An arc welder produces a weave pattern between workpieces. Each weld run comprises a center portion including a joining region between the workpieces and edge regions spaced apart from the joining region. The welder includes a power source that provides a welding waveform to a welding electrode to generate an arc to achieve a desired heat for welding, a welding torch, and an oscillator for oscillating the torch between the welding edge regions. A controller causes the power source to operate in a first mode utilizing a first waveform during welding within the joining region, and in a second mode using a second waveform, having a greater positive component than the first waveform, during welding within the edge regions. The controller determines a stickout value based on the first waveformbut not the second waveform, and performs seam tracking based the second waveform but not the first waveform.
