Mig welding, also called wire feed welding, costs less and takes less time than other techniques of welding.

Automated robots are used in manufacturing facilities to perform repetitive mig welding tasks. They are used to manufacture cars, trucks, boats and a whole other range of miscellaneous items. Because it is faster than tig or stick it makes it an ideal candidate for automation.

The fancy name for this is called Gas Metal Arc Welding or GMAW for short.

It is nothing more than the continuous feeding all of electrically charged wire which carries a current and a voltage to the welding puddle. Because it keeps feeding in and there is always in electricity there it is a never ending cycle. It will keep putting down filler material until the user lets go of the trigger.

It’s a preferred technique these days; here are few reasons for that:

1. Is reasonably simple to do.

2. The action of mig welding requires a lot less time as compared to the stick or tig welding process.

3. Is less expensive and more economical.

4. To increase productivity and throughput semi automated or fully automated devices can be fitted.

5. Can be used with or without a shielding gas.

The shielding gas provides you with better control over the spatter of the molten pool of metal that is created. A variety of gases can currently be selected for this type of welding.

A MIG welder can work with nearly all kinds of metals. Mild steel and aluminum are popular metals used in this welding process.

Before you buy a machine you need to first think about what you plan to weld with it. As the thicker the metal the more power you are going to need.

After deciding on what will be the main thickness and type of materials you plan to work with you can then start to research what machine to buy. I would suggest that you got a unit that is slightly bigger than what you need right now, as no doubt there will come a day when you wished you had. If you get a bigger one, your duty cycle will also be better and this will allow you to keep welding for that little bit longer.

So now that we have the power source unit selected you’re going to need to stock up on some basic consumables. Your consumables are things that are consumed over time thus the name consumables. You’re going to need to keep a small supply of items such as spare contact tips or contact tubes as they are called in the UK. Making sure that you use the correct size tip for the correct sized wire. Also you’re going to have to have some spare nozzles or shrouds, insulators, tip holders, gas diffusers and possibly a liner.

It is possible to mig weld stainless steel, aluminum, mild steel, high tensile steel and all other sorts of metals. But the most common welded materials are mild steel, stainless steel and aluminium as using the mig welding process makes it very easy.
