This module features six Maxwell BCAP0310-P270-T10 ultracapacitors with ultra low internal resistance, delivering more than 1000A of pulse current to the kWeld system, but the power delivery capacity of the module of up to 5kW enables the use of this module can also be used for a variety of other demanding applications.
Connect a suitable power supply to the inputs of the module, and the kWeld to its output terminals to create a stationery spot welding solution. Because it is modular, you can easily change back the system into a portable welder.
In order to weld with quick repetition rates, the kSupply module is recommended to power this module as it provides 70A of charging current. Whe welder consumes up to 500W of average input power during intense use. However, when a slower recharging speed can be accepted, the following options may offer a more affordable solution. An output current of at least 20A is recommended – the kCap user manual includes a graph that estimates the achievable welding repetition rate as a function of available current.
The key specifications are:
Performance when used with kWeld:
This product comes in two different flavors:
Without capacitors: you receive the circuit board with all components soldered – except for the BCAP0310 capacitors, in case you wish to source the capacitors by yourself and plan to solder them onto the board.
Complete: you receive a complete board that is ready to go, including two connecting cables (AWG8 with crimped cable lugs on both ends) that replace the stock kWeld battery cables.
