Power frequency AC suspension spot welder machine

This series ofsuspension spot welders are water-cooled suspension spot welders independentlydeveloped by our company based on the European model, with the leadingtechnology across home and abroad.

It is designedwith two structures such as integrated and split type. This series of weldingmachines are of novel structure, high efficiency, secure and reliable, easymaintenance, and fit for various sheets welding. This series of suspension spotwelding machine are consisting of: controller, transformer, water gas circuitand other related parts. The internal controller electrical components used areall high-quality products from home and abroad. The transformer is made withhigh quality imported silicon steel sheets, by integral punching process andintegral vacuum epoxy resin infusion process. Moreover, the insulation class isgreater than grade F. All the pneumatic components on the water gas circuit areSMC imported products, with dual guns and dual gas channels control. As a waterintake filter and a water flow indicator are respectively arranged in thecooling water intake and discharge channels, it can thus effectively preventthe entry of impurities into the cooling water channels, resulting in the blockageand impact of cooling effect. In addition, the water flow indicator is used forthe observation of cooling water flow condition.

The functionssuch as counting and cluster control can be provided at the customer's request.The gas and water circuit board is equipped with the functions of auto-varianceas per settings and drainage of cooling water channel during electrodegrinding. This series of welding machines are of novel structure, highefficiency, secure and reliable, easy maintenance, and fit for various sheetswelding.

The powerfrequency AC models includes: DN3-160KVA, DN3-200KVA, DN3-250KVA, PW-P200KVA,

Product Features

1. For thetransformer, we adopt the optimal design scheme from European technology, anduse the quality silicon steel sheets and new integral punching technology;

2. We use the new advanced technology of integral vacuum epoxy resin pouring.The primary coil, secondary coil and silicon steel sheet are all poured withvacuum epoxy resin;

3. We use a tailored, thick-wall, rectangular, large sectional secondary coilwith internal water cooling;

4. All the insulating materials selected have reached grade F;

5. The welding transformer is of single-phase shell type, with novel design andexcellent performance. The primary coil winding is a disc winding. Anintegrated structure of welder and welding controller is used, with maincircuit emergency stop device;

7. With the dual gas channels, the welder can be equipped with two welding gunsto work alternately. The air pressure of each welding gun is adjustablerespectively. 2 welding specifications are provided for each pair of weldingguns. All pneumatic components have structures easy to disassemble andassemble, thus facilitating repair and replacement;

8. The electronic control gas valve is used for the welding machine, with DC24Vsolenoid valve;

9. The welding process is conducted by a microprocessor in closed-loop control,which ensures the constant welding current under the cases of allowablevariation range of grid voltage and welding load;

10. It has the functions of current step increase control and current linearincrease control, to compensate in steps or linearly the change of weldingcurrent density;

11. Three heat, multi-pulse welding control, especially suitable for plank,cladding plank welding;

12. Intelligent welding programming system;

13. It has the function of error self-inspection, with various abnormal casesimmediately displayed on the programmer LCD screen;

14. It has the function of power-off data storage, to keep the data for up toten years of power-off;

15. Built-in welding spots counting.
