Hello Mark, I could be mistaken, but as I have understood this particular scenario, the copper colored coating on carbon steel wires of various grades and strengths is there to inhibit rust, additionally, I can't verify this, but I am thinking that ER70S-2 is an uncoated grade of carbon steel wire. Stainless wires and other solid wires that don't readily rust do not require this additional "coating" and do not have a "lube". This has been my understanding, however I am more than willing to be corrected if I have this wrong. My $.02. Best regards, Allan
thanks again for all the input, I guess my main consern is that the lube does not introduce any contaminents like hydrogen or some other nasty stuff
Do the majority of you gents. use the stuff?
Allan,
We both could be in for corrective information on this, because I have the same opinion of the "coated" solid wire. It is a rust inhibitor rather than a lube.

I think you are on the right track with it being a rust inhibitor rather than a lube. It may in the end also lube the wire. As you have mentioned about wire being exposed for extended periods of time, this "rust inhibitor" will collect dust. This is where I have seen the lube utilized the most, as the dust in the air sticks to the "inhibitor" resulting in binding in the liner. Of course this will vary from shop to shop as well as location to location within said shop.
