The Portable Laser Spot Welder is a high-precision welding device integrating quasi-continuous wave (QCW) fiber laser technology. Featuring an integrated handheld design, it is compact, lightweight, and combines process flexibility with industrial-grade performance. Engineered specifically for precision welding in complex scenarios, this device is ideal for thin-sheet welding, sign letter welding, lighting fixture laser welding, and DIY handcraft projects.
The problem we actually solved
Program Number: Indicates the currently selected program number. Users can configure and store parameters for different welding processes, with the system supporting up to 19 custom program libraries.
Laser Power: Sets the laser output power for the current program, adjustable within a range from 10% to 100%.
Laser Frequency: Configures the pulse frequency for the current program, i.e., the number of laser pulses emitted per unit time (second).
Pulse Width: Defines the pulse duration for the current program, controlling the laser activation time for single-pulse energy output.
Modulation Frequency: Adjustable within a range of 1–20,000 Hz, used to set the base frequency of the PWM modulation signal.
PWM Duty Cycle: Provides stepless adjustment from 1% to 100%, precisely controlling the modulation duty ratio of the laser power.
Who is this actually for?
Let me be direct.
You want this machine if:
- You move between job sites (stairs, trucks, tight spaces)
- You're tired of maintaining water chillers
- You weld thin to medium materials (0.5–5mm)
- You want TIG weld quality with MIG weld speed
- Your shop floor is already crowded
You don't want this if:
- You weld 8mm+ plate all day every day (get water-cooled 3000W)
- You have a dedicated welding bay with existing chiller infrastructure
See? Honest. No upsell to a machine that doesn't fit your work.

Where customers are using air-cooled
Hardware processing (brackets, hinges, small parts) – Fast changeover. No chiller warm-up time.
Airtight component welding (sensors, housings, small containers) – Low heat input means no warping. Seals hold.
Electronics and medical devices – Clean welds. No spatter. No post-weld cleaning required.
On-site repair (rental equipment, farm machinery, trucks) – Throw the unit in a van. Drive. Weld. Drive back. No water to spill on the floor mat.
What customers actually say (paraphrased, but real)
*"I bought the water-cooled version from another brand. The pump died in month eight. Replacement pump cost $400. I sold it and bought JULIANG's air-cooled. Two years. Zero issues."*
- Fabrication shop owner, Texas
"We do stainless steel railings. The welds come out so clean we stopped using a grinder. That's 15 minutes per railing saved."
- Production lead, Ontario
"My guys kept forgetting to check the water level. Not a problem anymore."
- Operations manager, Melbourne
The company behind the machine (because trust matters)
Hebei Juliang Technology Co., Ltd. – in business since 2014. That's not ancient, but it's not "started in a garage last year" either.
Quick timeline:
·2014: Entered CNC cutting
·2018: Second factory expansion, JULIANG brand registered
·2020: First laser welding machines. Invention patents granted.
·2022: High-tech enterprise certification. Export begins.
·2025: Third factory expansion. Rated specialized/innovative enterprise.
Today: CE certified. Exporting to Africa (23%), Southeast Asia (18%), Eastern Asia (15%), Europe, Russia, US. Thousands of machines running worldwide.
What this means for you: When you email support, a real engineer responds. When you need a part, it ships from stock-not from a "let me check with the factory" black hole.
FAQ – The questions you'd ask if we were having coffee
Q: Does air cooling mean I can weld forever without stopping?
A: No. And anyone who says yes is selling you magic beans. Air cooling works continuously, but like any cooling system, it has thermal limits. In a 25℃ shop, the Portable Air-Cooled Handheld Fiber Laser Welding Machine runs full duty cycle at 900W–1200W. At 1500W–2000W, we recommend resting the unit for 5–10 minutes after 20–25 minutes of continuous welding. Water cooling handles longer heavy-duty cycles. Air cooling handles 90% of shop work. Pick based on your actual daily weld time, not theoretical maximums.
Q: Can this really weld 0.5mm thin material without burning through?
A: Yes-and here's why. Low heat input is the whole point of fiber laser welding. On thin materials, you adjust two settings: lower power and faster travel speed. The weld happens so quickly that heat doesn't have time to spread. We've welded 0.4mm stainless foil on a test stand. Not that you'd do that daily. But the capability exists. Start with our recommended parameters (ask us for the table) and tune from there.
Q: What happens if the air intake filter gets clogged?
A: The machine's thermal protection triggers and stops lasing. This is a feature, not a failure. The fix: unplug the unit, remove the dust filter (front panel, two thumb screws), blow it out with compressed air from inside-out, reinstall. Takes 90 seconds. If you ignore filter cleaning for months, you'll trigger thermal shutdown more often. We provide a washable spare filter. Rotate them monthly. Your machine will outlive your patience.
The only real question left
Do you actually need a water chiller? Or has the industry just trained you to accept one?
The Portable Air-Cooled Handheld Fiber Laser Welding Machine isn't for everyone. But for shops that move, that weld thin to medium materials, and that want one less thing to maintain-it's the machine that makes you say "why didn't I try this sooner."
Still not sure? Fine. Send us your most problematic part. We'll weld it on video. You watch. You decide. No pitch. Just proof.
