China leading manufacturers and suppliers of Medical Waste Treatment ,Medical Waste Solutions, and we are specialize in Medical Waste Sterilizer,Medical Hazardous Waste Disposal, etc. Medical Waste Microwave Disposal Equipment Medical Waste Treatment,Medical Waste Solutions,Medical Waste Sterilizer,Medical Hazardous Waste Disposal Henan Liying Environmental Science and Technology Co., Ltd. , https://www.disposingmedicalwaste.com
Our company produces the ZX7 series contra variant concurrent manual arc welding machine, is one kind of high efficiency energy conservation direct current welding power source, uses the IGBT power switch component to pass advanced PWM 20KHz pulse-duration modulation technology 50Hz power frequency inversion 20KHz high frequency, again carries on the voltage dropping resistor rectification, the output may supply the welding the high efficiency direct-current power supply.
Features:
1.simple electric circuit,strong anti-jamming ability.
2.Arc force can be adjusted according to the length of the welding cable,long-distance welding is available..
3.Striking current can be adjusted,applicable for striking arc or workpiece with different platethickness.
4.digital display ammeter,the welding current can be preset accuragely before welding.
5Applicable for the welding of various electrodes including Φ2-Φ6 acidic,refractory steel electrode and etc.
6.Applicable for the welding of stainless steel,carbon steel,alloy steel and etc.
7.The fuction of carbon arc air gouging can be also available for welding machine above 500A.
8.High frequency inversion,small volume,light weight,energy-saving.
