5.4 MAKING A PIN BRAZE
STEP FOUR
Fig 4
•
The earth lead attachment must be applied to the cleaned surface to ensure
a sound electrical circuit.
•
The brazing gun must be correctly adjusted with the correct pin and ferrule
fitted.
•
Locate the brazing pin so that the pin is in the centre of the hole in the cable
lug. For vertical surfaces, the pin must be at the upper part of the hole in the
cable lug.
•
Apply sufficient pressure on the brazing gun so that you are overcoming
and fully compressing the internal spring and that full contact is made
between the ferrule, the brazing pin and cable lug onto the substrate. For
threaded pins it will be the ferrule and the brazing pin.
•
When the operator is ready to braze he should look well to one side to
protect his eyes from glare. The operator's stance should be stable enough
to enable this movement to be made without altering the critical positioning
of the gun. The operator should advise any other nearby personnel that he
is about to braze.
•
Hold the gun firmly and close the circuit by squeezing the trigger.
