Shanghai Dayang WSE5-315 wsem and Shenzhen Jiashi of square wave AC DC inverter argon arc welding of WSE315, the function is the same? Can it be completely replaced? If welding, auto cylinder and cylinder head can be used? Why is the former heavy 195KG and the latter only 38KG?
Ask I think welding non-ferrous metals 315 small.
Alternative inverter welding machine is a silicon controlled rectifier, and it is higher than scr. Inverter welding machine is more energy saving, less volume, lighter weight and higher weld quality than SCR welder. However, because the main components of domestic inverter welding machine are not mature, the performance of domestic inverter welding machine is not very stable now, and there is still a big market for SCR welding machine! The largest welding inverter manufacturers Tangshan Matsushita, Shandong sun, Beijing times. Shenzhen Christie's 250 below the small welding machine performance is very good!
Difference between SCR and invert argon arc welding1, SCR rectifier is AC rectifier 50HZ into DC output, by changing the thyristor conduction angle to change the size of the output, the output waveform is not smooth, so the welding effect is not very good, the arc and other control functions slightly worse.Inverter argon arc welding machine is AC rectifier, through IGBT inverter, the intermediate frequency transformer step-down, after two times the rectified output, output waveform, change the output by the pulse width modulation control of IGBT inverter conduction time size. The arc striking and thrust current are easy to control.2 、 SCR rectifier welding machine is bulky, bulky, inconvenient to carry and move; and inverter argon arc welding machine inverter frequency as high as 20-30KHZ, so the transformer is small, light weight, easy to handle.3, inverter welding power inverter than the argon arc welding machine power saving of about 30%.4 、 inverter arc welding machine control and main circuit is relatively simple, high reliability, little trouble, easy maintenance.
