Abstract
A method of maintaining welding current to compensate for deterioration of a welding contact tip includes: monitoring in real time at least one of welding current and welding voltage during welding production; comparing the at least one of the welding current and the welding voltage to a reference value for a given set of parameters; and adjusting one or more welding parameters in real time to increase energy output in response to the comparison so that consistent energy is consumed across the welding arc, whereby the quality of the welding production is maintained as the welding contact tip is consumed.
Claims18
A method of maintaining welding current to compensate for deterioration of a welding contact tip, the method comprising the steps of:
- monitoring in real time at least one of welding current and welding voltage during welding production throughout the lifespan of the welding contact tip;
- comparing the at least one of the welding current and the welding voltage to a reference value for a given set of parameters;
- and
- adjusting one or more welding parameters in real time to increase energy output in response to the comparison so that consistent energy is consumed across the welding arc as the welding contact tip deteriorates;
- whereby the quality of the welding production is maintained as the welding contact tip is consumed.
