What is Pulse TIG Welding used for?

Pulse TIG welding is a process that is used for welding various metals together. It is a type of TIG welding that uses a pulsing current. This causes the weld to be more stable and results in a higher quality weld.

However, pulse TIG welding is often used for welding thin materials, such as aluminum, because it produces less heat than other welding processes.

I have also discussed what pulse welding is and what pulse tig welding is used for. So if you know about it, the below article will be helpful for you!

What is Pulse Welding?

Pulse welding is a welding process that uses a pulsing current to produce welds. The pulsing current melts the metal and creates a weld. Pulse welding can be used to weld different types of metals together.

What is Pulse Tig Welding used for?

Pulse TIG welding is used to weld metals together. The process uses a TIG welder, and the welding uses a pulsing current. 

This type of welding is often used to weld aluminum because it creates a solid weld. Pulse TIG welding can also weld other metals, including steel and stainless steel.

Pulse tig welding is commonly used in sheet metal fabrication and automotive repair.

When to Use Pulse for TIG Welding?

Pulse can be used when joining two different types of metals together. This helps make the welds more robust and more secure. When you use pulse welding, you use a very high voltage and send a high amperage current of electricity through the wire.

The wire heats up quickly, and the intense heat can weld the metal together. Pulse welding is also known as short circuit welding.

The wire can be cut to any length and size. You can adjust the speed and energy of the pulse. Pulse welding is fast, reliable, and easy to use. You can produce any weld size if it fits in the torch. It produces consistent results but requires practice to master.

Pulse can be helpful when you are trying to achieve a delicate weld bead. The pulsing action creates a more consistent weld bead, which can be beneficial when trying to produce a high-quality weld.

Purpose of Pulse Welding

Welding using a pulse is the easiest method of producing TIG welds. A tungsten electrode is connected to the joined metal, and the current is sent to the wire. 

The current passes through the tungsten, producing a red hot plasma ball. A stream of inert gas carries the plasma to the joint. There it fuses the layers of metal.

The process of creating an inert gas stream is similar to that of standard TIG welding. This is done using the same welding torch but a different tip type. The pulse is sent out to the tungsten electrode utilizing an inverter. 

The inverter also controls the voltage used for the arc. In this case, the voltage is usually 200 V but can also be as high as 600 V. The higher the voltage, the greater the heat produced. This makes the weld stronger.

What Pulse Settings do I use?

Different pulse settings depend on what you want to weld and what material you use. 

In general, you want to use the lowest setting possible. This will create the smallest diameter weld bead. Higher pulses, such as the 40% setting, will create a larger weld bead. 

You can use the 70-80% setting for thinner metal thicknesses, such as 1/16-inch thick, while a lower 40-60% setting works best with thicker materials. 

The 100% setting creates a larger weld bead and can be used for any material. When welding stainless steel with carbon steel, you want to use the 80-100% setting. 

This will produce a fine weld. The 80% setting works well with carbon steel, and you can use the 100% setting for stainless steel.

Advantages of Pulse TIG Welder

Pulse welding has several advantages over regular arc welding. It allows the user to control the welding temperature and time. The heat is so intense that it can melt a large amount of metal. You can also choose how much heat you want and select the correct voltage to produce the desired heat.

It is more popular than ever because of its many advantages. You can use it for various purposes, including combining stainless and carbon steel.


When would you use a pulsed TIG?

Pulsed TIG welding is a variation of the standard TIG welding process. In pulsed TIG welding, the weld current is pulsed on and off, which results in a more stable arc and less spatter. This makes it a good choice for welding thin metals or welding in tight spaces.

What is the advantage of pulsed TIG welding?

Pulsed TIG welding has a number of advantages over traditional TIG welding. It is more efficient because it uses less energy and produces less heat. It is also more precise because the pulses create a stable arc. This results in a cleaner weld with less distortion.

Can you weld aluminum with Pulse TIG?

Yes, you can weld aluminum with Pulse TIG. The process is very similar to welding steel, and it produces a strong, clean weld. However, you do need to use a different setting on your welder, and you need to be careful not to overheat the aluminum.


Overall, pulse tig welding is an efficient, versatile welding process used for various applications. It offers many advantages over other welding processes, including high-quality welds, low heat input, and reduced distortion. 

Pulse tig welding is becoming increasingly popular among welders thanks to its many benefits.
