[MW:14739] MMA Welding Electrode Problem

Dear Sir 
I have two plates of SS 304 having thickness of 8mm single V edge prepared for butt weld when I use 2.5mm MMA electrode of SS308-16 on horizontal position it gives very poor profile during root pass and porosity at the start of electrode. when I use electrode of some other brand it gives good root profile. It means there is some problem in electrode and I have to solve the problem. I used 65-70 Ampere for both electrodes. Guide me what is the problem with 1st electrode and how this problem can be removed?
