New To Welding? How TIG Is Different From MIG So You Can Choose What Is Best

Posted on: 1 September 2016

If you are new to welding, you will have to use different types of welding equipment. Two types you may come across is MIG and TIG welding. If these mean nothing to you now, below is some information about them. This will allow you to choose the type of welding equipment that would work best for you and the job you are doing.

MIG Welding

MIG welding, also known as Gas Metal Arc Welding, allows you to weld both thin to thick materials. MIG welding is only semi-automatic. This is because the welding machine continuously fills the joint that is being welding, but still requires some skill from you.

A machine first feeds the wire into an electrically charged contact tip, and then the wire is fed into the MIG gun. The contact tip transfers the current from the welder to the wire. The wire burns and melts the metals together. You can weld a variety of materials, such as aluminum, stainless steel, and mild steel.

You can choose gasless MIG or gas MIG. With gasless, you will not have to worry about having shielding gas, and it is more portable because you will have no gas to transport. A gas MIG gives you very clean welds with no spatter or slag, but it is less portable.

TIG Welding

TIG welding, known as Tungsten Inert Gas, would be a good choice if you weld thin gauge materials. You will also hear TIG welding called Gas Tungsten Arc Welding. While using this welder, a non-consumable electrode delivers the electrical current to the welding arc. An inert gas, usually argon gas, protects and cools the tungsten and weld puddle.

One of the main benefits of a TIG welder is you can keep the power very low so you will not have to worry about blowing through the metal you are welding.

If you need to weld heavier metals, such as pipes, make sure the TIG welder you purchase has enough power output to handle this job. Tell the salesperson where you are purchasing your welder what you will be using it for, so they can help you choose the right power output.

You can use a TIG welder to weld titanium and copper, and it works well if you need to make some trickier welds, such as round or s-curve things.

No matter which you choose, you need to make sure you are properly trained before you use the welder to prevent accidents.
