There is lots of choices for lubes and solvents in welding so do check if it is safe to weld around.
Anything with chlorine is out. Some cutting lubes used to have chlorine in them, only recently have they changed. Brake cleaner is a big no no.
They all perform well under heat, until they are exposed to welding temps and become toxic vapours.
Any lube with a cleaning action should be looked at. Most are ok but some use chlorine and other nasties, that work well at thier designed temp, but not at ours.
Wd40 and firearm lube is generally ok though. But if you use anything, know what it does when you weld it.
