What is MIG Welder?
MIG (Metal Inert Gas) welding is one of the welding processes that melt and join metal pieces. MIG welding uses electric power to produce an electrical arc between the electrode wire and the metal that’s welded. The arc melts the wire, subsequently; it’s being deposited to form the weld. When the heat is withdrawn, the weld pool cools down, hardens, and produce a new piece of blended metal and the weld is achieved. The entire activity happens at the MIG torch’s nozzle, which is a hand-held device.

4 Major Types of Welding
If you’re new to welding, in all likelihood, you may not know about the different types of welding out there that you can use. Four most popular types of welding are extensively used from the many different welding types and styles. They are MIG, Stick, TIG and Flux Cored Arc welding respectively. Let’s go over the four types, in brief, to find out which one is best suited for novices.
1. TIG Welding
In TIG (Tungsten Inert Gas) welding, there is no filler material or a line feed for beginners. TIG welding heats the two metal pieces and melts them together. The capability and knack of the welders are vital for TIG welding. TIG welding is a more accurate welding exercise and a trained operator is required to operate it. TIG is normally used for smaller welds and thinner metal welding, but it’s not recommended for beginners.
2. Stick Welding
Stick welding is popularly known as Shielded Metal Arc Welding (SMAW), which is one of the oldest and famous welding methods, and a difficult welding type to master. Setups, electrical current and tip angles must be accurate, and it is challenging to learn, use and master stick welding. In stick welding, a rod is used and as it is consumed, it needs to be continually replaced. Nonetheless, as stick welding is versatile, it is useful for numerous types of metal joining, which other models can’t achieve. Regardless of whether the wind is blowing or it is raining, stick welding can be done in any type of adverse climatic conditions, which is the greatest plus point of stick welding. One needs a lot of learning and experience to master stick welding, thus, it is not recommended for beginners.
3. MIG Welding
MIG welding is easy to learn and master, and considered as a welding tool for beginners. The constant-feed wire and flawless mix of gases facilitate for a weld. Using a MIG welder, you can seamlessly work with all metal types including stainless steel, nickel and aluminium. However, MIG welding isn’t recommended for vertical and overhead welding. MIG welding is very popular because it lets you choose from diverse metal types, wire thicknesses and gasses. When you have the right equipment, MIG welding doesn’t have to perform a lot of guesswork. You just dial in the machine with the type of metal, wire and thickness – once it’s set, the equipment will run itself, offering you the best heat and wire-feed speed for the current task. Due to the filler material, MIG welding can join thicker metals and form larger beads.
4. Flux Cored Arc Welding
Flux Core Arc Welding (FCAW), is a speedier option to MIG welding. An advanced learning curve is involved in learning and mastering Flux Core, so it isn’t for the novices; however, it offers more benefits. MIG welding uses gas, but Flux Core doesn’t; instead, the continual-feed wire is coated in a flux offers the anti-contamination, which is achieved through the MIG welder’s gas bubble. The greatest benefit is that Flux Core can join impure metals without forfeiting composition. Similar to stick welding, Flux Core can be used in harsh conditions such as in the wind, but not in the rain.
To sum up, beginners can start with MIG welding and once they master it, then they can move on to the more intricate techniques such as Stick, TIG and Flux Cored Arc welding.
These days, there are a variety of small and portable MIG welders available under $1000 in Australia, which beginners can easily afford; however, they must only start using it after they have received basic learning and understanding on how to use the welding equipment.
