floor pans

I'm getting ahead of myself, I should have the floor pans this week, but after reading the discussion about glueing or welding , i will be learning to weld. Is this very difficult as I have never had a desire to learn to weld. Also, someone had said you could purchase an inexpensive welder and needed equipment from Harbor Tools. What would I be looking to purchase? I don't have a clue what I am looking for, so thanks for helping. Is there a tutoral somewhere which may give me insite into what I am doing. I'm not in a hurry, As this project is into it's second year now.
