This a learned skill, basically it is very similar to some of the skills learned when gas welding. Both processes require a source of heat to melt the base metal and a separate source of filler material . Both require the use of two hands. The exception is when you are fuse welding. Melting the edges of two pieces to flow together.
Do you mean regular stick, also known as SMAW welding? Yes, many TIG power supplies can also be used with a regular stinger to burn rod. In fact, it makes the process easier, because you can usually run the high-freq to make starting the arc a real breeze. Check the manual for your particular model to be sure it is allowed. You will have to disconnect the TIG torch and hose/cable, and get a regular cable and stinger (rod holder).
When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
It depends on what you're welding and what kind of weld you need. For an extremely strong weld where you don't want to transfer as much heat to the surrounding areas, tig is the way to go. Tig has the option of melting only the source material (together), so if it is better than no material is added, then tig is the better process. If you want a small, uniform weld, then tig is also superior. Mig is wire-feed and so adds material to the pieces being welded. So it is better for filling areas or adding superior strength. If the material surrounding the weld can take the heat or doesn't matter if it is deformed or discolored, then mig welding is the way to go. A good discussion of Tig and Mig welding is here http://www.ridgecrest.ca.us/~biesiade/weld.htm.
Aluminum is one example of a metal that cannot be MIG welded and must be TIG welded. The limitation of MIG is usually the heat it can produce versus thickness of the material. One quarter-inch thickness is usually about as thick as you can weld with either MIG or flux-core wire feed welders. Anything else will require the heat energy available with a stick welder.
Yes In fact Miller includes a table for Copper TIG welding in its charts. Similar setup to steel but almost double the power. Copper dissipates the heat faster so you need to put it in faster. Local welding supply place carries filler rod (I think it has higher silicon to help flow).

can weld aluminium with a mig or tig welder
Silicon is added to the tig rods in production. Use a gas weld rod which does not have the silicon and the weld will be full of porosity.
The three ways you would weld stainless steel are; 1. laser 2. friction 3. TIG Only TIG should be considered for nonproduction welding.
Miller TIG system are well used systems. The Miller TIG systems are used for welding, calculating the costs of welding and materials, and showing how to weld.
Argon gas is an inert gas and it shields the weld from any contamination from the out side air. It shields the weld and makes it cleaner and stronger.
One method is Ultra Sonic Sound, another Die Penetration.

Tig is always done in straight polarity, i.e. electrode negative. reason: almost 2/3rd of the heat is generated in positive terminal of weld, in this case the base metal and the rest in the negative terminal, in this case the tungsten electrode. Also you don't want to deposit the tungsten electrode in the weld, do you?
A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.
