Hi, I have downloaded the latest RobotStudio, and the latest Arcwelding 1 & 2 power pacs, but get an error when trying to use the power pac. (object not set as an instance) or something like that. Had to uninstall everything robot studio related a reinstall studio 2022 in order to continue working on my current projects with arc power pac. Do I need to wait for a 2023.2 version of the power pacs before i can carry on? ---

Hello there, Power Pacs are compatible only with the same version of RobotStudio as themselves. E.g. Arc welding Power Pac 2023.1 will be compatible with RS 2023.1 but not 2023.2. ---

Thanks for the info. Shame the power pacs are not updated at the same time as RS. All good now, as the power pacs are now up to date.
