1 、 Profile

     ZX7, selecting  IGBT as  the  main   power  components,  selecting  most  advanced  Full-Bridge Phase-Shift Soft-Switching Technology at home , making waste of switching tube more and more  reduced, makingthe  efficiency  more  and  more  advanced,  and making the quality,performance more and more improved, and so on. Besides, this type of welder has the capacity of thrust control. It is suitable for sheet  welded, and  making freely   weld   from   0   to  630A   come  true. This  type  of  welder  has   the  virtue  of  good welding features, fast reactive speed, small volume, light  weight,  high  efficiency, low waste in zero-load, and so on. So it is replacing the traditional welder step  by  step. Besides, it has been placed in the catalog of high-tech products.

2 、 Principle

3 、 User Guide

      Link DC 0 to 550, press on, the welder begins to work. Firstly, preset the working current according to request. Secondly, change state into working state, The machine will be worked. In the working state, the user could adjust the current to reach the best effect. When the welder is worked in big current for a long time, the temperature of radiator will reach 65 ℃ ,the protected circuits of over-thermal will be worked, making the welder have no output current, the fan will keep on run at this time, making the temperature of radiator reduced, when the temperature is lower than 65 ℃ ,the welder begins to work again. When overvoltage and other abnormal phenomena are taken place on the electrical net, the welder will be protected; fans keep on rotating and have no output voltage. User need restart the welder; it will be keeping on working.

4 、 Attentions

     The welder should be used in the site of good draught, having no rusty gas, having no gas and smut. Pay attention to moistureproof, eliminate the dusts of components in the welder timely. The weight of welder is very light, only 45Kg . User should fetch and put lightly, avoid fall and bump so that reduce unnecessary faults.
