A note about dual-pulse, capacitive discharge technology

Dual pulse spot welding is used for high quality welding. There are two pulses 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 second 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 the two pieces are alloyed over the spot surface.

Example capacitive discharge weld pulse

This method is particularly good for welding batteries, wires, jewelry, steel, stainless steel, chromium and other passivated surfaces.

Capacitive welding has the advantage of quick energy release, and manageable energy input. This means that welds occur fast enough that spots are small and have very small heat effected zones.

The welder can be operated on standard household voltage and powers.

Battery manufacturers require spot welders for tab welding and battery pack assembly. This small battery terminal welder is ideal for battery packs and tabs and contacts.

Dual Pulse Industrial Spot Welders

• Dual Pulse operation removes surface inconsistencies and contaminants
• Adjustable pulse width, much more finesse than transformer based welders
• Available 160 Joule (160 watt-seconds)
• Adjustable from 1% to 100% energy discharge
• Up to 600 welds/min
• Simple, user-friendly interface, portable size.
• Perfect for battery pack assembly
• Hi visibility display shows weld parameters

These Dual Pulse CD welders are easy to use as well as powerful. CD (Capacitive Discharge) welding 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 highly conductive materials, including copper and brass. Welding current and pulse widths may be adjusted to weld more resistive materials such as steel and nickel. CD 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 results.
