FAQ

Yes. The Laser Spot Welding machine is suitable for precision jewelry repair and other delicate welding applications.

However, welding results for diamond prongs, settings, and small tips depend on the material, structure, thickness, and welding parameters. Since these specific applications have not been fully tested, we recommend sending us samples for a welding test before ordering.

The minimum laser spot size of the Scotle air-cooled desktop model is 0.2 mm.

The adjustable spot-size range varies depending on the machine model.

The machine is suitable for welding various metals and alloys, including:

  • Gold
  • Silver
  • Karat gold
  • Stainless steel
  • Copper
  • Titanium
  • Platinum
  • Other compatible metal alloys

Actual welding results depend on the material’s reflectivity, thermal conductivity, thickness, joint design, and welding parameters.

The reference welding depths vary by model:

These figures are reference values rather than guaranteed results. Actual welding depth depends on the material, joint structure, laser energy, pulse width, spot size, and operator technique.

Sample testing is recommended for applications with specific welding-depth requirements.

The machine supports argon or nitrogen shielding gas.

Shielding gas is recommended when:

  • Welding easily oxidized metals such as titanium, stainless steel, or karat gold
  • A bright, clean, and oxidation-free weld surface is required
  • Producing deeper welds or larger molten pools
  • Welding reactive metals or alloys

The appropriate shielding gas should be selected according to the material and applicatio

The standard machine is primarily manually operated.

The operator positions the workpiece using the manual worktable, adjusts the focus, observes the welding area through the microscope or CCD display, and triggers the laser using the foot pedal.

Scotle air-cooled desktop model

  • Adjustable spot size: 0.2–3 mm
  • Reference welding depth: 0.1–1.5 mm
  • Manual lifting worktable: 100 × 100 × 150 mm

Scotle water-cooled vertical model

  • Adjustable spot size: 0.3–2 mm
  • Manual worktable
  • Manual focusing
  • Foot-pedal laser triggering

Specifications may vary according to the selected configuration.

The machine does not include a pre-installed process library.

However, it supports saving and recalling user-defined welding parameters, making it easier to reuse settings for similar materials and applications.

Rotary-axis compatibility depends on the machine model, structure, and control system.
Some models may support an optional rotary fixture, while others do not. Please contact Scotle to confirm compatibility before ordering.

Machine modelScreen sizeScreen magnificationMicroscope magnification
Scotle 200W air-cooled desktop model10.8 inchesUp to 25×10×
Scotle Mini7 air-cooled desktop model7 inchesUp to 20×10×
Scotle 200W water-cooled vertical model7 inchesUp to 20×10×

Display and microscope specifications may vary according to the selected configuration.

The standard microscope has a fixed optical magnification and cannot be continuously adjusted.

Please contact Scotle if your application requires a different viewing configuration.

.

The CCD camera uses a 700 TVL imaging chip and provides a clear, real-time view of the welding area for positioning and precision jewelry repair.

The exact camera and display configuration may vary by machine model.

The standard optical lenses are manufactured in China and selected according to the machine’s optical-system requirements.

Both air-cooled and water-cooled models are available.

  • Scotle air-cooled desktop models use an integrated air-cooling system and do not require an external water chiller.
  • Scotle water-cooled vertical models use an integrated water-cooling system to control the operating temperature.

Please select the cooling method according to the machine model, working environment, and expected operating time.

The standard configuration generally includes:

  • Microscope
  • CCD camera
  • Display screen
  • Foot pedal
  • Manual worktable
  • Protective lenses
  • Shielding-gas connection
  • Air-cooling or water-cooling system, depending on the model

The included accessories may vary by machine model and order configuration. Please refer to the final quotation and packing list.

Common consumables and replacement parts include:

  • Xenon lamp
  • Laser-head protective lens
  • Other optical protective components

The service life of the xenon lamp depends on the operating frequency, output energy, pulse width, cooling performance, and maintenance conditions.

There is no fixed replacement interval for every user.

The xenon lamp should be inspected and replaced according to its actual condition, operating frequency, output stability, and accumulated usage. Regular maintenance helps maintain stable welding performance.

Language availability depends on the machine model and controller version.

  • Scotle water-cooled vertical model: Chinese, English, Korean, and Russian
  • Scotle air-cooled desktop model: more than 10 languages

Please confirm your required operating language with Scotle before ordering.

Yes. Operators can adjust parameters such as laser energy, pulse width, frequency, spot size, and other available settings according to the material and welding requirements.

Parameter availability may vary depending on the model and control system.

Yes. Sample testing is recommended when you have specific requirements for welding depth, appearance, precision, material compatibility, or production efficiency.

Please send us the material information, thickness, application requirements, and sample photos. Physical samples can also be arranged for testing when necessary.
