JF20 Series Air-Cooled Handheld Laser Welding Machine Product Introduction 1. Product Overview JF20 series air-cooled handheld laser welder is a lightweight portable fiber laser welding equipment independently developed by JF Laser, including two power models: JF20-500 (500W) and JF20-800 (800W). Equipped with pure air cooling system, it abandons the bulky water tank of traditional water-cooled welders. The lightest main unit is only 15.9KG, with a lightweight separate wire feeder for single-person operation. This all-in-one machine integrates welding, rust removal and laser cleaning functions. It is widely applied in hardware processing, door & window guardrail manufacturing, sheet metal fabrication, mechanical equipment maintenance and aluminum alloy production, compatible with mainstream metals like stainless steel, carbon steel and aluminum. 2.

4. Core Advantages

1. Lightweight Air-cooled Structure for Portable Work No water tank, no coolant replacement or pipeline maintenance. Far lighter than traditional water-cooled welders, easy to transport to construction sites and on-site maintenance jobs, cutting labor and transport costs.
2. Universal 220V Household Power Supply Works with standard domestic sockets without special industrial power transformation, perfect for small workshops and outdoor operations.
3. Multi-function: Welding + Rust & Paint Cleaning One machine finishes metal welding, oxide layer removal and paint stripping. Wide 120mm cleaning width greatly improves processing efficiency, saving extra equipment investment.
4. Easy Operation & Perfect Weld Effect User-friendly handheld torch, new operators can master quickly. Smooth, low-deformation weld seams reduce post-grinding workload; matched wire feeder fills wide gaps perfectly.
5. Strong Environmental Adaptability Stable operation under low temperature (-20℃) and high humidity workshop conditions. Standard laser interface for easy parts replacement and low long-term maintenance cost.

5. Applicable Materials & Industries

• Materials: Stainless steel, carbon steel, cold rolled plate, aluminum alloy, galvanized sheet
• Industries: Kitchen hardware, advertising decoration, sheet metal cabinet, construction guardrail, machinery repair, metal surface renovation

6. Standard Package Complete set includes laser main unit, 7m handheld welding torch, 4.6KG independent wire feeder. Compatible with argon and nitrogen shielding gas, ready to use after delivery.
