Are you getting a degenerative circle error? If it is a small circle they can be a pain sometimes, best to test in T2 in that scenario. Do you have any Track sensing or Touch sensing incorperated into the said weld?
To track sens a weld you will need to do a weave sign not a weave circle. It needs the weave to properly track as it is sensing the feedback voltage from the seam. I have seen improper weld tracks cause collisions.
You will need to use a PR for each touch Point. That is were the data is recorded, and correct me if I'm wrong but PR 32 should not be used because that is the temp storage for the search function. Also do you have a wire break and wire trimmer for the power cable assy? Regulating the wire distance as it searches is key to make it successful.
Just make sure you use the correct PR offset were you touched, and I try to touch the 1st surface that will move the most.
