Poking about on the mig welding forum I was advised that gasless was a bit messy and that I should go for gas which ended up being a bit more then i really wanted to pay, although im not sure they got the message that it was likely to be attacked by all varieties of weapons so didnt really matter too much about neatness.

Im planning on going to night classes to learn to weld soon though so hopefully I will have more of an idea after Ive done that
