Things to Consider Before Buying

Irrespective of your level of skill, you must do more than simply choose the first welding machine you can find. These are sophisticated tools that differ in their design, style of operation, and functions. 

For you to find the best TIG welder for home shop or business, there are essential aspects you need to consider beforehand.

Input Power

One of the most vital factors to consider is the input power of a machine. After all, this is what dictates the kind and array of tasks it can perform. If you often handle heavy-duty projects, you need a unit with higher input power.

A powerful welder can allow adjustments to carry out operations that require a lower power input. However, it will still only handle tasks that can be performed within its maximum power input. You need to ensure that your regular operations are within the power input range of the machine you choose.

To find out whether a specific unit is ideal for you, also consider the type of material you weld. DC power input works perfectly when welding thicker and harder materials such as stainless steel. 

On the other hand, low input AC ensures clean welds when working with lighter and more delicate materials such as aluminum.

It is also necessary to consider the power input you need based on the gauge of the metals you weld. In case you work with thick gauge metals, you again need a TIG welder that has higher input power.

Duty Cycle

The duty cycle of a machine is simply its ability to operate continuously. It is calculated based on the ratio or percentage of time a welder remains active within a 10-minute duration.

If you often handle commercial operations or you work with dense metals, consider choosing a TIG welder that has a higher duty cycle.

Machines with a 60% duty cycle can run nonstop for 6 minutes before they need to cool down. On the other hand, a unit with a 40% duty cycle needs to cool down after running for 4 minutes. A high duty cycle hence reduces time wastage while at the same time increasing your overall productivity.

The cooling system of a TIG welder also dictates its duty cycle. Now, what do I mean by that? Units that are prone to heating up can overwork the cooling system, and this drastically decreases their duty cycle. 

Irrespective of whether you handle heavy or light-duty fabrication projects, always ensure that your welder of choice has a dependable cooling system.

Weight and Size

The weight and overall size of a TIG welder also matters. This is a crucial aspect to consider, especially if you are a mobile fabricator. In that case, choosing a lightweight machine that is ergonomically designed for easy transportation would be ideal.

I run a small welding business and often use my welding machines from a fixed position. In my case, a heavyweight unit with a bigger and heavier transformer is great. Once I unpack the device and get it assembled, I hardly ever need to move it.

Automation

TIG welders are precision tools. They allow better control of the arc, allowing you to create top-quality fabrications. Digitization and automation of welding machines make them more comfortable and safer to operate.

For instance, some units have an automatic high-temperature shutdown feature that makes them turn off when they overheat. This prevents unwarranted damage and helps to extend the lifespan of the Welder.

The digital display shows you the auto-dialed or manually dialed settings. If you are doing precision tasks, it’s easy to ensure you are using the correct power output, voltage, and amperage.

For beginners, the more digitized and automated features a machine can offer, the better. You want to use a tool that automatically adjusts the settings, depending on the material you are welding.

Price and Warranty

TIG welders are not cheap machines. Depending on the input power, duty cycle, features, and functions a device has to offer, it could easily cost between $400-$1000 or more. Take it from me; you only get what you pay for.

A powerful and high-performance unit is likely to cost more than an average light-duty TIG welding machine.

Generally, the more powerful and durable a welder is, the more it will cost. Even though there are affordable units such as the Amico TIG 160 Amp that are incredibly sturdy and reliable, the majority of bottom priced welders are not durable.

While considering cost, take note of the value you will get for your money. Additionally, take into account the ability of a specific machine to meet your primary objectives. Make sure your buying decision is not solely based on price.
