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 current-limited 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. The 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.
Note: simple transformer-rectifier based PB chargers are not usable, as they do not feature current limitation. For the same reason, do not connect the module directly to a battery, as this will lead to uncontrolled current flow and possible damage of the module.
The key specifications are:
Performance when used with kWeld:
You receive a complete board that is ready to go, including mounting hardware and two short connecting cables (AWG8 with crimped cable lugs on both ends) that replace the stock kWeld battery cables.
