What do you mean by "WS.TIG.ZX7." on argon arc welding machine? What are the characteristics of each?
ZX7-*** inverter direct current welder:Z denotes DC (arc welding rectifier)X indicates the drop characteristic (the instant arc voltage is about 70 volts, the arc is successful and the welding voltage drops rapidly to about 30 volts.)7 represents inverter type, including third generation inversion of MOS field effect tube, IGBT (IGBT single tube, IGBT module), fourth generation inverter.
WS and "TIG" are the meaning of "argon arc welding". The domestic use of WS means "TIG" in foreign countries, and "ZX7" means "hand arc welding".
WS TIG is tungsten argon arc welding machine. ZX7 belongs to inverter type DC welding machine.W: the first letter of tungsten tungsten arc welding tungsten. Representative: TIG welding machine.S: hand welding, including welding rod, hand arc welding.TIG: tungsten inert gas arc welding, such as tungsten arc welding, tungsten arc welding, etc.. Helium is more expensive, usually only by a certain gas mixture ratio of argon gas welding, so TIG usually refers to argon tungsten arc welding.ZX7:Z: arc welding rectifier, the first letter of the whole word, representing the DC (arc welding machine).X: down characteristic output power supply. Suitable for hand welding, such as welding rod, hand arc welding, TIG welding. Constant current characteristic. The welding arc is sensitive to the welding quality.7: inverter type.
