Description
Why Choose This Scotle QCW Fiber Laser Portable Spot Welding Machine?
High-Precision QCW Fiber Laser Welding
Powered by quasi-continuous wave (QCW) fiber laser technology at 1080 ±5 nm, this machine delivers stable laser output with precise heat control, ensuring clean spot welds with minimal thermal impact.
Ideal for Thin Stainless Steel & Thin Metals
With up to 6 J single-pulse energy and pulse frequency up to 300 Hz, it is specially optimized for thin stainless steel and delicate metal parts, effectively reducing burn-through and material deformation.
Fully Adjustable Welding Parameters
Users can precisely adjust pulse frequency, modulation frequency, duty cycle, and single-pulse energy to match different materials, thicknesses, and welding requirements.
True Portable Briefcase Design
Weighing only 11.5 kg, the briefcase-style structure allows easy transport and quick deployment, making it ideal for workshops, on-site maintenance, and mobile welding tasks.
Touchscreen Control with Preset Programs
The 5-inch touchscreen controller supports up to 19 customizable welding programs, enabling fast process switching and consistent, repeatable welding results.
Flexible & Comfortable Operation
Supports both foot pedal control and manual inching control, providing operators with greater flexibility and comfort during precision spot welding.
Air-Cooled, Low-Maintenance System
The air-cooled design with integrated dust filter eliminates the need for water cooling, reducing maintenance while ensuring stable long-term operation.
