What is MIG Welder and Different Types of MIG Welder

A MIG welder, also known as a gas metal arc welder (GMAW), is a welding equipment that utilizes a wire terminal and a bend to join two metal pieces. The wire terminal is taken care of through a welding firearm associated with a power source. At the point when the trigger on the welding weapon is pressed, an electric flow courses through the terminal and makes a bend. This curve softens the metal, and the liquid metal joins the two bits of metal together. The MIG welder likewise utilizes a safeguarding gas to shield the weld from pollution and to settle the circular segment.

Including automotive, construction, and manufacturing. Including car, development, and assembling. They are especially valuable for flimsy welding materials and in restricted spaces where getting to the weld is troublesome. MIG welding is likewise somewhat simple to learn contrasted with different kinds of welding, pursuing it a famous decision for specialists and home studios.

Different Types of MIG Welder

There are following different Types of MIG Welder.

  • Gas metal arc welding (GMAW)
  • Flux-cored arc welding (FCAW)
  • Metal active gas welding (MAG)
  • Pulse MIG welding
  • Choosing the right MIG welder for your project

Gas metal arc welding (GMAW)

Gas metal bend welding, also known as GMAW, is a well-known welding process for metal fixing and manufacturing. It is known for being pragmatic and easy to dominate, seeking after it a good choice for those new to welding. In GMAW, an electric curve breaks down the base metal and filler material, which are joined. The welder uses light to give heat and a continuous stream to the joint between the base and filler materials. One of the upsides of GMAW is that it allows the welder to work on compound joints with different layers while keeping their hands clear of the welding locale. That infers they need to hold no parts set up during the welding framework, making it a more useful and safer welding method.

Flux-cored arc welding (FCAW)

Flux-cored arc welding (FCAW) is a MIG welder that utilizes a consumable wire. The wire is canvassed in motion, which shields it from oxidation and intensity. When you use an FCAW machine, the transition streams into your weld pool as it melts and streams into the joint between two metal pieces. The protection from this stream makes it hard for liquid metal to get away from through breaks or openings in your welds.

The power input into an FCAW machine goes from 300 amps up to 1,000 amps depending upon what sort of cathode you’re utilizing: carbon poles produce more intensity than tungsten bars since they move more energy per unit region when they’re presented to current. Interestingly, tungsten cathodes function admirably at high amperages yet require less voltage than carbon poles whenever utilized with AC sources like basic electrical cables (AC/DC).

Metal active gas welding (MAG)

Metal active gas welding (MAG) is a variation of MIG welding. It uses a metal electrode and gases heated by the arc between the electrodes rather than by electricity. With this method, the job can be completed much faster than with other types of MIG welding. When it comes to large sections or hard metals like stainless steel, MAG is often used because it produces high-quality welds that are much more durable than those made with AC voltage MIG equipment.

Pulse MIG welding

Pulse MIG welding is a type of MIG welding that uses a pulsed electric current, which allows the welder to weld thick materials. This process works well with stainless steel, aluminum MIG welder and most alloys. It can be used with various metals and is often preferred over other methods because it doesn’t require using a special clamping device or protective gloves while in operation.

Although there aren’t many differences between MAG and AC voltage jobs when it comes down to what needs doing (it’s all about maintaining proper safety), there are some technical specifics worth noting.

Choosing the right MIG welder for your project

Choosing the right MIG welder for your project can be an overwhelming errand. You might have heard that MIG welding is quick and basic, yet what’s the significance here? This article will make sense of how MIG welding functions and why it’s an amazing decision for metalworking projects.

We’ll likewise talk about the various kinds of mig welders accessible today, including their advantages and disadvantages, so you can make an educated choice before buying one.


It is easy to choosing the right MIG welder is an important decision that can affect your project’s success. It requires you to consider the type of metal being welded, the welding application, and more. We hope this article helped help you understand some of these terms and their differences!
