Ultra Precision Spot Welding Suitable for thin metal welding from 0.1mm to 2mm with clean and precise welding spots. Small Heat Affected Zone Low heat input reduces deformation, discoloration, and material damage. Portable and Compact Design Compact machine structure with flexible operation for different working environments. Easy Operation System Touch screen control system with parameter storage, easy to operate even for beginners. Air Cooling System Air cooling design reduces maintenance cost and makes the machine more convenient to use. Applications The QCW laser spot welding machine is widely used in: Thin sheet metal welding Stainless steel products Hardware repair Advertising letters Lighting products Metal fabrication workshops Artistic decor Kitchenware Small metal parts welding Metal box and enclosure welding Maintenance and repair work Note: This machine is not a microscope jewelry welding machine. It is mainly used for thin metal sheet welding and general metal fabrication applications. Difference Between Portable Spot Welder and Microscope Laser Welder Portable QCW Laser Spot Welder is designed for thin sheet metal welding, hardware repair, and general metal fabrication without microscope positioning. Microscope Laser Welding Machine is designed for jewelry welding, micro components, and ultra-precision welding applications requiring microscope observation. This portable model focuses on flexibility, portability, and thin metal welding, while the microscope model focuses on micro welding and jewelry repair.
