Abstract
A control parameter ramp profile that enables control parameters to be modified in a non-linear manner, such that as a temperature set point of a tool or a weld is approached, the control parameter ramp profile enables the temperature set point to be approached in a manner that prevents temperature overshoot and therefore creating a better weld along the length thereof, wherein the control parameter ramp profile includes but is not limited to proportional, exponential or an S-curve waveform.
