380V argon arc welding machine output current 100A, what is the input current?
Just count it in a simple way380V divided by 60 (maximum rated voltage) =6.4 timesIt is assumed that the voltage and the current are linear100A divided by 6.4 times =15.6AThe current should be about 15A
1 argon arc welding 100A corresponding rated voltage 100*0.04+10=14 Volts2, input current =14*100/ efficiency / power factor /380/1.732, inverter welding efficiency is generally 0.85, power factor is generally 0.9~0.95, conservative by 0.9, then input current =14*100/0.85/0.9/380/1.732, about 2.78A
Input current =14*100/ efficiency / power factor /380/1.732, inverter welding efficiency is generally 0.85, power factor is generally 0.9~0.95, conservative by 0.9, then input current =14*100/0.85/0.9/380/1.732, about 2.78AArgon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
