Spot welding system consists of mechanical devices, electrical devices, control apparatus composed of three parts. Spot welding in order to meet the requirements of welding technology, automation systems - Huashi welding, pressing mechanism (welding clamp) uses a dual-stroke rapid pneumatic actuator, the opening of the welding tongs change by switching the stroke of the control handle, and can be divided into a large open Little Cayman to meet the welding operation requirements. Normal state is open welding tongs short stroke, when the control button to switch to "on" position, pull the handle switch the welding clamp tight while applying pressure to complete a welding current period under the control of the system control after a short trip back to the sheets open. Optional spot welding: welding machine is so widely used. No matter how large shipbuilding enterprises, industrial and mining enterprises and various construction companies welding is an indispensable tool. Welding is a welding materials, power, energy-saving welding equipment to find Huashi welding, the use of a live, especially some small construction unit in order to save the cost of buying cheap welding, Huashi welding - imported brands for use in harsh environments under the construction site can easily lead to electric shock, fire, sealing off the phenomenon would endanger the personal safety and property security. Because the poor quality of welding can also cause "rubbish" project. Huizhou Huashi welding device is a network of CCTV advertising partners, the company's products are patented, Huashi welding, to bring you a safe, secure and reliable products and sincerely look forward to your cooperation. Spot welding principle: the positive and negative poles are using high-temperature electric arc generated in an instant short circuit to melt the solder on welding and the welding material, to achieve the purpose of combining them. Welder's structure is very simple, it means a power transformer, the 2 AC welding 20V to low voltage, high current power supplies, DC also be communication. Welding transformers has its own characteristics, it is having a voltage characteristic of a sharp decline. After ignition electrode voltage drop, the voltage is regulated welding work, in addition to a voltage conversion of 220/380, there are secondary coil voltage tap changing, along with the core to adjust the adjustable welding core general is a high-power transformer, the Department made use of the principle of inductance, inductance in the switched on or off voltage change will have a huge, positive and negative poles of a high-pressure arc short circuit in an instant to melt the welding electrodes solder. to achieve the purpose of combining them. Applying a voltage between the electrode and the workpiece, or by contact with ignition stroke Sassafras arc welding with arc energy and heat melting the base metal. Huashi welding small welding machines, internal coating pan ear specialist welding machine supplied by Huizhou City Huashi Welding Equipment Co. Huashi welding small welding machines, internal coating pan ear specialist welding machine Huizhou City Huashi Welding Equipment Co., Ltd.
