摘要

Improvements introduced in the object of the main patent of invention no. 432.632 by: automatic system of voltage cutting in electric welding equipment, characterized in that in the section that bypasses the branches of force that feed the primary winding of the auxiliary transformer, according to the second claim of the main patent, and interleaved between the contactor that drives the power switch and the timed contact of the relay incorporated in the output to the electrode holder clamp of the secondary of the auxiliary transformer, a contact is incorporated normally closed and with timing to the opening, the aforementioned variable relay between 3 and 5 minutes, so that once the arc has been started, it will take 3 to 5 minutes to disconnect the group from the moment the relay is activated, allowing any electrode to be fused without interrupting the arc, while if by carelessness or other cause, the clamp makes contact with mass, in that t time selected, the group is automatically disconnected.
