(1)Whether EWLa-1.5 or, EWCe-2 are hygroscopic in nature with respect to EWTh-2 ? (Our concern-whether EWLa-1.5 or EWCe-2 absorbs moisture on long time exposure and can cause hydrogen induced cracking on weldment?)

(2)Is there any major health hazard issue associated with EWLa-1.5 or, EWCe-2 electrode with respect to EWTh-2? If yes, what are the hazards?(note- we are trying to explore EWLa-1.5 or EWCe-2 as a substitute of conventional EWTh-2).

(3)Is there any consumption comparison data between EWLa-1.5 electrode vs EWCe-2 vs EWTh-2? If yes, kindly provide details.
