During brazing pull
back line insulation.
Heat area 1. As the tube approaches brazing temperature:
Heat area 2 until braze temperature is attained. It is necessary
to heat the tube evenly. Move the torch up and down and
rotating around the tube.
Add braze material to the joint while moving the torch around
the joint to flow braze material around the circumference.
Then heat area 3. This will draw the brazing material down into
the joint.
