    Help - Hack Optima300 pulser to work on XMT304?

    I just replaced my grenade XMT300 CC/CV with an XMT 304 CC/CV and was disappointed to find my Optima pulse unit will not work on the "new" machine. Has anyone hacked the older pulse unit to work on the newer machines? Based on the pinouts of the 14 pin connector there can't be much to doing this. I tried running the spoolgun on aluminum and quickly realized that without the pulser I cannot get the penetration of spray transfer without killing the ability to weld out of position.

    Thank you

    Have you tried the Miller forums? If it's possible at all, I bet someone on there will have done it before. Remember this is all digital, it's not just a couple of potentiometers... so if it's not compatible, it's not compatible, full stop.

    Alternatively, if you were not able to mod the old optima, and would like to get a new one, a member here (chopper) was selling 3 of them. I think he has one left for $300.
