Key specs explained
Max. Laser Power: 200W
This value indicates the maximum energy output of the laser source. A 200W rating allows for deeper penetration into metal compared to lower wattage units. You can use this power level to weld thicker sections of gold, silver, or platinum efficiently. Higher wattage generally means faster welding speeds and stronger joints for standard jewelry repair tasks.
Welding Depth: 0.1-3mm
This range defines how deep the laser can penetrate the material during a single spot weld. You can reliably join metals with thicknesses up to 3mm. This specification is critical for resizing rings or repairing broken chains without damaging the surrounding area. Ensure your project pieces fall within this depth range for optimal results and structural integrity.
Spot Adjustment Range: 0.3-2.5mm
This feature lets you control the size of the laser spot on the workpiece. You can adjust the spot from a fine 0.3mm point for delicate work to a broader 2.5mm area for covering larger gaps. This flexibility helps you manage heat input and precision. Smaller spots offer higher precision, while larger spots provide faster coverage for broader repairs.
Cooling System: Built-in water cooler
The machine includes an integrated water cooling system to manage heat during operation. This built-in feature eliminates the need for external chillers, saving space in your workspace. Effective cooling protects the laser source from overheating and extends the lifespan of the equipment. You can operate the unit continuously without worrying about manual temperature management or additional external hardware.
Voltage: 220V 1 phase
This specification indicates the electrical requirement for the machine. You must connect this welder to a 220V single-phase power outlet. It is not compatible with standard 110V household circuits without a transformer. Verify your workshop power supply before installation to prevent damage to the unit. This voltage ensures stable power delivery for consistent laser performance during jewelry welding tasks.
Design and Build Details
The ZAC 200W Jewelry Laser Welder, model LJW-200W, is built for high-precision tasks. According to the listing, it features a ceramic reflector in the laser pump chamber. This component is described as imported, corrosion-resistant, and high-temperature resistant. These traits support high electrical and optical conversion rates. This design helps maintain stable output during welding. The stable output prevents oxidation and blackening of the product. This is critical when working with precious metals like gold, silver, titanium, and platinum. The machine handles spot welding, perforating, and repairing. It also manages retipping, resizing, and gap bridging for small accessories and glasses frames.
The unit includes a built-in water cooling system rated at 1P Class 1 0.39mW. This system manages heat during operation. The listing notes a flexible and omni-directional adjustment of the blowpipe. This feature allows you to position the laser beam precisely. The machine also uses a special microscope observation system with crosshairs. This setup aids in accurate placement of the weld. A high-speed electronic filter device is included to protect the operator’s eyes. The listing states the unit stands 16.5 inches tall. This vertical footprint fits into standard jewelry workspaces. The design prioritizes precision and operator safety over bulk. You get a manual or operation video in English. Technology support is available online or via remote control.
Setup and daily operation guide
You set up the ZAC 200W Jewelry Laser Welder by connecting it to a 220V single-phase power source. The unit includes a built-in water cooling system, which you must ensure is functioning correctly before operation. This closed-loop cooling is essential for maintaining stable laser output during extended use. The machine ships with an English manual and operation video to assist with initial configuration. You will also receive technology support via online or remote control channels if you encounter setup questions.
In daily use, you adjust the laser frequency between 0 and 50 HZ to control the pulse rate. The spot size ranges from 0.3 to 2.5 mm, allowing you to fine-tune the weld area for different jewelry components. You select a pulse width between 0 and 20 ms to manage heat input. This precision helps prevent oxidation or blackening of gold, silver, titanium, or platinum pieces. The flexible blowpipe permits omni-directional adjustment, giving you control over the laser angle.
You operate the machine through its special microscope observation system. This system includes crosshairs for accurate targeting and a high-speed electronic filter to protect your eyes. The 1064 nm wavelength ensures consistent spot welding for repairs, resizing, and gap bridging. The ceramic reflector in the pump chamber supports stable performance. You rely on the 200W power output to achieve welding depths between 0.1 and 3 mm. This setup supports precise work on small accessories and glasses frames without damaging surrounding materials.
Before You Buy This Welder
Owning this ZAC 200W Jewelry Laser Welder requires careful attention to your workshop environment. You must verify that your facility provides a stable 220V single-phase power supply. The unit relies on a built-in water cooling system, so you need a compatible water source and regular maintenance to prevent overheating during extended use. Ensure your workspace has adequate ventilation, as laser welding can produce fumes. You will also need appropriate safety eyewear, as the listing mentions a high-speed electronic filter for operator protection, but additional personal gear is wise. This machine is designed for precise spot welding on gold, silver, and titanium. It fits well if you specialize in delicate repairs like retipping or resizing. However, if you need higher power for thicker metals, consider the 200W with CCD option or other higher-wattage models available. Always check the specific voltage requirements of your local grid before installation.
Check before you buy
- Verify your shop has a 220V single-phase power outlet.
- Ensure you have a reliable water source for cooling.
- Check compatibility with your local electrical grid standards.
- Confirm you have proper safety eyewear for laser work.
