Product Description

 Capacitive discharge spot welders at low price for high quality

Overview of Capacitive Discharge Battery Spot Welder

The latest spot welder introduced a high-frequency resistance spot welding for high-end needs of clients this spot welder is microcomputer control and AC-DC resistance sticks, single phase or dual pulse, capacitive discharge or transform discharged spot welding; the spot welders have wide scope in application at KEEPLEADER™, under examples for reference

01: All kind of steel lithium battery assembly

02: Aluminum lithium battery assembly, aluminum lithium-ion battery composite film of Nickel and aluminum welding

03: Nickel plate and Nickel plate connection, Nickel plate and the battery connection

04: Lithium-ion batteries and Nickel plate copper connection

05: All kinds of button batteries and Nickel plate welding

06: welding thin button cells will not have depression, yellow, black phenomenon

07: Ni-MH battery assembly

08: All the old batteries repeat the spot

09: Various hardware components of the welding

10: Foam Nickel, then precision hardware side access

Single and dual pulse versions

This spot welder has fine spot welder power sources allow you the versatility to take on welding from the large all the way into the micro-scale! KEEPLEADER™ spot welder gives good repeatability by displaying the exact energy readout of each weld, purchase a hand weld tool or weld heads to meet your welding requirements

The features of Capacitive Discharge Battery Spot Welder at KEEPLEADER™

01: inexpensive, capacitive discharge, power source single or dual pulse versions available

02: Adjustable weld energy/power, dual pulse systems have adjustment for energy for both pulses, in addition, the dual-pulse feature can be turned off.

03: weld energy indication

04: optional pen, battery tab and manual or pneumatic plug-in weld heads

05: standard foot switch

06: microcomputer control, visible and stable output, dual-pulse welding that can do pre-welding, pre-solder oxide removal, remove debris, reducing the spark, continued welding to ensure a solid solder joint appearance, no black, spot size of the uniform burr, does not affect the appearance of the welding appearance

07: with the traditional exchange pulse, capacitive discharge spot welder, welding time is very short on the intrinsic properties of the batteries had no effect, does not affect the battery internal resistance, change does not affect the voltage and capacity, but not to cell performance impact

After completion of the weld surface of the battery is more clean, burr is small, not yellow, and not black

08: the microcomputer control precision: long-term, high-speed scanning micro welding in the input voltage, the power of a wave, the calculation of compensation data immediately change the welding energy, so that the welding does not occur due to voltage fluctuation in the fire bombing of weld or phenomenon, to ensure that each welding effect consistent, and welding sparks small, minimal impact on the battery, almost none

09: the operation set simplification: new panel design, the use of aluminum and metal buttons, durable, micro-computer of the parameters, the use of LCD liquid crystal display, keyboard adjustment, accurate intuitive ,convenient and more humane

10: Adjustable and easy to use, the new electrode design, solder pin spacing, pressure independently adjustable, for the original welding, alignment accuracy, high yielding,

11: sale low maintenance, easy maintenance, as the machine most of the use of imported components, to ensure low failure rate, and the spot welder structure design, maintenance, replacement of only one integrated circuit board, the general mechanics can be replaced

12: with automatic alarm and cut off the system, if the spot welder is damaged, will automatically display failure, and cut off the welding circuit to prevent the failure to expand, and to remind the repair

13: automatic counting, one output can be automatically counted 0-9999 facilitate the calculation of daily production

14: import solder pins: unlike ordinary welding ring used in further processing of the material to be shaped, which KEEPLEADER™ uses imported high-quality special welding products welding pins. And other three sets of import and distribution of each welding machine needle

A note about dual-pulse, capacitive discharge technology

Dual pulse spot welding is used for high quality, precision welding, there are two pulse for every actuation of the welder, the first pulse is a small fraction of the total pulse energy, it has the ability to clean the area to be welded by giving it a quick heat pulse, evaporating surface water vapor, oil, oxides and other contaminants, it also establishes a good, high conductivity area for the second, or welding pulse, the seconds pulse fuses the two pieces together, the area of the weld is very small, the piece remains cool, and the electrical conductivity and strength are high because two piece are alloyed over the spot surface, the spot welder at KEEPLEADER™ is passed SGS audited

Dual pulse, capacitive discharge spot welder is particularly good for welding batteries, wires, jewelry, steel, stainless steel, chromium and other passivity surface, so far, most of spot welder at KEEPLEADER™ is applied in field of battery spot welding  

Capacitive welding has the advantage of quick an stable energy release, and manageable energy input, this means that welds occur fast enough that spots are small and have very small heat effected zones, KEEPLEADER™ adopts made-in-Japan capacitors that has better performance and life-span  

The welder can be operated on standard household voltage and powers

Battery pack/cell manufacturer/builder require spot welders for tab welding and battery pack assembly, this small battery terminal welder is ideal for battery packs and tabs and contacting sheets

Dual pulse industrial spot welders of KEEPLEADER™

01: Dual pulse operation removes surface inconsistencies

02: Dual pulse operation removes surface inconsistencies and contaminants

03: Adjustable pulse width, much more finesse that transformer based welders

04: Available 125, 250, 500 and 875 Joule (125, 250, 500 and 875w a second)

05: Adjustable from 1% to 100% energy discharge

06: Up to 600 welds/min

07: Simple, user-friendly interface, potable size

08: Perfect for battery pack assembly

09: Hi Visibility display shows weld parameters

This dual pulse, capacitive discharge spot welders are easy to use as well as powerful, CD (capacitive discharge) spot welder is a version of resistance fusion welding that offers high peak currents with extremely fast pulse rise times and short durations (on the order of 10’s of microseconds), the short pulse lengths and high current allows the welding of high conductive materials, including copper, and brass, welding current and pulse widths may be adjustable to weld more resistive materials such as steel, and Nickel, capacitive discharge welding produces repeatable welds, independent of local line voltage variations and is capable of extremely fine energy adjustment, the dual pulse weld setting helps eliminate surface inconsistencies, contamination and allows adjustment of the initial contact of the welding electrodes to produce repeatable effects

KEEPLEADER™ can make modification on our current design to satisfy special requirements in diversity, welcome to filed inspection




Capacitive Discharge Battery Spot Welder is acceptable for Customized Spot Welding Process in Cylinder Cell Battery assembling
