The Advantages MIG Welding:

There are a lot of advantages that MIG welding has over other welding types. Following are some of the advantages,

• First of all it is quite easy to study MIG welding. You can turn into pretty good at excellence welds in a small quantity of time. You can purchase a decent MIG welder for under $500. Also, a lot of these machines will be able to run off of a normal 110v outlet. Cleanup from a welding session is minimal.
• The next advantage is speed. Since a solid nonstop wire is used there is no require to change rods. There is also no require for chipping the weld, as the sum of slag is reduced. Quality welds can be created faster than most other welding types. You must be able to achieve a higher output of work compared to most other types of welding.
• The removal of flux in MIG welding will help prevent slag defects in the weld.
• The shield gas helps guards the arc which eliminates the need to regularly replace the electrode. This will also help prevent weld splash.
• It is easier to weld thinner materials.
• Can be used on a broad selection of metals, including stainless steel, mild steel and aluminum.
• The welding procedure can be either manual or automated.

So as you can see MIG welding has a lot of advantages that create it accessible to the beginner.

MIG Welding Safety Tips:

Welding is a proven method of permanently melding two metals together. Metal Inert Gas welding is a world renown and respected trade, however, the risks can out way the rewards of its production if the proper MIG Welder Safety guidelines are not taken. MIG Welder Safety should be the primary concern of the practitioner, novice or master, it should not matter what their skill level is, and the proper precautions should always be taken.

Some general guidelines of safety may seem common sense enough but sometimes employers may push out these guidelines, do not let them. Even if you are welding on your own, it is very important to follow all of the MIG Welder Safety precautions in order to enjoy a safe, productive experience. Some examples of safety precautions are:

Make sure that all of your skin is covered and protected from the intense UV light that is produced. Just closing your eyes for a quick tack will not insure that you will not get arc eye. (Arc eye is a very painful result of improper exposure to the welding light. The sensation of pins and needles being placed in the eye is a common description.)

Always make sure that the area you are working in has a sufficient exhaust system in place. If you have trouble with extraction, be sure to wear a breathing mask. Never have anything that is flammable anywhere near where you are working.

Never forget the basic MIG welder safety guidelines and never attempt to weld without an instructor if you are not considered a professional.

The Work Process of MIG Welder:

A mig welder runs off electricity and uses the electrical current to raise the temperature of the base metal and fuse the filler metal (MIG wire) together in an electrical arc. This is your welding process.

The electrical current is passed from the power point on the wall, into the welding power supply, through the welding torch. When the trigger is squeezed the current then travels through the contact tip onto the wire making the welding wire live and conductive.

On the part you want weld, you attach the "welding earth" lead. Then when the MIG wire touches the earthed part, the electrical circuit is complete. As a result, the electricity starts to flow making a flash of sparks and an arc is created.

This arc is welding, without it you have nothing. Remember that "arc welding" is the process of welding using electricity. Mig welding is still arc welding as it uses electricity to make an arc, it's just that we call it MIG welding.
