Abstract

A method and apparatus for welding uses a power circuit and a controller connected to the power circuit. The controller included a welding program having a limited term. The program may be part of a system, or a stand alone program. The controller has a data port and the welding program and/or an authorization is received by the controller on the data port in one embodiment. The welding program includes a limited time module, a limited time in use module, a limited arc start module, a controlled short circuit program, and/or a pulse program in various embodiments. A second welding program, without a limited term module, may be provided.
