MODEL: WCD - 06 / 08 SERIES: The Capacitor Discharge type welding being a highly
versatile process of welding studs, pins and other fasteners, overcomes
the conventional method of through bolting, tapping, hand welding or
riveting process. When consistently reliable and accurate welding
applications are required in fabrication of control panels, automobile
body building, rail coaches, testing equipments, insulation or any other
such crucial applications, WELDCRAFT'S Capacitor Discharge stud welder
brings the design to reality.
Not influenced by
variations in power supply voltage. The weld base is always stronger
than the stud / base material. Consistent high weld quality and better
Capacitor Discharge stud welder uses a low voltage electrostatic storage
system in which the weld energy is stored in a capacitor of high
The CD-Studs or fasteners have a small, specially engineered tip at the
weld end. Once the welding current and the required spring force is set
to suit the diameter of the stud, the fastener to be welded is loaded
into the collect of the welding gun and is positioned in contact with
the work piece.
When the switch on the
welding gun is activated to start the welding sequence, the
energy stored in the capacitor bank is discharged through the small
tip, which rapidly disintegrates, creating an arc, which heats the
surfaces of the stud and the work piece.
During arcing the stud
is kept pressed against the base material by a spring action.
When the two surfaces are in contact, fusion takes place and weld is
produced between the stud & the work piece, thus completing the total
weld process within a few milliseconds.
