Metal Inert Gas (MIG) welding machines are used to join together different pieces of metal by using an electrical supply that fuses the consumer electrode filler with the base metal. This machine utilises a consumable wire, which is both the filler material and the electrode.
How MIG Welding Machines Work?
Metal inert gas welding machines leverage a continuous voltage power supply, creating an electric arc that fuses the filler wire with the base metal, which is constantly fed via the welding torch. During the process, the gun feeds an inert shielding gas that protects the weld pool from any atmospheric contaminations.
MIG welding machines are basically considered for heavy-duty fabrication projects. Hence, it is quite faster than TIG welding. It offers lower production costs and results in lesser lead times. In addition, this machine is quite easy to learn, and it generates welds that need minimal to no finishing and cleaning.
Advantages of Using MIG Welding Machines
You can use a MIG welding machine to experience the following benefits:
This welding machine comes with a versatile technique that suits multiple purposes and metal thicknesses.
The constantly fed wire promotes uninterrupted and fast welding, which results in lower production costs and shorter lead times.
MIG welding machine is known as a clean welding process because it leaves back minimal pattern and very little slag.
By using a MIG torch, you can handle vertical, horizontal and flat welding positions easily.
MIG welding machines provide one of the easiest welding techniques that you can learn easily.
Types of MIG Welding Machines
The different types of MIG welding machines are classified on the basis of their automation grade. They are:
Electric MIG welding machine: It is powered by electricity. It provides consistent arc stability.
Automatic MIG welding machine: It does not require manual intervention. It is suitable for large-scale industries.
Manual MIG welding machine: Best for small-scale or custom welding operations.
Semi-automatic MIG welding machine: It offers flexibility. It needs an operator to control the welding process.
Key Features to Consider When Choosing a MIG Welder
Whether you are a fresher who is willing to learn how to use a welding machine or a professional setting up a project that needs welding, it can be tough to choose the right MIG welding machine.
Here are some major considerations that you must take into account while purchasing your MIG welding machine:
Consider Your Needs: When choosing a MIG welding machine, acknowledge your requirements. You might need it to repair bicycles, auto parts, or multiple household tasks. Considering your objectives, you should be aware of the thickness of the metal pieces that you will be welding.
Input Power Voltage: The input power voltage is the voltage that your machine requires from the current outlet. When working on small DIY projects, you can prefer a 115V machine; however, for bigger projects, prefer a machine that comes with 220 V.
Welding Amperage: The MIG welding machine that you purchase should come with the appropriate amperage to fulfil the task you are willing to do. Hence, you are advised to purchase a machine with a little more power than you might require.
Budget: Considering your budget before purchasing an MIG welding machine will help you find one that comes with the specifications that you require and exclude the one that you don’t.
