There are plenty of bargains you can find when you decide to go for a Used Harley Davidson in Pittsburgh. If you do your inspection correctly, you could end up with a quality motorcycle at a great price. Before purchasing a used motorcycle, be sure to take it on a test ride as this will give you a unique opportunity to evaluate its performance. The state of the bike’s frame will tell you a lot about the care it has received from previous owners. As a precaution, you should never buy a motorcycle with dents, cracks or kinks on its frame without asking what caused them.

Getting information from the bike seller on why he is selling it and where it is taken for regular maintenance can help create a better picture of whether the bike is what you are looking for, and if it will work well. Looking at maintenance records and inquiring on important issues such as if it has been winterized is also crucial.

It also helps to have the bike inspected at an accredited motorcycle repair shop so as to figure out if it has any mechanical problems. A test ride will allow you to check if the brakes work properly or if there are any signs of the brakes pulsating, which would indicate the brake disks are wrapped. Be sure to accelerate through the gears so as to determine if the transmission is smooth and firm. A test drive will also help you notice any weird engine noises, creaking in the suspension or excessive vibrations and it will give you a chance to see how the bike responds to steering. Ask the seller about anything out of the ordinary so that you can know in advance if the bike will require repairs after you purchase it.

Purchasing a Used Harley Davidson in Pittsburgh carries its risks, but you stand a good chance of landing a great bike that will serve you for many years, and save you money. Being keen on inspections and inquiring about all unclear aspects will ensure you find and buy a quality bike on Z & M Cycle Sales.

Overview of Metal Inert Gas (MIG) Welding

There are many types of welding that are available to learn today and MIG is one of those types. This type of welding dates back to 1940s when it was discovered to weld aluminum and other types of non-ferrous metals.

Many people refer to MIG welding as GMAW or gas metal arc welding. Often these two terms are used interchangeably. This type of welding is considered to be automatic or semi-automatic because it happens quickly. The process works to join two pieces of metal by continuously passing a wire through a welding gun. The wire is connected to a direct current and then passed through the gun with an inert gas like Argon.

The wire acts as an electrode and the inert gas acts as a shield as the welding is performed. This means that contaminates are air borne instead of being put into the weld zone.

An MIG welder will use this method to meld metal quicker than regular stick welding especially when they want to weld soft metals like aluminum. When this method was first started the inert gas was too expensive to do the process all the time. Today, carbon dioxide can be used instead of the more expensive gases and makes this method more cost effective.

Advantages of MIG Welding

There are several advantages of MIG welders:

* It is faster than traditional methods of welding and it produces longer, continuous welds.

* It produces a cleaner weld with less splatter.

* It can be used with a wide variety of alloys and metals which makes it a versatile elder process.

Disadvantages of MIG Welding:

Although this is a very specialized process that works efficiently for many projects there are a few disadvantages that include:

* The welding equipment is complex and bulky to use.

* The equipment needs a source of continuous current and a constant feeding of the wire through the gun.

* It is a very different process than traditional welding so there is a learning curve for all welders who use this technique.

* Because of the inert gas, MIG welding cannot be used an open area because the wind would cause the gas to cause more problems for the MIG welder.

MIG welding has become very important in many industries because of its ability to weld metals quickly. You will see this type of welding done in many industries that include automobile industry and nuclear industries.
