I have a MMA welding electrode of SS 308L Dia. 2.6mm. when half of
the electrode is consumed it get red hot, and it gives porosity in the
weld metal what could be the reason i.e. is it a welding problem or
there is a problem in the electrode???
if this problem is due to electrode then what can be the reasons and
rectifications???
