ZX5 Series SCR Arc Welding Rectifier

ZX5 series SCR arc welding rectifier is a kind of DC arc welding power source and can be used in various models of DC manual arc welding. It especially adapts to weld important mild steel, medium steel and low-alloy steel with alkaline mild hydrogen electrode. Compare with rotating DC ones, it features of low noises, efficient, low consumption of materials in the unit capacity and energy saving with annual 5000 degree of electricity save per machine.It is listed one of energy saving products in the 8th generalization of the state ministry and is the most ideal product to replace AX series rotating DC arc welding machine. This series welding machine feature of stable functiona and arc, calm furnace hearth, little falsh and good figuration of welding line. It is convenient in operation for the wireless remote current regulating devices can be equiped under the requirement of the customers. The welding machine equiped with arc ignition current and thrusting current devices and has the function of automatic compensation to voltage fluctuation. No matter hot or cool of the welding machine condition is, it can keep the stable welding current.

ZX5 series welding machine is stable in operation and has a high reputation in customers. ZX5－400 welding machine won the reputation of Beijing Excellent Product and now is the recommended products by China Weld Association. It also won the First Prize in the quality appraisement of Ministry of Mechanical and Electronic Industry and Golden Prize of China 8th Weld Exposition. This series of welding machine was one of the first recommended products by China Electric Industry Association and took the lead in passing the safe attestation in this field of China.

To meet the demand of oilfield, chemical industry, boiler, pressure vessel and mechanical production, ZX5－500 welding machine is developed based on 250、400、630 models. It is completely same with ZX5－500 welding machine in principle, structure, using and operation. The technical datas of ZX5－500 are as follows:

ZX7－400 IGBT Inverter DC Arc Welding Machine

1. Features and usage

Inverter welding power source is one of the most advanced welding resource which is growing in the international market in 80's. This product uses IGBT module as the switch elements. It features of little bulk and light in weight. The efficiency up to 90% and the energy consumption is only 70% of the traditional ones. The output wires up to over 100 meters and it is still has the strong arc. At the same time, the welding current can be regulated at a long distance flexibly and conveniently. The welding machine is reliable and durable for the adoption of the advanced self-pulse control technology and mulriple protection. This kind of machine have the function of self-pulse and automatic compemsation of power grid fluctuation and the welding current can be continuously regulated. It features of stable arc, little flash, efficient and energy saving.

The machine can be used in various models of DC manual arc welding. It especially adapts to weld important mild steel, medium steel and low-alloy steel with alkaline mild hydrogen electrode. It is widely used in the welding works of machinery, shipbuilding, petroleum industry, chemical industry, boiler, pressure vessel and bridge industry.

2. Principle

Principe: AC of the power grid turns to the DC through rectifying--pulse width modulation and inversion--step down by transformer--second time rectifying--stable welding current.

The main composition is rectifying circuit, inverting circuit, pulse width modulating circuit, sample reactive circuit, high-frequency rectifying and filtering circuit and protective circuit.
