I run my MIG welder plugged into a normal 13A socket 
My MCB is rated 16A, C curve. It has never tripped. Wires haven't caught fire, socket hasn't melted.
Anyway, I weld maybe max 3 mm thickness maximum. The amps used at this level is relatively low. Power is the important consideration. If the 13A socket provides 3000 Watts (230V x 13A) then the welding set can also weld at 3000W, but the welding set is low voltage at about 20V only. So 3000W / 20V = 150A. Assuming the welding set is 80% efficient, 150A x 0.8 = 120A welding current.
That is why you can run a welding set from a 13A socket, if the welding current that you need is low. This will not be possible if you are welding thick material, at maximum Amps. But welding thin material with a current of 80A.... sure, go ahead.
MIG welding in M'sia uses straight CO2, not a mixed gas. I have 2 tanks, one from the hardware shop made of steel, and my own alloy one (lighter) for when I need to travel someplace to weld. The hardware shop tank is replaced like your cooking gas tank; you give the empty tank to the shop, and you pay and collect a new full one. This available gas, and the fact that you can't easily find stainless steel welding wire, is the reason I say you can't reasonably weld s/steel with a MIG process in M'sia.
So, since you asked about MIG, that is the info I have for you.
You are correct about TIG welding, in that it is a "nicer" process. The same power rules apply to your welding current, and using a 13A socket at home. There is no special requirement with keeping Argon tanks, just that they must be secured, like all tanks should be. Other than that, no special precautions needs to be taken.
CAUTION! Argon is heavier than air, and does not support life!
I find the TIG process more elegant, and would like to own a set one day. Unfortunately, I want to build an aluminium boat, so the RM 6k entry price is a barrier for me, for what is basically a hobby!
TIG has it's own issues. Among them would be cost of materials, cost of consumables, learning curve, slow process, needing accurate parts (TIG doesn't like gaps between pieces) and material cleaning and preparation. But, it looks really good, and is the only real process for doing s/s and Al. Maybe one day...
I think the welding machine quality matters too. I bought 1 stick weld machine like RM100+. It tripped like hell when I weld continuously. My MCB is rated 16A, C curve. It has never tripped.

Yeah, TIG might be hard and might takes some cost to learn until you can do a product properly. But that's ok for me, life is about learning
