Welding device
First Claim
1. A device for welding by resistance, comprising:
- a body base from which extend one or more parallel columns, there being an electrode on at least one of the columns with one pole connected to a welding electric current generator and on at least one column a positioning device for a part to be welded, wherein the electrode is introduced in said positioning device for the compression of said part to be welded onto a second part to be welded against a second electrode;
a spring or expansion element in a rear position to the electrode and coaxial with the axis of movement of the electrode, the spring to exercise the compression force in the welding; and
an intermediary coupling part between the positioning device and the column on which it is positioned.

Abstract
IMPROVED RESISTANCE WELDING DEVICE that includes a mobile electrode in a support assisted by a spring, gas cylinder or expansion element, allowing its movement on being compressed so that the time lapse for the welding is sufficiently long to be effective, without altering the movement cycle of the press into which it is installed. The support has one or several columns, the electrode being supported sliding along one and with a rod housed on the inside of a positioning device, also axially movable, into which the small parts to be welded are received through a conduit. The positioning device, made from an insulated material, preferably ceramic, has some fixing clamps for said part until the welding is made pushed by the electrode rod through a lower window.
