D. Conditions of use provided and not provided
D.1 - Intended uses
The capacitor discharge welding machine was built for stud welding.
D.2 – Not provided
The capacitive discharge welder is not designed to be used at voltages and power
frequencies other than those indicated in the nameplate.
The standard welding gun must be used complete with tripod and spindles
original, there is no use of non-genuine or otherwise of different constitution or
measure.
The welding machine, as supplied, is not required for operation in automatic
cycles of welding.
Any tampering or welding gun will compromise safety.
E. Procedure
The welding process uses the fusion of a small cylindrical appendix, of basic
material, obtained under each pin, caused by the passage of a current of appropriate
intensity and for a suitable and predetermined welding time.
The solder thus obtained, due to the modest energy used not gives rise to
drawbacks of the arc welding or resistance, such as thermal stress or deformation of
the surfaces of the materials.
It will therefore be important that the appendix of the pin is not inserted into
small depressions or punch marks of the base material.
The welding machine is essentially constituted by an electronic circuit which
provides adjustment for the position of electrical capacitors to a voltage proportional
to the diameter of the pins to be welded.
A power module will, on operator command, to the provision of the discharge
current of the capacitor. On complex pin-piece basis, it will be achieved so the fusion
of the appendix of the pin and, for the slight pressure carried out on the same, the
welding, due to the solidification of the material brought to fusion.
