# Lengwei GW/JW Laser M9 Desktop Portable Dual-Function MOPA Multi-Function Laser Engraver<br /> <br /> The Lengwei M9 desktop portable dual-function laser engraver features an MOPA tunable pulse width fiber optic light source, offering both **desktop vertical fixed engraving** and **portable handheld engraving** modes with quick switching. It excels at both precision engraving of small batches and on-site marking of large items, making it a versatile machine suitable for stores, hardware processing, gift customization, and engineering maintenance.<br /> <br /> ## ✅ Product Principle<br /> <br /> Equipped with a 1064nm MOPA fiber laser, featuring independently adjustable pulse width. With the升降立柱 (adjustable column) installed, it becomes a standard desktop engraver, enabling precise laser engraving of static workpieces on the platform. Remove the scanning frame to switch to the handheld gun mode for on-site marking of large, non-removable workpieces. Utilizes controllable thermal ablation technology to achieve oxidation discoloration, shallow engraving, anodized aluminum black marking, and colored marking on stainless steel, ensuring permanent and wear-resistant markings.<br /> <br /> ## ✅ Core Advantages<br /> <br /> 1. **Desktop / Handheld Dual-Function, Covers All Scenarios**<br /> Equipped with a quickly detachable adjustable column. With the column installed, it functions as a desktop machine, ideal for batch processing of nameplates, jewelry, and small hardware parts. Remove the column to transform into a handheld gun, enabling marking on large molds, tanks, vehicle frames, and steel structures without disassembly or transportation. Suitable for marking on vertical surfaces, arcs, and narrow spaces, replacing two machines with one and saving procurement costs.<br /> 2. **MOPA Light Source, Higher工艺上限 (Process Limit)**<br /> Compared to standard Q-switched fiber models, the tunable pulse width ensures fine shallow engravings without damaging the base material and powerful deep engravings. Stable performance for colored stainless steel marking, high-contrast black marking on anodized aluminum, and oxygen breakthrough marking on galvanized parts, preventing coating damage and accommodating high-end custom orders.<br /> 3. **Integrated Air Cooling, Simple Deployment**<br /> The entire machine features air cooling, eliminating the need for a water cooling unit and compatible with standard 220V power. Compact and lightweight design,方便门店摆放 (convenient for store placement), trade show exhibitions, and on-site demonstrations. Optional built-in battery version for outdoor construction work without power access.<br /> 4. **Smart Touch Control System, Full Functionality**<br /> Includes an industrial touch terminal, supporting import of DXF, PLT, AI, BMP, JPG, and other formats. Supports serial number流水 (flow sequence), dynamic QR codes, variable trace codes, and date/batch marking. Red light preview for positioning, one-click saving and calling of process formulas, making it easy for beginners to operate.<br /> 5. **Comprehensive Safety Protection, Adaptable to Complex Environments**<br /> Handheld head with safety trigger switch and light shield. Emergency stop protection in desktop mode, automatically cutting laser power on accidental operation. Shock-resistant body, suitable for multi-dust environments in stores, workshops, and construction sites. Only the protective lens is a conventional consumable, with no ink or consumables, reducing maintenance costs.<br /> 6. **Extensive Upgradability, Flexible Configuration**<br /> Can be upgraded with a rotating workholding fixture for ring and round tube circumferential marking. Optional fume extraction system. Optional CCD vision positioning for automatic small part identification and marking without fixtures in desktop mode.<br /> <br /> ## ✅ Materials Suitable for Processing<br /> <br /> Carbon steel, stainless steel, aluminum alloy, anodized aluminum, copper, brass, titanium alloy, galvanized parts, various coated metals; hard engineering plastics.<br /> <br /> > <br /> > Note: For transparent plastics, PCBs, and glass precision cold processing, use the Lengwei UV laser engraver. For non-metallic fabrics and wood, use a CO₂ cutting machine.<br /> <br /> ## ✅ Typical Application Industries<br /> <br /> - Gift & Jewelry Stores: Gold and silver jewelry, pendants, rings, metal nameplates, pet tags customization<br /> - Hardware Processing Factories: Small fasteners, tools, lock logos, batch numbering marking<br /> - Engineering Machinery & Steel Structure Maintenance: Vehicle frames, tanks, flanges, large mold on-site trace marking<br /> - Automotive Parts & Instruments: Component identification, maintenance markings<br /> - E-commerce Creators, On-Site Customization, Trade Show On-Site Engraving<br /> <br /> ## ✅ Machine Configuration Options<br /> <br /> Power: 20W / 30W / 50W MOPA versions<br /> Engraving Area: Standard 100×100mm, optional 150×150mm<br /> Power Supply: Plugged-in standard version / Battery-powered wireless portable version<br /> Standard Configuration: MOPA fiber laser, high-speed scanner, detachable adjustable column, handheld gun head, air-cooled main unit, touch control system, red light positioning, safety protection, marking software<br /> Options: Battery module, rotating workholding fixture, fume extraction system, CCD vision positioning, CE full export documentation<br /> <br /> ## ✅ Comparison with M8 Handheld Machine & Standard Desktop Engraver<br /> <br /> - Standard desktop all-in-one engraver: Only capable of static platform processing, unable to handle large or heavy workpieces;<br /> - M8 pure handheld engraver: Primarily for on-site maintenance, lacks a desktop stand, inconvenient for small batch processing;<br /> - ✅ Lengwei M9 dual-function machine: Combines desktop mass production and portable handheld use, MOPA light source supports colored marking and aluminum black marking, versatile for store orders and engineering maintenance.<br /> <br /> ## ✅ After-Sales & Service<br /> <br /> Lengwei Laser offers direct factory supply,整机质保 (整机 warranty), free sample engraving, remote teaching, and on-site debugging and training. For export orders, complete manuals and certification documents are provided. We are recruiting global agents for cooperation.
