Re: [MW:14393] MMA welding Electrode Gets red hot

The electrode dia. must be 2.5mm and not 2.6mm !

What current you are using ? You might be using higher amperage than the recommended parameters by the consumable manufacturer or your WPS.

Generaaly SS and Inconel 2.5, 3.2 mm dia electrodes have a tendency to get red hot while welding at higher amperages.

This also depends on the coating factor of the electrodes.

Also check the calibration of your welding power source.

 

If the problem of porosity is still there then try with another brand.

Subject: [MW:14386] MMA welding Electrode Gets red hot

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???
