One millimeter thick iron direct current welding machine welding 3.2 electrode, need much current?
It's broken at one o'clock
1, 3.2 electrode obviously thicker; should use less than 2.5 diameter of small welding rod;2 、 welding electrode and current matching empirical parametersWelding rod diameter 1.6, 2, 2.5, 3.2, 4, 5, 5.8Current (A) ranged from 25~4040 to 6050~80100 to 130160~210200 to 270260~300This is the experience of welding current, welding, horizontal welding, overhead welding welding current should be smaller than usual 10% ~ 20%.Exp is the confirmation at the time of the experiment. Therefore, before the formal welding, the welding sample should be taken, and the welding current should be obtained to get a solid and beautiful bead.
It will break a bit! It is recommended that you switch to CO2 shielded welding or use resistance welding (designed to allow).
