What is the best welding machine brand? Where can I get the professional manufacturers for ZX7 series inverter arc welding machines? PETROL STEEL CO., LTD is the professional suppliers of ZX7 series inverter DC mine arc welding machine (IGBT dual module) and can supply 7*24hours free service.
How to solve the problem of overheat protection on ZX7-315 electric welding machine? The overheating protection bai of the electric welding machine has two kinds of real protection and fake protection. If it is du protection, check the fan, if the fan is operating normally, check whether the power device is normal, if all are normal, it means that the welding machine is short-circuited, just replace the short-circuited part. If it is false protection, just change a temperature relay. The temperature rise of the welding machine during load welding should not exceed 60 degrees for class A and 80 degrees for class B, othERWise, it should be shut down to cool down before welding. During welding, it is not allowed to adjust the current. The adjustment handle must be used when the welding is stopped, and it must not be too fast or too strong to avoid damage to the regulator.
What are the advantages of the ZX7-500I inverter DC arc welder? Using IGBT power module devices and advanced electronic circuits, it saves more than 1/3 of the electricity of traditional welding machines. It is a new type of high-efficiency and energy-saving mechatronics product. It has the characteristics of fast dynamic response, stable welding arc, strong power output capability, precise adjustment, high efficiency, low no-load loss, complete protection function, and higher reliability.
What is the welding adaptability of the ZX7 series inverter arc welding machine? The principle, function, and use method of ZX7 series inverter DC arc welding machine. 1. Significantly reduced copper and iron loss improved the overall efficiency of the welder and significant energy-saving effect, and the outstanding adaptability to power waving; 2. Digital display meter, welding current can be accurately preset; 3. It has the characteristics of easy arc ignition, small splash, stable current, and good forming. 4. With a variety of protection functions, temperature protection, overcurrent protection, short circuit protection, etc.; inverter frequency is 20KHz, small size, lightweight; 5. With automatic voltage fluctuation compensation function, strong resistance to grid fluctuations, stable and reliable welding current; 6. The arc thrust can be adjusted with the length of the welding cable to achieve long-distance welding; 7.Can be widely used in the welding of various acid and alkali electrodes.
The application of the new ZX7-500 series DC inverter arc welding machine in coal mine industry. With the upgrading of coal mine voltage, in view of the inconvenience of the original 380/660 V electric welding machine, a new type of ZX7 series DC inverter arc welding machine was designed. Compared with the electric welding machine used by old coal mine enterprises, it has the advantages of high practicability, safety, investment saving, light and flexible equipment, high stability of welding quality, small spatter, and low energy consumption of welding machines. It has been used in many coal mines at present, which greatly improve the labor efficiency of the user unit, reduce the equipment investment, and get the approval of the user unit.
Is the inverter DC welding machine ZX7 temperature relay normally open or normally closed? If it is over-temperature protection, it is normally closed, if it is used to control the fan, it is normally open.
The normally closed type is used more, the normally open type is used less.
