LBS Series Capacitor Discharge Stud Welding Tool

The LBS Series CD Stud Welding Tool (from manufacturers like Bolte / LBH) is a compact, high-performance welding machine designed to join studs (threads or pins) to metal surfaces using the capacitor-discharge process, which generates a very short, controlled welding arc (typically 1–3 ms). This method is especially valuable when welding on steel, stainless steel, aluminum, and brass sheet metal, where clean aesthetic welds and minimal backside marks are needed. The welder’s power electronics include a capacitor bank (e.g., 66,000 µF for LBS-75) and an inverter-controlled charging circuit, enabling rapid recharge cycles, high reliability, and consistent performance. The front panel provides a continuously adjustable charging voltage (e.g., 60–200 V) via a rotary knob, plus indicators (LED or digital) for status and error warnings. Lightweight and portable, the unit is built for workshop or site use, with robust housing rated to IP21 (or similar) depending on model. Compatible welding guns include contact-mode or gap-mode types (PKM-1B, PHM-1A, PIM-1B), giving flexibility for different stud geometries. Designed to meet standards like DIN EN ISO 14555, the LBS series supports both threaded and non-threaded stud welding with repeatable, high-quality results.
