Which Stainless Bars for 4 Link

All gold weld is the best color because of the temp. its at a good cooling / welding speed and its best to back perge it too

we didnt get to back purge in school but the teacher said that was the way they welded all of the really trick stuff i but it would cost a mint in time and money to set up for back purging just think of all the gass youd waste

WHEN I GOT CERTIFIED IN STAINLESS, TITANIUM, ALUMINUM ETC. I HAD TO BACK PURGE ALL MY WORK SO ITS A PERFECT BEAD FRONT TO BACK..
