1 、 Introduction

    ZX7, choosing the advanced IGBT technology as the main power device and adopting the most advanced Full-Bridge Phase-Shift Soft-Switching technology to improve the quality of our products. As a result ,it has the functions as follows :reducing the waste of switching- tube , improving the efficiency of our products, thrust control. It is suitable for sheet welded and can make freely weld from 0A to 630A .This kind of welding apparatus has many virtues as follows: quickly reflected speed ,small volume ,light weight, high efficiency, low waste in zero-load and so on. It has been placed in the catalog of high-tech products and which is replacing the traditional welder step by step.

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 .
