ABSTRACT:
An electrical connector for a manual welding machine includes first and second contacts each having a frustoconical surface thereon engageable with one another for carrying high amperage current between the first and second contacts; one of the contacts connects to a kickless cable and the other of the contacts connects to a welding head; the contacts include a self-contained lockup mechanism concentrically within the first and second contacts for pulling the contacts together as they are initially mated to impose an amplified axial force therebetween which is amplified further in a direction transverse to the axial force to produce a contact pressure between the frustoconical surfaces of the first and second contacts of a magnitude to assure low resistance flow of high amperage welding current.
