Cut out the damaged section. Cut a new piece of tube. Clean the ends of the tube to be joined (4) with wire wool, and smear on a bit of LaCo flux. Slip on the new section using capilliary couplings (with a smear of flux in 'em). Warm up the joint with a gas torch or similar, apply solder until a ring of the stuff appears at the end of the coupling. Let it cool nauurally. It's really easy, though it might not sound it.
Make sure the inside of the pipe is dry (or at least isn't wet with standing/dripping water) before soldering, BTW.
