Re: [MW:14783] Tapered burning of MMA electrode

Thank you very much for your advice. 
I have tried to compare the welding profile for both types of electrodes i.e center out and center ok electrodes but both electrodes give the same profile. 
Can it be a problem of magnetic arc blow because I felt my electrodes posses some magnetic response?

Dear Ahmed,
There seems to be the manufacturing problem.
Please check the concentricity of the electrodes. Such problem occurs when the coating and the core rod are not concentric.
Warm regards
