Buy a MIG welder.
It gives you the option of welding Stainless and Aluminium as well. It is a bit more practical than a TIG, just for everyday use.
Now the welder you are looking at has a flux-coated wire. It is not the easiest way to weld and tends to cause a lot of spatter.
Get a welder that uses gas to protect the weld pool instead. They are cheap enough.
If at all possible buy a welder that has a wire feed unit separate from the main welder. You will understand this every time the torch is not able to reach where you want and you have to keep moving the welder around the place, so the separate unit cuts out all that.
Now welding with the MIG is fairly simple.
You should be able to judge by the sound it makes on the wire setting. When welding and the wire sounds more of a buzz with a very bright glow the wire feed is probably to low. It should make more of a crackle noise when welding. If you mess about with the wire settings you will understand what I am trying to explain.
What I usually do is get a scrap piece and turn the wire up high, start welding and keep turning the wire down at the same time until it stops forcing your hand back. If the wire is too high it will not melt and will push the torch back.
If the metal is very thin keep the plant down to a low setting, if you find that it is melting away on you, keep spot welding letting each spot cool before you do the next one, don’t worry if it looks bad, it can always be sanded down. Also if it is a long weld on light materials, do a small bit and let it cool completely, otherwise it will warp with too much heat.
Hope this is some help to ya
