Refrigerating Condenser Wire Welding Machine Rated Bleed Pressure High Reliability

The welding process is as follows,
1) When starting working, the welding fixture will firstly enter into the automatic wire feeding area to complete the bottom layer automatic wire feeding;
 
2) Then the fixture will move back to the manual loading area, the operator needs to put the S-shaped copper tube onto the bottom layer wire;
 
3) Afterwards, the fixture will move to the automatic wire feeding area automatically to complete the upper layer automatic wire feeding;
 
4) Then, the fixture will move forward to enter into welding area to complete welding process.
 
5) After welding, the fixture will move back to the unloading area. The fixture will be loosening through vibration.
 
6) At last, the fixture will return to the loading area for the operator to take out the work piece and start the next welding process.
 
In order to improve the efficiency, the machine is designed with both sides feeding rack. The welding process for both sides is the same which will take turn to work.
 
Features
1. Main Body:Because of the dense and horizontal wire rod, the integrated reinforced gantry type of main body is designed. Adopt the vertical stress main body. This machine is made of good quality of thicken steel plate to ensure the intensity and stability of the main body. The machine is equipped with slide guide to provide stress supporting point and working platform for other actions. In order to put two sets of welding fixtures on the machine, the effective welding width is 1300mm while the welding length is 1000mm.
2. Power Source: Adopt medium frequency inverter welding source. Duty cycle rate reaches 50%. The three-phase power supply is under rectifying through a special inverter and converted to 1000Hz AC voltage and then be transmitted to a medium frequency transformer to be rectified so as to provide DC welding current. Compare with general AC pulse power supply, this kind of power source could be fast and precisely adjusted. Small impact to the power grid and lower requirement for the power grid compare with the single-phase welder of the same capacity.
3. Row Welding Structure: 6 sets of welding electrodes are installed on the beam and equipped with slide guide that could move horizontally. It is convenient to adjust the distance of welding spot so it is suitable for welding the work pieces with different pinch. The welding program of row welding electrode is flexible and various kinds of welding programs are available. So you could choose to weld from the middle to the sides or from the sides to the middle or single welding. Truly achieve the stable, reliable and good consistency of welding effect.
4. Cooling System: Resistance welder will generate lots of heat during the process of welding. The source of heat may be from: the welding of electrode and work piece or the working of components like silicon controlled and welding transformer. In order to protect the working life of components and control the softening temperature of welding electrode to ensure the reliability of welding, it is designed to adopt the cooling water cycle to take away the heat. The air-cooled type of cooling water is adopted. Through the refrigerating system of cooling-water machine, the temperature of water is forced to cool down to the preset temperature. The purpose of cooling water cycle is achieved through the water pump of cooling-water machine and water storage box.
