Portable Marking for Large & Installed Parts
- A lightweight tethered head brings the marking field to large, heavy or already-installed workpieces that cannot be placed under a fixed desktop scanner.
- The standard J20H configuration uses a 20 W, 1064 nm Q-switched fiber source for permanent identification on metals and selected laser-markable plastics.
- An optional rechargeable battery can support mobile work; reference endurance is up to about six hours and must be confirmed under the intended duty cycle and ambient temperature.
- Shoulder straps, a trolley case or a portable support stand can be selected according to transport distance, head positioning and workpiece access.
- The embedded touchscreen application manages files and recipes. USB and Wi-Fi transfer are configuration-dependent and must be confirmed in the quotation.
- The contact or surface-detection input, emergency stop and trigger logic are supplementary safeguards. Operation still requires a Class 4 laser controlled area, beam barriers, access control, 1064 nm PPE and fume extraction.

Applications & Material Testing
Use the handheld head for serial numbers, asset IDs, logos, QR codes and Data Matrix marks on large or difficult-to-move parts. Maintain the specified standoff and keep the head stable against a verified reference surface during each cycle.
Standard 1064 nm fiber marking is best suited to metals and selected laser-markable plastics. Rubber, ceramics, glass, acrylic, leather, fabric and stone require separate feasibility testing and often a UV or CO2 laser instead.
Typical qualified uses include machinery, tools, molds, vehicle parts, rail and energy equipment, installed structures and maintenance identification. Safety-critical and regulated components require a documented marking procedure.
Mobility does not make uncontrolled outdoor use safe. Establish a temporary or permanent laser controlled area, contain direct and reflected beams, restrict bystander access and capture process fumes at the source.
For turbines, engines, bearings, ships, molds, rail vehicles and other large assets, send the exact alloy, coating, surface geometry, access photos, required code, durability target and available safety perimeter for review.
System Components & Options
Embedded Touchscreen Marking Control
The J20H-style controller uses an embedded Windows touchscreen and a machine-specific marking application. File transfer, barcode libraries, recipe storage and network functions depend on the supplied software. Do not assume desktop JCZ/EZCAD2 or LightBurn compatibility unless the exact board and driver are named.
20 W Q-Switched Fiber Laser Source
The standard handheld model is built around a 20 W, 1064 nm Q-switched source. A 30, 50 or 100 W system is a different configuration with different power, battery, cooling, weight and safety requirements and must be quoted separately.
Integrated Marking Controller
The controller synchronizes the source, scanner, red-light preview, surface-detection input and trigger. Confirm the software version, supported code types, I/O and data-transfer methods before ordering.
Handheld Galvanometer Head
The compact dual-axis scanner projects the job through a fixed field lens. Usable speed and placement depend on mark density, material response, standoff, head stability and code-grade requirement.
Optional Jewelry Rotary Fixture
A rotary accessory can support compatible rings or bracelets when the head is mounted in a stable stand and the controller provides calibrated rotary-axis support.
Flat-Part Positioning Fixture
A fixture or template can stabilize tags, plates and repeat parts under the handheld head. Fixture material, standoff and beam path must be included in the safety review.
Optional Cylinder Rotary
A rotary can mark compatible metal cups or cylindrical parts with the head mounted securely. Standard fiber is not the normal choice for glass bottles; use CO2 or UV testing for glass.
Handheld Fiber Laser Marker FAQ
Which materials can the J20H handheld marker process?
It is intended primarily for metals and selected laser-markable plastics. Send the exact material grade, coating and finish for testing. Glass, clear acrylic, wood, leather, fabric, stone and many ceramics are normally better matched to UV or CO2 systems.
What is the standard laser power?
The J20H-style standard configuration is 20 W. Other power levels change the source, electrical load, cooling, weight and battery requirements and must be identified as separate configurations.
How deep can it engrave metal?
Depth is not a fixed rating. It depends on alloy, surface, lens, focus, hatch, speed, pulse behavior and number of passes. Request a measured sample when depth is an acceptance requirement.
How does fiber marking differ from CO2 marking?
A 1064 nm fiber laser is generally selected for metals and certain plastics. A 10.6 µm CO2 laser is generally selected for wood, PMMA, paper, leather, textiles and many coated nonmetals. Material absorption and the required mark determine the choice.
How should the handheld optics be maintained?
Power down and secure the system before inspection. Keep the contact spacer and protective window clean, avoid touching optical surfaces, and use only the approved optical tissue, swab and solvent. Damaged internal scanner optics require qualified service.
Which files and codes are supported?
The embedded application can support text, serial data, QR codes, Data Matrix, barcodes and graphics through its documented import formats. Confirm the exact software version and test representative production files before shipment.
What are the battery, source-life and warranty terms?
Battery endurance, source life and warranty depend on the selected source, battery capacity, duty cycle, temperature, charging practice and covered components. The signed quotation must state the test condition and warranty scope.
What safety controls are required for mobile marking?
This is an open-beam Class 4 process. Use a laser controlled area or compliant enclosure, beam-resistant barriers, interlocks or access control, 1064 nm-rated eyewear selected by the safety assessment, fume extraction, training and a documented procedure. Contact detection and an emergency stop do not replace these controls.
