    Automatic Numerical Control MF DC Spot / Projection Welding Machines for Metals

    Automatic Numerical Control MF DC Spot / Projection Welding Machines for Metals


    DESCRIPTION

    Medium frequency inverter spot welding machine is an advanced welding machine with wide application. The welding transformer is in small size but the output energy is large. Three-phase AC will be converted into DC after being rectified. Then the DC will be converted into medium frequency 1000 Hz square wave to be connected to primary welding transformer through the inverter circuit which is composed of IGBT. The MF square wave will become small pulse DC to the electrode for welding work piece through the depressurization and rectifying process in the welding transformer. The inverter will adjust the duty ratio of IGBT through the feedback primary or secondary current so as to achieve constant current of the welding process.



    Compared with the normal AC controller, MF controller has the following advantages:

    1. The current in secondary welding loop is DC. Dramatically reduce the impact to the welding current due to the inductive reactance in secondary loop when conducting welding to the work piece.


    2. The weight of transformer is reduced greatly. It is light and convenient. The weight and size of the MF transformer is only 1/3 of the AC type transformer. Suitable for robot welding system.


    3. Prolong the service life of electrode


    4. Be able to weld material like aluminum, galvanized steel, etc. with good welding performance.


    5. Especially suitable for three-layer plate welding, ultrathin material welding and precision welding.


    6. Less splashes.


    7. Increase control of current and welding quality.

    ***********************************************************************************************

    We can design and manufacture the welding equipment according to your request/drawing, contact us please, we will offer you a suit solution and support you to success.


    FEATURE

    1. Increase the heat input efficiency. The output of welding transformer is DC voltage, without the disturbance of inductance. Pure DC has no defect of zero passage. The efficiency of heat is enhanced dramatically.


    2. Intelligent digital full-closed loop control. The welding control current will be more precise. The adjustment precision and monitoring precision is 20 times higher than the AC system. Be able to protect the inverter and transformer.


    3. Increase the stability of the welding technology. DC welding technology is good and the welding parameters are of wide application. The secondary current could achieve actual constant current. Have better using prospect than AC.


    4. Digital control can better improve the current control and measurement accuracy. The welding time precision is ms which can help you control the welding time at random.


    5. Be able to weld aluminum and galvanized metal with good welding quality.


    6. Especially suitable for welding three-layer metal sheet or very thin material and precision welding requirement.


    7. Precision inverter DC resistance welding. Higher inverter frequency, more accurate control of the current.


    APPLICATION

    Especially suitable for welding metals such as copper, aluminum, nickel, molybdenum, tungsten, manganese, gold, silver and other non-ferrous metals and precious metals precision. Widely applied to welding battery, lighting electric resource automobile, medical apparatus and instruments, photoelectric communication, micro motor as well as requested chip inductor with high temperature enameled round wire/ extra fine wire (minimum size can be 0.02mm),wire rope, metal wire, nickel cup, can cutting wire and welding, CCFL field, fuse, lamp filament.


    COMPETITIVE ADVANTAGE

    1. Professional

    Over 20 years of experience in wire mesh industry and export more than 50 countries. Hwashi is the real professional manufacture.


    2. Product Quality

    The quality of products is the key of enterprise survival. Hwashi is ISO9001:2000 certificated manufacture.


    3. Reasonable Price

    We’ll exact control each producing process to reduce cost for our customers.

    After clients receive the quotation, we’ll show you the rationality of the price and the difference between our products and other supplier’s products.


    4. Delivery Time

    The customer’s need is delivery on time, rather an excuse.

    We’ll make a production plan before producing, and the sales will regularly inform the production schedule and process to the customers.
