The RSR-5K/10K is a portable capacitor-discharge stud welding machine powered by a high-capacity lithium battery, purpose-built for insulation pin applications. Combining an inverter charging circuit, a 32 Ah LiFePO4 battery and a super capacitor, it delivers strong, consistent welding energy for carbon steel and stainless steel bolts, pipe and marine insulation pins — even in demanding field conditions.

• Inverter charging circuit with low power consumption
• 32 Ah large-capacity LiFePO4 battery for safe, reliable operation
• 100,000 µF super capacitor for stronger welding energy
• Two guns can work alternately; over 5,000 insulation pins per full charge
• Battery voltage monitoring, adjustable capacitor voltage and real-time charge display
• Complete protection circuit with over-heating and over-current protection
• Suitable for carbon steel and stainless bolts, pipe and marine insulation pins
• Three-proof design (dust-, moisture- and corrosion-resistant) on key parts for reliable operation in harsh environments

Every unit is tested before shipment. Input voltage, torch and cable configuration, OEM branding and shipping options are confirmed with our sales team.
