular range. You should know the power phases that your welder can work in without any mishaps. When choosing the input power, you should consider the type of material you will operate on.

Steel and aluminum are the most common types of material. They also come in different material thickness and gauges. If you want value for your bucks (which I am sure you do), you should consider high input devices for thick and dense metals. Direct currents are suitable for hard materials like stainless steel.

tig-welder-man

There are other metals like magnesium which have a low density. Low input power TIG welders are suitable for operating on such materials. An alternative current (AC) will work for you if your material is less dense. Racing cars are mostly made of steel which necessitates the need for a high input if you are a racer.

Duty cycle

This refers to the ability of the welder to operate continuously. It is usually expressed as a percentage or ratio of the total active time (conventional 10 minutes for welding equipment machines). For commercial use or dense metal operations, you should consider machines with a high DC. This will help prevent time wastage as you wait for the welder to cool down.

The cooling system is the primary determinant of a tungsten welder duty cycle. For light tasks like home use, you can prefer low duty cycle TIG welders. It should serve the purpose without any hitches. A power surge decreases the DC because the power input increases the rate of heating overworking the cooling system.

Cheap models have a DC of 20%. The aspect makes them suitable for light tasks and soft metals. High quality and relatively expensive welding equipment machines are design to operate for more than 6 minutes in a cycle- 60% duty cycle.

Weight and size

Most buyers will look for light machines. This factor is crucial because it determines the portability of your device. If your welder operates from a fixed position, you can consider the option of a heavyweight tungsten welder. However, if you are a nomadic worker, buy a machine that you can easily lift from one place to another. The best for such operations should be less than 100lbs.

The size of the transformer, which is the heaviest part of a welder, determines the weight and size of your device. However, some welders are light but difficult to carry because they have unreliable handles which could break while lifting. Ensure the handle is sturdy enough to support the weight of the machine.

Digital display and automation

As said earlier, TIG welders are engaging machines. Automation and digitization make your work easier through features like automatic high-temperature shutdown and balance. These elements are essential for the maintenance of your welder. However, if you are a keen and experienced worker, you will not have a difficult time using manual welders.

tig-welder-sparks

Amateurs are best suited by highly digitalized and automated machines to reduce the tasks that keep their body engaged. Digital display helps you to follow manufacturer’s regulation in terms of voltage, power output, and preferred material.

The accuracy of operation is also improved by use of preset features for voltage and amperage. Considering the factors listed above let’s look at some of the best TIG welders for various tasks.

FAQs

Q. Can I use my welder for aluminum welds?
A. Aluminum requires an alternative current because of its sensitivity. Therefore, if you are working on aluminum material, you should ensure your welder supports an AC.

Q. How do I use my TIG welder?
A. The use of a TIG welder differs depending on the amperage, voltage, and type of material. Some welders will automatically detect the voltage phase in use and adjust accordingly. The amperage is set depending on the DC you want to achieve. If you’re going to work continuously on light metals, your welder will do that perfect at low amperage.

Most packages will come with a users’ manual that elaborates how you should connect and use your machine. You should also consider your level of expertise when purchasing a welder because some may be complicated to use.

Q. Does my welder offer stick and TIG welding options? How do I adjust?
A. Most TIG welders offer you the choice of TIG and stick. Some may not provide the full package although they are compatible. You only need to buy the stick to enhance this option.

Q. What does duty cycle mean and how does this affect my welding?
A. The term refers to the percentage of time your quality weld can work within 10 minutes. The rate is always given in ratios or percentage. DC determines your total output when working continuously.

Expert’s tip

Hydrogen is one of the worst elements when welding. Because it is readily available in the atmosphere, you should keep your welder clean to avoid inhibition by the component. The element will cause cracking of welds hours after finishing your work. Read more about the TIG welding process in this educational study here.

Did you know?

The earliest welds in history are dated back to the Bronze Age- 3,500 B.C. The arts were discovered in ancient Egyptian tombs.
