You have to use your common sense. What requires documentation? Ask yourself that. Ask yourself why! Your auditor will not know. The auditor will expect you to be able to explain what you have WIs for and what you do NOT have WIs for. And the auditor will probably ask you to explain
why to both do have and do not have.
Let's take soldering - I recently used that as an example in a thread here - you have someone who is soldering who was trained to Mil-Std 2000 at China Lake. Do you need a WI if your job criteria requires some type of training or certification? I doubt it. But then say you hire off the street and have some through hole soldering to do. YHour job requirement is minimal on-the-job training. You would probably want some type of instruction which addresses iron tip temp., characteristics of an 'acceptable' and 'unacceptable' joints (typically visual boundary samples), tip cleaning and other relevant operational features and accept / reject criteria.
If your registrar's auditor is telling you what should be and should not be documented in a WI (or other instruction / procedure) are, you have a very serious gap in understanding the requirements of the standard. I suggest you get some professional help.
Over documentation is very common. It takes thought and common sense to address. Over documentation is costly, confusing, sometimes insulting and detracts from the goal. I always address documentation at the start of any implementation process.

--> Well, as you anticipated, we "passed" with relatively few problems.
--> We had only 7 isolated non-conformities across 5 elements. Details
--> are in the attached file. The auditor said that this was a very
--> good result when compared to other registration audits he has
--> performed. All I can say is I am glad it was successful and Marty
--> said that she was happy to finally win! Once again, thanks for the
--> help. You're advice was extremely important. Especially important,
--> at least in my opinion, was your help in determining where we did
--> not need to document every last thing (by using training, etc.). I
--> think that without this input, we would have spent a lot more time
--> writing things that we did not need and wasted a lot of peoples'
--> time. We were able to get the audit done in a year while we are
--> achieving record sales and profits. Who can argue with that?
