Product Description
？ Quick Details Place of Origin: Zhejiang, China (Mainland) Brand Name: Jiaxiao Model Number: FN-75KVA Packaging & Delivery Packaging Details:wooden case Delivery Detail:20 days Specifications ？ model No: FN-100 KVA duty cycle: 50% Rated primary current:200A Max. welding thickness(mm): 1.0+1.0 ？ FN—75seam welding machine is single-phase of？ AC 380V？ 50HZ seam welding machine,It is main to welding the mild steel, stainless steel pail,tube,box and without leak thick wall vessel, which is specialized designed and manufactured for thick plate seam welding. ？ FN-75 seam welding machine is main made of three parts, namely host, controller, transmission structure. ？it is made of case, welding transformer, controlled silicon installation board, gas circuit pressure system, cooling water system, welding wheel group etc. ？(1)Case is welding of steel plate. (2)Welding transformer adopt the secondary water-cooling. (3)Controlled silicon installation board is made of water-cooling controlled silicon and resistance capacitance protect wire. (4)Gas circuit pressurizing system is made of pressure regulating valve, gas water separator, pressure cylinder, electromagnetic gas valve, pipeline. (5)The transformer ,controlled silicon, up and down electric conduction, cool off of the welding wheel are offered by waterway. (6)Welding wheel team is made of welding wheel and wheel frame, between the transmission shaft and frame using the electric conduction to smoothed.？ ？ Transmission organization is due to the transducer and speed-down electric motor through chain wheel transmission organization to driving the up welding wheel whirl, ？when the pressure wheel lower for welding, that is, down welding wheel whirling through the up welding wheel and workpiece driving. By set up FC51 transducer can change the turning direction of welding wheel. The speed of welding can adjust by panel adjust of FC51 ？ Seam welding machine using the footswitch to operate the welder action. When the first step lower the footswitch, footswitch signal will be sent to the welding controller, connected to the solenoid valve, the electrode dropping , idler wheel pin？ welding pieces, prepare to welding. When the second step lower the footswitch, footswitch signal will be sent to the welding controller again,At this point, controller connected to the electrical transmission, seam welding wheel start to rotating, and connected to welding current at the same time, welding process beginning . When the welding will come to an end, lower the footswitch again, the third footswitch signal will be sent to the welding controller, controller will disconnect the drive motor and disconnect the welding current, delay after a period of time, disconnect the electromagnetic valve, up welding wheel will be uplift, all welding cycle is over. Welder waiting for the next welding cycle.
