AC Spot Welder
AC SPOT WELDER
AC spot (convex) welding machine is mainly suitable for welding of low carbon steel, stainless steel, plated plate and some non-ferrous metals, and can realize the projection welding of plate to plate, wire mesh, plate to projection welding nut, stud. It is an indispensable equipment for welding parts in hardware, sheet metal, home appliances, machinery, metal cabinets and other fields. There is no doubt about the quality of welding. New structure design, careful consideration of operation and maintenance and environmental protection.
直接式加压机构，随动性能好，焊接速度快 ■ Direct pressure mechanism, good follow-up performance, fast welding speed
The guide is made of a special material with low friction, and the solenoid valve is directly connected to the cylinder, which speeds up the reaction speed of the action, increases the speed of the dot, and reduces the loss of air flow.
使用寿命长、噪音小 ■ Long service life and low noise
Equipped with a pressure speed adjustment function, the speed of the pressure head can be adjusted arbitrarily, which alleviates the impact when pressing the object to be welded. Equipped with ascending buffer adjustment function, which can adjust the ascending buffer speed arbitrarily; reducing mechanical impact improves the service life of the cylinder block, and also reduces noise.
安全、使用方便 ■ Safe and easy to use
The high-performance air system filter cup is equipped with a cover to prevent the debris from splashing when the cup is broken, and it can also protect the impact from external impact. The cups and shields are removable and easy to overhaul.
采用节水型强制冷切方式 ■ Using water-saving strong refrigeration cutting method
Circulating cooling water is used to avoid waste of water and greatly reduce the amount of cooling water.
高牢固强度的机体结构 ■ High solid strength structure
With rigidity against impact and vibration, it can prevent the electrode tip from sliding during pressurization and realize stable welding.
上部绝缘简单实用 ■ Simple and practical upper insulation
The secondary conductor adopts the upper insulation method, which can avoid the adhesion of iron filings or short circuit accidents in the insulation parts that are easy to occur when the lower seat is installed with welding tools.
主回路采用大功率SCR无触点开关 ■ The main circuit adopts high-power SCR non-contact switch
The main circuit uses water-cooled high-power thyristor elements, which have strong, stable output power and strong reliability.
高导电性、电力损耗低 ■ High conductivity and low power loss
In the secondary current loop, the secondary output on the main transformer uses multilayer high-toughness, high-conductivity copper flexible ribbons and V-shaped connections; the service life is greatly improved, and the lower secondary output uses an integrated direct connection mechanism to reduce power loss. .
