MIG/TIG welds explained
WHAT’S "MIG" WELDING?
MIG-welding has become a very popular home welding system. It stands for Metal Inert Gas. The setup usually includes an electrical power supply (welding machine), a large insulated cable with a torch on the end, a ground cable with clamp and a bottle of compressed shielding gas. Inside the welding machine is a roll of thin wire on a motorized wheel. The welding is done similar to arc-welding but the wire is continuously fed through the insulated cable and out the torch/gun. When you pull the trigger of the torch/gun, the amperage melts the wire while being surrounded by the shielding gas. (It preserves the weld like flux does.) The advantage of the MIG-welding system includes a much cleaner weld than either gas or arc. It is also quite versatile and does a good job welding thin metals. There is also no electrode/rod to keep replacing. Control is said to be easy. All you do is set the amperage via a dial on the machine and the wire speed.
WHAT’S "TIG" WELDING?
TIG stands for Tungsten Inert Gas, but it is commonly called "Heli-Arc" welding. It is said to be the Rolls Royce of the welding processes. Way back when, helium was used as the shielding gas. Today, argon is the most commonly used gas. Both gases have the capacity to exclude foreign matter during welding – plus they are unable to mix with any other gases or chemicals that could combine to be detrimental to the weld. It differs from MIG in that it has a foot-operated amperage-control, a bottle of argon gas and lastly, the Tungsten electrode/rod is not consumed. Filler rod is hand-fed into the weld as needed. It also concentrates heat in a small area and is used with more of the exotic metals such as chrome moly, stainless steel and titanium. A higher operator skill is needed to make those beautiful welds. All it takes is practice. It is the weld of choice for critical applications such as race cars and aircraft. There are no flying sparks and very little smoke.

That is what "they" say. This is like exlaining to a learner driver how to drive a 5sp car. In theory it sound's easy but once the lead is handed to you..........****ty weld's.

i think relative to TIG and gas/torch welding i think the MIG is easier out of all the welding style/methods. but you are correct..MIG is not as ease as one would think. but of course practice makes perfect.
