Abstract
A quick release mig gun tip comprises a contact tip having an exterior frusto-conical surface and external threads, and a gas diffuser having an internal frusto-conical surface and internal threads. The threads are preferably stub acme threads. The contact tip is assembled to the gas diffuser by engaging their threads until the frusto-conical surfaces mate. Large currents can be conducted through the frusto-conical surfaces and the threads without causing excessive resistance heating. The contact tip threads are designed so that assembly and release of the contact tip requires only one turn relative to the gas diffuser.
