Step 1: Connect the red welding torch hose to the acetylene tank
The acetylene tank is used for starting the flame and the oxygen tank is used to continue feeding the flame and to control the intensity of the flame. -
Step 2: and the black hose to the oxygen tank.
Wearing safety goggles is a precaution necessary to ensure eye safety anytime you are working with open flames. , Only turn the valve halfway to ensure that there is enough acetylene to start the flame, but not so much that it will be too large. ,, A blue colored flame indicates that the flame is close to the ideal temperature for annealing copper.
A flame that is too hot will burn the copper, while a flame that is too cool will not be strong enough to change the copper's properties like durability and malleability. , Constantly moving the flame will help to avoid burning the copper.
Copper that is glowing cherry red is at the correct temperature for annealing purposes. ,, Turning the valves back to their closed positions will ensure that the flame is extinguished.
It is a safety precaution so that you can freely work with the copper without worry. , Use the pliers to remove the copper from the bucket of water once it returns to its original color.
The copper is now annealed and will be soft and malleable for working. , -
Step 3: Put on your safety goggles.
-
Step 4: Switch on the acetylene by turning the valve halfway.
-
Step 5: Ignite the gas by pulling the trigger on the flint lighter in close proximity to the hose head until you see an orange-red flame.
-
Step 6: Slowly turn the valve on the oxygen tank until the flame turns blue.
-
Step 7: Aim the flame at the copper you wish to anneal
-
Step 8: constantly moving the flame over the surface of the copper until the entire area glows cherry red.
-
Step 9: Turn the oxygen valve back to its closed position.
-
Step 10: Turn the acetylene valve back to its closed position.
-
Step 11: Use pliers to grip the copper and place it into a bucket of cold water.
-
Step 12: Finished.
