Here are some more information for Mig Wire:
So here is the deal! You have a car and it needs new metal put in. Yeah, you could go with body filler, but what about parts like the chassis? If you have a MIG welder it can help you do all metal joining repairs. Some people like to gas weld or even stick weld, but the main problem with those welding processes is distortion! MIG is clean, fast, and works great with the thin metals that are used on cars, plus it is what most body shops use! The down side is you need to buy, rent or borrow one of these machines. For a few hundred dollars you can easily find one for sale, and in the worst case you can pick up a real nice pre-owned machine!
MIG welding on cars is pretty easy. All you need is the machine and the filler wire. When it comes to filler wire there are two ways to go. Solid wire or a self shielding wire. There are pros and cons to both choices. The solid wire makes a cleaner weld, but that also means you need to get a bottle of CO2. The self shielding wire does not need any gas, but the welds need to be cleaned more after they are finished. Either way, it beats using body filler to patch up holes!
Set up of the machine depends upon the metal you are welding and it's thickness. It is recommended that you first select a piece of scrap metal that is the same thickness and type of metal as the one you will be welding and practice welding on the scrap. Set the machine so that when it is welding it has a fast crackling sound to it. Once you've got it down, it's time to prepare your car's metal.
Prep work for metal repairs on cars requires cleaning the joint so that only clean steel is showing. This is not just for cars but MIG welding in general. You want everything fit up as tight as possible so that there are no gaps. Another thing to look out for before getting started is anything flammable in your work area. The last thing you want to do is set your garage on fire!
Now you are ready to weld. When welding thin metals, the only technique employed is that of a whipping motion. Simply point the MIG gun and pull the trigger as you wave it back and forth until you fuse the edges of the joint together. Once you're finished with the welds, grind down the welds until they are flush with your vehicle's surface. Those are the basics of MIG welding for your car restoration needs! Safe welding!

Guidelines for MIG welding aluminum
MIG welding is a kind of arc welding that uses a metal electrode to match the alloy of the work section and an inert gas to transfer oxygen from the weld region. MIG welding is the most suitable welding technique for aluminum, with the exception of particularly thin aluminum sheeting. MIG welding aluminum needs more practice and skill than welding steel.
Prepare the surfaces of the aluminum elements by cleaning the exterior with a solvent, then using the wire brush to remove any oxides. This removes any constituent part and impurities and prevents them from becoming trapped in the weld.
Clutch the electrode at a 10- to 15-degree angle from the vertical, sharp toward the way of the weld. It is significant to use the push process when MIG welding aluminum. The pull process would prevent the argon gas from sufficiently covering the weld, resulting in an inconsistent weld.
Make a pool of molten aluminum with the electrode and gradually push the electrode forward. Regulate the voltage of the welding machine to get spray transfer of the aluminum electrode. In spray transfer, the electrode release small droplets of the metal into the weld. This will results in a smooth weld and the droplets do not get in the way with the electrode arc.
Adjust the movement speed of the electrode as the aluminum work part heats up to retain a consistent weld width. If a big fillet weld is requisite, make several thin passes as different to one thick pass, which has the potential to burn through the material.

What size wire should i be using in my Mig welder?
I am starting to learn some welding on my own.I just bought a small 130amp mig welder a while back to try out my welding technique.So far i stink!LOL! I am not using a shielding gas but using flux core wire.What size wire should i be using? I have been practicing with .030. How do i know what size i need? Is .030 a good all round size? I dont know squat about welding but i want to learn more.
Yeah Yeah i know you pros out there are saying "your welders too small" or "you need to be using a shielding gas".OK fine but i'm just learning! Let me start small and work my way up! 
all good answers!!
I will let this vote!Thanks.
yeah thats perfect to be workin with. adjust the heat and wire speed as you need to play with it but you cant do to thick of a metal with that its more of a body panel thikness but it can do some a little thicker just play with it on a couple of scrap peices to get it down.
Tejas LCA project to cost more than Rs 13,000 crore over 35 years
The overall developmental cost of Tejas Light Combat Aircraft has quietly zoomed past the Rs 13,000-crore mark, with the government sanctioning the extension of the fighter's "full-scale engineering development'' till Dec 31, 2018.
