I have some E 7016 electrodes and need to refresh why I got them. Have looked on the internet and not found anything that clearly explains what they are at least in terms of why one would choose them.
I know they are a low hydrogen rod sort of simular to E 7018 but without the iron powder in the flux. So I am thinking one might use them where you would use E 7018 , but where you have to start and stop a lot. That is they may be a lot easier to restart than E 7018.
While asking about electrodes............ I have not found anything on the internet about Nassau Polaris 18 electrodes. Can find Nassau and Polaris, but nothing about Polaris 18.
