1 、 Introduction

     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 0V to 550V,press the button then the welder begins to work. Preset the working current according to the illuminate then it will go into the working state .The user should adjust the current during the process of working in order to gain a good effect. The temperature of the radiator will reach 65 ℃ if the welder works in a big current for a long time .Then the protected circuits will work at this moment to ensure the welding apparatus have no output current and at the same time fans will keep on running to down the temperature .When the temperature get lower below 65 ℃ ,the welding apparatus will works again and you just need restart the instrument. If the over-­­ ­voltage or other abnormal phenomena happen, the welding apparatus will get into the condition of protection.

4 、 Attentions

    The welder should be used in drying station and have to make sure there is no rusty gas, gas and smut. And we should also pay more attention to moistureproof, so we'd better clean the dusts of its elements timely. Owing to its light weight of only 45Kg ,users not only can fetch easily but also can avoid fall and bump .
