TIG welding machines are categories into two types.
- DC TIG welders
- AC TIG welders
There are specific differences between them; let me discuss them one by one.
DC TIG welders
Direct current TIG machines are those in which the current streams just one way.
In this kind of TIG welder machine, the light is associated with the welder machine’s negative yield and the work return link to the festive hub.
and as the current begins streaming when the curve or circuit finishes, the warmth starts appropriating in the circular segment 33 percent (according to specialists) in the opposing end associated while the excess 67% on the positive side.
That is the component needed in these welding machines, which makes them operational.
AC TIG Welders
When operating with a TIG machine that uses Alternative Current (AC) mode, the current
given by the welding inverter works with either positive or negative elements of half-cycles.
Throughout this unit, the current flows through one direction (positive or negative) and streams from the contrary direction (negative or positive) at an alternate time. Just at the point where both positive and negative joins together, these fulfill one loop, and the device is known as the Alternative Current, and that is why they are known as the AC TIG welding machines.
Moreover when a loop completes within a second, it is known as a relapse; the larger the recurrence, the greater the weld’s strength.
Let’s begin with MIG
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
- Easy to use and master the art
- No special skills are required to work.Â
- Quickly can work on thin sheets.
- No slag
- 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.
Moreover 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.
- Provides strong, quality, and precise welding
- Can weld rigid material with ease.
- TIG machine work with different voltages (110V/ 120V)
- Hazardous fumes fumestive
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.
- Very affordable
- No gas required for welding
- Easy to operate
- Change of electrode is easy
- Electrode needs to be changed regularly
- Does not work effectively on high-density materials
