Dear Sirs: Any idea as to where I can find the suggested manf. technique for sodering 6 Copper pipe. I understand that it requires a totally different approach than the smaller diameters. Thank You. Neal

Large diameter tube is is soldered in a similiar manner to small, however, even heating of the entire joint is the toughest part if the job. If you have one, a ring torch from prestolite is a great tool for this, they were made in the heyday of copper dwv, and had 6 or 8 flames to heat the joint from all sides. If you are using a rosebud, or large LP/air, KEEP THE FLAME MOVING. An overheated area will cause a solder fallout and potential leak. The use of solders with a wide pasty range can help, such as Harris Bridget You may want to check the Copper Development Associations website The Copper Page
