SAFETY FIRST

• Please always ensure that you take notice of fire extinguisher locations, and notice the exit points in the event of an emergency.
• When brazing, always be aware of your surroundings as well as the direction your flame is facing. 
• Remember, the flame is incredibly hot and can cause injury or hazardous situations in seconds.
• If you have flushed a system with BENZINE, ensure that there is no residual benzine remaining in the system.
• Always be AWARE!

Prepare your work

Before brazing, it is best to perform all the necessary cutting, bending and pipe fittings before brazing for the following reasons.

1. Mistakes can be rectified easily when the components are loose.
2. You can ensure that all fittings and pipe locations are neat and professional.
3. The operation of brazing equipment can be done once and packed away, which is safer.

Brazing Preparation

1. Pipes and joints should be sanded with P100 Sandpaper. You can also take a cloth dipped in Benzene to wipe any grease or grime off the brazing area.
2. Check that your working area is clear from all obstructions, and unnecessary tools or hazards.
3. A well-damp cloth strip should be kept close by in order to cool and clean the braze.
4. Keep tools close by as well as the brazing rods. This prevents too many distractions while the flame is lit.

 Brazing Tips

1. Wrap the strips of wet cloth around the pipe to restrict the heat from moving too far. This also protects other equipment if you overheat the pipe.
2. When brazing a compressor, always wrap the pipe close to the compressor on the pipes you are brazing with wet cloths. Overheating the compressor will boil the oil rendering it useless. Overheating may also damage the delicate windings and head units.
3. Always heat from the bottom up. As heat rises, it helps give an even heat around the joint.
4. Before brazing, always remove the Shrader valve and open all the valves to release gasses caused by excessive heating.

Brazing with different alloys

Rhis chart will show which types of alloy brazing rods you should use with each type of alloy joint.

Important to remember is that brazing should be done slowly by taking your time. Practice as often as possible to get your handle on the rod and equipment.
