HWASHI C Type / X Type Hanging Portable Spot Welding Machine
Suspension portable type spot welding machine consist of welding gun, welding machine transformer, welding machine controller, water cooling system, pneumatic pressure system, the suspension device, etc. Processing method adopts work piece fixed and moving welding gun.
Features
1. Compact structure. Convenient maintenance. Small in size and light in weight. Greatly reduce the labor intensity and largely saves the energy consumption.
2. Electrode arm is made of high quality chromium zirconium copper alloy, ensuring the stability of welding performance, service life of welding machine and strength of electrode arm.
3. Large diameter of gas path system, with imported pneumatic components. Makes the welding gun move fast and improve production efficiency.
4. When welding, heating time is short, heat concentration, no arc, no sparks, no welding slag, no fusion welding accumulation and no deformation. Beautiful appearance. Good quality.
5. Change thyristor conduction angle for heat regulation by welding machine controller. Make it easy to achieve mechanization and automation. So can match with the industrial robots for fully automated welding operation.
Application
Mainly used for welding of general fixed welding machine which cannot or inconvenient for welding low carbon steel, low alloy steel, stainless steel, coated steel, plates and bars material. Widely used in automobile, commercial sheet metal, security doors, cabinets, household appliances, and other industries.
Power Supply System
This machine is equipped with medium frequency power supply system with 1000A inverter device, 90KVA capacity and 50% duty cycle rate. The maximum short circuit current is 25KA.
Medium frequency inverter spot welder is advanced welding equipment. The three-phase power supply, through rectified by a special inverter, is converted into 1000Hz AC voltage and then is transmitted to a medium frequency transformer. The current is rectified in order to supply DC welding current. The advantage is that it helps to greatly reduce the energy of iron core material, as the frequency of welding transformer is promoted from 50/60Hz of mains supply to 1000Hz. Besides, the commutation diode of subloop of transformer could transform the electric energy into DC power which is used to provide power for welding. Under such circumstance, the inductance coefficient of subloop could be improved dramatically and the production cost could be minimized because the inductance coefficient is an important factor that results in energy loss but could almost be ignored in DC welding circuit.
