Hi
There would be more concentricity in the electrode , which will give red hot condition.
You may lookout the electrode, there should be nearly equal melting of wire and flux,
If there is deep cup and cone formation of the electrode , may also cause of the red hot condition, which need to be adjusted by the flux ingredients.
May be you check with R&D Engineers from the consumable suppliers.

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???
