ZX7-400 (380V) PCB with IGBT half-bridge control for riland style mma inverter welder

详情

This product is my company self developed one for miniaturization of pure argon arc welding machine, suitable for all kinds of household type, with miniaturization modular have characteristics, the inversion scheme adopts PWM control technology, constant flow characteristic, current control precision, can be done in 5 a electric arc starting down the success rate reached *9%. Welding current soft stable weld appearance. 1. The transformer core is made of high-tech material base on nanotechnology. 2. The Tri-proof (water, dust and eroding proof) cooling system raised the reliability and duty- cycle of the key components. 3. Having the fan standby-by function. 4. With OCV as high as *0V. Enables the machines to weld acid and basic electrodes. The output cables (*0mm2) will be able to be extended to **0M. 5. With independent adjustment for Hot-Start current. This will solve the problem that different electrode needs different hot-start currents. 6. The duty-cycle is higher than *0% when the temperature of the operation surrounding is around *0 degree .Capable to operate outdoors. 7. The maximum output efficiency is *3%. By using the advanced electro-circuit for power factor compensation, the max power factor could be as high as 0.*5. 8. EMC electro-circuit added to reduce the pollution to the electric network. 9. With digital display of the welding current and remote control for option. *0.VRD function is added to meet the European requirement.
