    Dear Cherly,

    Here's what the manual says:

    ARC-022 Weld AO scaling limit used 

    Cause: The programmed analog output is beyond the equipment limits.

    Remedy: Check if weld controller is functioning correctly, or powered on.

    I hope you have checked your controller?

    Check to make sure your arc settings are all running the same process. This includes run-in, ramping, arc start and arc end. Also check shock sensor wire shielding , If it is rubbing against any metal it may cause a short.

    Is it happening at the beginning, during or at the end of the weld.

    Most common situation is at the end of the weld, the burnback value change the feedback loop.

    Adjust the burnback if possible. If not, this is assumed mostly as a warning. You can rid of this alarm with the SETUP - ERROR TABLE page and disable the log the alarm.

    Typically, the system try to compensate the weld during the burnback causing a feedback value out of the limits (temporary).
