Overview
Product Overview
The RoboWeld-SW350 is a high-output spot welding system engineered for demanding industrial automation environments. Designed for seamless integration into modern production lines, this 350kVA robotic welder delivers exceptional throughput and repeatability—ideal for high-volume automotive, appliance, and structural metal fabrication applications. Its dual-gun configuration enables simultaneous or staggered welding cycles, boosting line efficiency by up to 40% compared to single-gun systems. Certified to ASME Section IX standards, the RoboWeld-SW350 ensures full traceability, process validation, and compliance with rigorous quality management systems.
Optional explosion-proof certification (ATEX/IECEx-ready) makes it suitable for hazardous environments involving flammable gases or dust—such as battery module assembly or aerospace component manufacturing. Precision-controlled current delivery, adaptive squeeze force feedback, and real-time weld monitoring ensure consistent nugget formation even on coated, galvanized, or dissimilar metals up to 16mm total stack thickness.
