Just out of curiosity what does the alcohol do?? Is it just a clean lubrication? I preclean weld areas with acetone at the moment, will that work the same?

Hi Nate,
We've tried a number of "cleaning lubricants" with the aluminum surface thing, over the decades. I won't list them here ...
But..... 91% isopropyl is very ideal for our uses - and as the two PhD research chemists who have popped in have told us, " Excellent solvent, Mr. White: Clean. Cheap. Available. Non-toxic."

And for us, "the lubricity is ideal."


(psst: "chlorinated hydrocarbons," acetone being one popular type, actually create phosgene gas when wet within a high-frequency electric field (tig welding aluminum, anyone??). For those who do not know about WW1 gas attacks, thousands upon thousands of troops were gassed with "mustard gas" aka "phosgene gas" - which either killed them outright or rendered them completely helpless and permanently injured.



Acetone is not recommended near any type of electric welding, no way, no how....!!!!

--- that is all ---
