Main Features ：

>>Double welding fuselage, adopting the vertical strengthen structure, using high quality thick plates welded together, with to strengthen, the fuselage structure is reasonable and beautiful, and to deal with the stress, and its excellent mechanical properties, is not easy to deformation.

>>Small volume used direct mid-frequency inverter welding power source, transformer output energy, frequency of 1000 hz and the welding transformer transformer rectifier diode can transform electric energy into dc power supply to provide welding is used, thus reducing the production cost very low.

>>Adjustable welding cylinder with large diameter and high pressure cylinder, and is equipped with guide rail, with high efficiency, stable and excellent characteristics of automatic, reliable.

>>Using the intermediate frequency inverter controller output power frequency 1000 hz, the time of millisecond precision; Most programmable 64 sets of welding specification, the more equipped with welding current, solder joints counting functions such as real-time monitoring, easy management, to ensure the quality of welding.

>>Has the function of water shortage, low pressure, real-time monitoring, equipped with sound and light alarm lamp, with red yellow green warning light represent the equipment fault, work and power instructions, maximum extent to ensure the staff's personal safety operation, use safety equipment, welding quality.

>>Adopts double button switches on, the operator between the electrode and is equipped with grating protection, welding machine on both sides of the operation area, equipped with a fence between two cylinders, so as to ensure that by reason of employees improper operation and cause damage to the product or personnel.

Main Parameter：

Design Concept ：

The device is used for the refrigerator compressor sealing terminals and the shell of the compressor, air suction pipe and a compressor housing projections for resistance welding equipment, mainly by the fuselage, medium frequency inverter power supply, special transformers, welding cylinder, upper and lower welding electrode, gas path system, cooling loop, Ann monitoring alarm device.
Customer supplied specification and welding requirements:
1, product specifications: product sheet for medium and low carbon steel, thickness of 3-6mm;
2, the welding strength requirements: terminals and the shell welding firm, meet the destructive experiment (with a 600g hammer percussion and 10.5 to sleep the not leaked);
3, after the welding workpiece requirements: welding terminals and the reference plane height, position with the requirements of the drawings, complete terminal ring, no spatter, glass volume remained intact, can not affect the original electrical properties.
In order to meet the requirements of customers above, our company adopts double cylinder special welding equipment, a cylinder welding wiring column and a cylinder welding suction pipe; parameters are stored in different welding specification, through on the position of the switch from microcomputer control box to obtain the required welding parameters wiring column and a suction tube soldering, so as to achieve the product accurate welding.
