Detail of Dual pulse spot welder machinery equipment, MINGDA md-2005 point welding machine

MD-2005 series Spot Welder Machine battery assembly welding power source is used the latest welding technology "polarity switching" welding way, so far it is the advanced level high performance inverter resistance welding machine, it is special designed for the production of high-end mobile phone batteries, power battery, digital battery, mobile power battery, nickel metal hydride, nickel cadmium cell.


MD-2005 series inverter DC resistance welding power source is a new power which adopt the IGBT inverter technology, microcomputer control technology and modern power electronic technology development. Since using AC, DC, AC, DC transform technique, time control have reached millisecond level precision, control response and control accuracy greatly improved; Dc output improve welding manufacturability significantly; Inverter technology still make equipment to small, energy saving and high efficiency and a series of advantages; Microcontroller (MCU) and electronic technology using make the equipment have excellent functions of modern equipment, including digital control, monitoring, fault diagnosis and protection, data transmission, equipment, the function is all ready, agile and convenient, wide adaptability.


The battery cell spot welder use microcomputer control, blue LCD display, keyboard control of welding parameters, easy to operate. This machine at present has become the classic welding equipment. the lithium battery, nickel chromium nickel-metal hydride batteries, button batteries, cylindrical sexual battery manufacturer.

Feature of Dual pulse spot welder machinery equipment

1.High speed and high precision micro processor (MCU) control, provide highly stable repeat welding.

2.High speed welding: quick start with high speed polarity switch reduces the temperature effect so that keep the welding surface clean and beauty.

3.Polarity switching: inhibition asymmetric effect makes the two point weld strength uniform and extend the electrode life.

4.DC output: welding current is pulsating direct current (waveness is small), no AC zero discontinuous heating workpiece shortcomings, heat concentration and improve the welding thermal efficiency, it is especially suitable for welding the non-ferrous metal materials and some difficult welding materials, welding process is stable, welding quality improved significantly. At the same time, the electrode life get extended.

5.Fast response. Power on time control cycle is 1 ms , 20 times than 20ms of common AC battery welder

6.Blue 19264 LCD screen display, graphical display the current working status, friendly working interface, welding pulse graphic display function to improve the convenience debugging observation.

7.Compatible with mechanical and pneumatic welding head.

8.Double pulse reduce welding spatter, effectively improve the welding quality.

9.Two different welding methods (1) general spot welding; (2) continuous welding.

10.The built-in welding counter, can do all its solder joints.

11.Data storage using EEPROM, no battery life problem, each operation  all returned to welding procedure of the last use .

12.Compatible have welding pressure switch of the welding head and no welding pressure switch of the welding head.

13. Preloading time and holding pressure time from 0 to 2.55 seconds continuous adjustable.

14.Discharge switch can use mechanical or photoelectric switch.

Application of Dual pulse spot welder machinery equipment


Operation of Dual pulse  spot welder machinery equipment

A. Height adjustment of Welding needles : loosing the height adjustment screw with a

wrench. Then adjust or replace the length of needles exposed below the electrode(usually, it
is about 15mm. It is easy to deform if it is too long) finally, tightening the screws


B. width adjustment of Electrode (needles) : loosing the width adjusting screw with a

wrench, then adjust two electrodes so that two needles to appropriate distance. Last,
tightening the screws.


C.Test: test whether there is coke on the needles or not., if so. you need to clear it with a

file or abrasive paper. then using the right foot press pedals . When its head drop, stare the
welding needles until the needle is on the welding point


D. Power: put plug into a 220V power socket, and turn on the power switch, indicator

flashing, the welder is work. If working indicator does not shine or shine without flashing.
turning off the power then turn on again.


E. In order to ensure good quality of welding, you should often adjust needles and keep it in

a good condition.  

A. Keep the needle and electrode from contacting . Or it would short circuit and does not
B. the current can not be adjusted too large. Generally, 0.1mm welding material can be
welded when the current at 20-30
C. High pressure inside the chassis . Do not open it.
