Types of Mig Welders

mig weldersThere are various types of welders  but there is one in particular which is used much more than others. One of the most used welders  is the MIG welder which unlike many other types is a wire feed welding machine. This is in contrast to welding methods that make use of a stick or electrode, and it is generally much more efficient for general purpose welding.

When looking for a MIG welder you will generally hear it called by a number of different names and sometimes it can be difficult to tell exactly what it is you are purchasing. That being the case, take this list into consideration when you are looking for a MIG welder, and remember that a MIG welder by any other name is still a MIG welder:

  • Metal Inert Gas (MIG)
  • Metal In Gas
  • Gasless Mig Welder
  • Wire Feed Welder
  • Mas Metal Arc Welding

Process Notes

Throughout the welding process the weld puddle will be shielded by a gas known as the Inert Gas or Active Gas. It is possible to use a wire without a shielding gas, and this process will be known as Gas-less wire Welding. Argon Gas is the most common type of shielding gas used in because it does not have any reaction to the MIG welding process and is therefore safe to use.

Gas-less MIG welders are normally only used by home users who operate outside on a regular basis. Note however that these can also be used on job sites and other outdoor locales. The benefit of using a gas-less MIG setup  is that one would not need to worry about wind blowing the shielding gas aside and creating a hazard during the welding process.


MIG Welders can be used for a number of different applications. For instance you will find that they are used in both the professional and personal circles for virtually any project. From professional vehicle plants to the garage where you are working with wrought iron, these types of welder have a home anywhere.

Power Requirements

Meeting power requirements for the purpose of a MIG welder is not difficult so long as your working area meets the standards.

Power Approximations:

Single Phase MIG Welder: 230-250 Volts

Three-Phase MIG Welder: 400-420 Volts

The power outlet for a MIG welder will need to be considerably bigger than your standard outlet. This of course is to handle the start up current, or that initial power surge as you activate the device. Note that industrial machines will create a larger power surge, and there is a strong chance that you have seen these outlets on several other devices around the house. The majority of standard house plugs will not have the amperage to handle a MIG welder which means you will need to seek out higher amperages. If you are not an experienced electrician it would be in your best interest to call on professional help.
