Abstract
A welding-type system includes a power supply configured to control preheating of an electrode wire. A controller is configured to receive a plurality of power values corresponding to a power output of the power supply and calculate an arc power value corresponding to an arc condition at the preheated electrode wire based on a rate of change of the plurality of power values. A target power output value is determined based on the calculated arc power value, and the power output is adjusted based on the determined target power value.
