When welding, for example, 3.2 of the electrode should choose how much current
Empirical formula: welding electrode current = 30~55 times of electrode diameterSelect the base material thickness
Personal summary of 4 times to the electrode diameter, good to be divided into vertical welding and welding is different, the package has recommended the use of current electrode. 3.2 of the welding rod is between 90-120A and standing 90-100.
The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
