Check out real marking examples from busy fabrication environments. This gallery shows deep, clear tracking codes on steel tubes, tools, aluminum parts, black tires and iron castings. These marks will not fade or wear off over time.
Different jobs need different setups. Use this simple guide to find the right laser wattage and power supply for your workshop or warehouse line.
Best for standard marking jobs. Choose 30W if you mark metal nameplates, plastic tags, small tools, or smooth steel bars. It easily prints crisp serial numbers and text on a budget.
Best for deep or high-speed jobs. Choose 50W if you engrave rough iron castings, deep metal parts, or large pipes. It completes large batch work faster to save factory labor time.
Plugs into any standard shop wall outlet. Best for permanent production lines that run non-stop all day without needing to recharge.
Equipped with a built-in 22.2V lithium battery pack for 3-4 hours of cordless work. Perfect for tracking inventory in remote storage yards or areas without power outlets. Note: This option must be chosen at the time of purchase and cannot be added later.
Do not guess your machine setup and risk getting weak marks. Contact our support team today, tell us about your metal materials, and our technical engineers will help you choose the right laser power and power source for free.
Looking for a reliable setup for your factory? See how the HeatSign handheld laser engraver compares to other handheld options on the market. We focus on keeping your work safe, mobile, and easy.
The marking head weighs only 1.5 kg. It is easy to hold, so your hands will not tire during long marking jobs on the shop floor.
A cone shield covers the laser spot and blocks bright reflections to keep the operator safe during active use.
Move and adjust the slider easily to fit and trace metal parts of different sizes.
A fast fan under the head blows away smoke and dust to keep the glass lens clean and working perfectly.
Other gun designs are heavy, often over 2.5 kg. They strain your hands and are hard to hold steady during daily shifts.
Most basic choices have no face or eye shield. Stray laser reflections can easily hurt nearby workers.
A rigid frame cannot change its size, making it hard to mark small parts or narrow metal tools properly.
Without an active fan, smoke and dust stick to the lens, lowering power output and cutting code contrast.

Short, direct answers to the questions buyers ask before choosing a handheld fiber laser marking machine.
Mark first, treat later is the wrong order. Do surface treatments before laser marking for the clearest result.
If a part must survive years of harsh outdoor wear, use our Dot Peen Marking Machine instead. It presses deep dents that stay readable through coatings.
Yes, when the mark has the right contrast and grade.
It makes permanent serial numbers, VIN characters, barcodes, QR codes, and Data Matrix codes for automotive (IATF 16949 / VIN), aerospace (AS9132, MIL-STD-130 UID), and medical (FDA UDI) use.
Send your part and target standard. We mark a sample and check the code grade before you buy.
Treat it as a Class 4 laser. The 1064 nm beam is invisible, and reflections off shiny metal can hurt your eyes.
Every operator must wear laser glasses rated for 1064 nm. Normal or welding glasses do not protect you.There is one eye goggle come from the machine.
The head has a cone shield to block stray reflections. It is better use it in a controlled area, with good ventilation.
It works best on flat or near-flat surfaces.
The laser focuses at a set distance. On curved or uneven parts, the focus drifts and the mark quality drops a lot. So we suggest keeping to flat areas.
If you must mark pipes or curved parts, talk to us first — we can advise on focus spacers or fixtures.
No computer needed. The built-in 7-inch touch screen runs everything.
For logos and graphics, the software uses the PLT format. Other file types need to be converted to PLT first.
The system also makes serial numbers and dates that count up on their own, and can read a name list from a spreadsheet.
Upkeep is low. There are no inks, no gas, and no cooling water.
Main task: wipe the lens at the end of a shift. The built-in fan keeps most dust off while you work.
Every machine comes with a 1-year warranty, setup help, training videos, and lifetime online support.
Yes. You can keep marking while the optional 22.2V battery charges from a power source, so work never stops.
A full charge takes about 2 hours and gives 3–4 hours of cordless use — handy for remote yards or spots with no power outlet.
You have seen the specs, the power options, and the safety design. Now let’s make it real. Tell our engineers what you mark — pipes, castings, tags, or tools — and we will confirm the right wattage, lens, and power source, then send a clear price. No guesswork, no pressure.
When parts are too large, heavy, or already installed, a portable laser marking machine helps bring permanent marking directly to the worksite. See how users evaluate HeatSign’s portable laser after real setup, field operation, focusing, battery planning, and daily marking work.
We chose the battery version for marking parts in areas without easy power access. It works well for short field jobs and inspection tags. For a full day of work, we still plan charging time or keep AC power nearby. The portability is useful, but it is not unlimited runtime.
We use the 50W portable model to mark ID numbers on large steel frames before shipment. The best part is that we can bring the machine to the part instead of moving the part to a table. The mark is clear, but the operator still needs to keep the head steady and check focus before each job.
