What are the types of TIG welders?

Look around the workshop and you’ll spot a few different types of TIG welders. It can be tough to decide which one is right for you. In this blog post, we will discuss the different types of TIG welders and what each one is best suited for. We will also look at some tips on how to choose the right TIG welder that works best for you and your project.

Types of TIG welders

There are several types of TIG welders to choose from, and each has its advantages and disadvantages. Let’s have a look at each type one by one, and compare the strengths, and weaknesses, to help you make the right decision.

  1. DC TIG welders
  2. AC TIG welders

There are specific differences between them; let me discuss them one by one.

DC TIG welders

Types of TIG welders
Square Wave TIG 200, Compact Inverter TIG Welder. See our review

Direct current TIG machines are those in which the current flows only one way. The light is connected with the negative yield and work return link of this kind of TIG welder machine to the festive hub.

The current begins to flow when the curve or circuit has been completed, and the heat begins to appropriate in the circular part at 33 percent (according to experts) at the opposing end, while the excess 67 percent is on the positive side.

AC TIG Welders

For AC only TIG welders, the current sent by the welding inverter works with either positive or negative components of half-cycles.

If a current flows in only one direction (positive or negative) and streams from the reverse direction (negative or positive) at an alternate moment, you’re looking at an AC TIG welder. When both positive and negative cables come into contact with each other, they form one loop, and the equipment is known as the Alternative Current.

Typically, the size of a weld, or the amount of space it occupies within a component and in the surrounding area, is measured on the so called “length scale”. The length scale for any given material is defined by measuring intervals as long as possible (pressure welds are not recommended due to their strength).

TIG vs MIG welding

It’s one of the most commonly used welding techniques, also known as Gas Metal Arc welding. In this technique, an electrode (tungsten) is attached to the welding gun, which works as a conductor. 
There should be a protective air bubble around the circular electrical section and a liquefied metal puddle for a wide variety of welding to cover the environment and deterioration. In this case, we use remotely supplied protective gas, and the most widely used gases for this object are CO2, Argon, Helium, or a combination of them

Positive
  • Easy to use and master the art
  • No special skills are required to work. 
  • Quickly can work on thin sheets.
  • No slag
Negatives
  • Cost of gas
  • Cannot work in windy conditions.

TIG (Tungsten Inert Gas)

TIG is the short form of inert tungsten gas. This technique has a tungsten electrode used to transfer the current into the electric Arc to weld. 

Tungsten and welding puddles are preserved and cooled with latent gas, usually argon and TIG welding is probably comparable to oxy-acetylene forging in with the ultimate aim of using a filler material for development or bracing.

Positive
  • Provides strong, quality, and precise welding
  • Can weld rigid material with ease.
  • TIG machine work with different voltages (110V/ 120V)
Negatives
  • Hazardous fumes fumestive

Other types of welding

STICK or MMA welding

It is the most traditional way of welding in MMA welding (manual metal arc welding). Moreover this technique uses a replaceable electrode that is when connected to the flux weld.

It uses an electric current to create an arc between the metal that is to be weld and the electrode. Both these combine to form a foam-like mixture that cools down to create a welding joint between two materials or points.

Positive
  • Very affordable
  • No gas required for welding
  • Easy to operate
  • Change of electrode is easy
Negatives
  • Electrode needs to be changed regularly
  • Does not work effectively on high-density materials
