An impact wrench is a socket wrench control power which is used to generate high torque. There is a minimum exertion by the user. This high torque is delivered suddenly to the output torque. The compressed air is certainly the most important power source but the electric as well as the hydraulic power are also very common and used frequently. The cordless electric devices are also very popular in the recent times.
There are some points to consider however, when using, and more importantly, buying an air impact wrench. Probably the most touched upon issue and concern when purchasing an air wrench is whether or not the impact wrench you are getting, is the not only suitable to your specific needs, but also for the optimal output of the tool in general.
Finally, a common mistake is to under-estimate how much power you'll need. Taking off the wheels on your car is a common example. The manufacturers recommended torque for your lug nuts is probably between 80-140 ft-lbs, so people will "play it safe" and get a wrench with a 220 ft-lb max torque. The problem with this is firstly that the max torque in an impact wrench is always more than your "working torque", and not all companies give out that information.
A wrench is used for fastening and loosening of nuts and bolts. A basic wrench is limited in the function where it cannot be used to perform heavy duty operations. With technological developments, in order to use a wrench to perform tougher operations, these wrenches have emerged as the hybrid of the common wrench. It is known by several other names like impactor, rattle gun, air gun, air wrench, torque gun, etc. These days, they are available in variety of sizes, styles, and shapes and can be chosen depending upon the usage and requirement.
The other problem is that you are not taking into account any real life factors, like rust and other weathering, that will make your lug nuts harder to get off. For most cars and light trucks I recommend a wrench with a max torque of 4-500 pounds, just to make sure you've got enough (it would suck to have to manually break each of your lug nuts because your new impact wrench isn't powerful enough).
