(1) Welding with Silver
Silver solder is an alloy composed primarily of silver and copper. It is used to bind iron, copper or copper alloy. It is relatively expensive, but with excellent welding results.
(2) Phosphor bronze welding
Phosphor bronze is generally used to join copper or copper alloy.
(3) Low temperature welding
Low temperature solder, called a welder, is an alloy of tin and lead. As it is not very adhesive, do not use it in refrigerant tubes.
Note: (1) Phosphor bronze solder tends to react to sulfur and produces a solution made up of very fragile water, which may cause a gas leak. For this reason, use any other type of solder in hot places and cover the surface with paint.
(2) When welding when servicing, use the same type of welding.
