IGBT ZX7-ST arc MMA Series IGBT welder welding machine thyristor Argon gas shielded
ISO9001 CCC and CE certification

IGBT ZX7-ST  Series IGBT arc welder           
For power construction, petrochemical construction, pressure vessel, shipbuilding and other industries and production enterprises, can be used as  carbon arc gouging power           
Features            
1.  One machine to be completed by welding, manual arc welding two processes            
2.  Easy arc, arc stability, weld pool and easy control            
3.  Welding with self-locking / non-self-locking            
4.  Digital meter head, the welding pre-current can be accurately             
5.  High duty cycle,            
6.  Soft switch transform, high efficiency machine            
7.  Power factor highly           
8.  High switching frequency, small size, light weight ,tungsten electrode protect           
9.  Length can be adjusted at any time           
10. 500A welding machine over both carbon arc gouging            
11. Suitable sheet: carbon steel, stainless steel            
welding.
Excellent dynamic characters, arc stability, welding forming good.
3.This machine can perform to voltage fluctuation, so the machine automatically compensates for the cold and hot state that they can remain stable current.
4.This machine is replaced ZX5 series and BX series welding machine functions.
5.Saving energy, saving more than 50% than BX series.
Use cost greatly reduced:
1, BX1 series effective power equivalent of this series dc welder effective power of 70%.
2, The BX1 series the machine efficiency only this series dc welder efficiency of 50%.
3, Managing electric energy more than 50%, quarterly can save a welder.
