WELDMAN inverter rectifier Smart 100 12V/24V with start-up — vehicle charger and starter

WELDMAN Smart 100 is an inverter-rectifier for 12V and 24V vehicle electrical systems that combines a battery charger and a start-up (jump starter) function in one compact unit. It provides regulated rectification for controlled battery charging and inverter capability to deliver the high current pulses required for engine cranking. The device is intended for use with cars, vans and trucks as well as in workshop environments where reliable charging and starting assistance is needed.

Advantages

The WELDMAN Smart 100 supports both 12V and 24V systems, enabling flexible use across different vehicle types without additional adapters. Its inverter-rectifier design ensures stable charging profiles and protection against overcharging, while the integrated start-up function delivers a controlled high-current output for safe engine starts. Compact form factor and clear controls allow easy placement in a garage or service bay and straightforward operation by technicians.

How to use

Connect the WELDMAN Smart 100 to the vehicle battery following the polarity markings: positive clamp to positive terminal and negative clamp to chassis ground or battery negative terminal. Select the appropriate system voltage (12V or 24V) according to the vehicle, then choose the charging or start-up mode as required. Monitor the unit’s indicators during the charging cycle and disconnect once charging is complete or after a successful engine start. Follow standard safety procedures when working with batteries, including eye protection and avoiding sparks near the battery.

Recommendations

For best results, use the charger for regular maintenance charging to prolong battery life and perform start-up only when necessary; avoid repeated deep discharges. Ensure vehicle charging system faults are diagnosed and repaired in the workshop to prevent repeated battery drain. Store the unit in a dry, ventilated area and inspect clamps and cables before each use.
