While waiting for my PT210EXT to arrive (tomorrow!), I've read through the manual, and noticed what appears to be a discrepancy. The specifications indicate that the welder has Advanced Square, Soft Square, and Sawtooth (triangular) waveforms. The manual, however, in discussing the waveforms also includes the Sine waveform.

Is this just because the 210EXT is almost the same as the 255EXT, and they used the same language in the manual? Or do the new 210EXT's now have sine wave capability?
