Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of Factory Water‑Cooled Handheld Laser Welding Machine in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.

In plain terms, it's a fiber laser gun that puts 1000W to 3000W of energy right at your fingertips, hooked up to a water-cooled base unit. Think of it as the upgraded version of traditional TIG or MIG welders. The big advantage? It zaps the metal so fast that there's barely any heat spread, which means much less warping on your thin sheets. We designed this unit to be the go-to Compact Air-Cooled Laser Welding Machine for workshops that need to switch between stainless steel, aluminum, and galvanized plates without dragging a monster power supply around.

Stainless steel is a favorite for this machine. Because the beam is so focused, the weld pool stays clean, requiring almost zero post-grinding. For aluminum, we had to be careful. Aluminum reflects a lot of light, so we adjusted the beam's focus profile to actually "bite" into the surface instead of bouncing off. That's why the 3000W version performs noticeably better on thicker aluminum sheets (up to 6mm in our field tests). We also use a high-quality WSX LCN03A welding head, which gives you that precise spot control so you don't burn holes in thinner material.

We try to keep our service honest. When you buy this, you aren't buying a black box. Installation is literally plug-and-play: connect the water, gas, and power, and you are 80% there.

We do recommend you keep spare protective lenses and gas nozzles on hand because those are the only consumables you'll wear out. We actually include a small kit with your first order to get you started. Over time, the water-cooling system needs periodic cleaning, but that's about it. It's designed for low maintenance; we don't want you spending half your day fixing it.

We don't just market this stuff; we build it. Hebei Juliang Technology has been in the metal fabrication game since 2014. We went through three factory expansions (2018, 2022, and 2025) because our customers kept coming back, not because we oversold to them.

Our Quality Control is what sets us apart: Every single unit goes through a burn-in test before packing. We power it up, run it continuously, and check the beam stability. We also hold invention patents and utility model certificates-we aren't just assembling OEM parts. Our after-sales engineers are available 24/7 via video support. If a part fails, we don't just send you a video; we guide you through the replacement step-by-step on a live call.

Key Component Breakdown:

Laser Generator: Raycus (Stable power output).

Controller: CypCut L5210H (Intuitive interface).

Welding Head: LCN03A (Focus control is very accurate)

Cooling System: Standard water cooler included.

Warranty: 1 year full machine, 2 years on the laser source.

Which model fits your workshop best?

We have to be honest: if you are only welding thin sheets (under 3mm) and prioritizing cost, the 1500W is more than enough. But, if your jobs involve aluminum thicker than 4mm, skip the smaller ones and go straight for the 2000W or 3000W. We've seen customers buy the cheaper one and regret it later. It's better to buy the Compact Air-Cooled Laser Welding Machine that matches your average workload rather than your "dream" workload.

Frequently Asked Questions (FAQ)

1. Is this handheld laser better than a traditional TIG welder for thin sheets?
Yes, but for different reasons. TIG is great for precision but slow and requires high skill. This laser is about 2-3 times faster and puts much less heat into the metal, meaning your thin sheet (like 1mm stainless) won't warp. However, TIG still has a slight edge if you are welding extremely thick structural steel (over 10mm) where filler wire feeding is critical.

2. What welding wire does this machine require?
It's not standard for this unit to run a continuous wire feed like a MIG welder. We use a manual filler rod or a wire feeder attachment. For stainless steel, we recommend a 308L or 316L filler rod. For aluminum, you need an ER4043 or ER5356 wire. The laser melts the base metal, and you dip the rod into the pool.

3. How do you actually train a new operator for this?
We don't leave you guessing. Our engineers provide remote video training during installation. It usually takes an operator about 2 days to get the "feel" for the handheld gun. After a week, most people are producing stable, neat beads. We also have a free sample-making service where we can provide parameter settings for your specific material thickness.

4. Can this handle both square tube welding and flat sheet edge welding?
Absolutely. That's the beauty of handheld units. We've seen it used for corner welds on cabinets, edge-to-edge welding on sheet metal, and even pipe welding. The light weight of the gun means you can position it at any angle. Just make sure you have a rotating positioner for round pipes to keep the weld consistent.

5. What kind of maintenance mistakes ruin the machine quickly?
The biggest one we see is ignoring the water cooler. If the water level gets low or you use tap water instead of distilled, the laser source can overheat within 15 minutes of heavy use. Another common error is forgetting to check the protective lens for spatter. A cracked lens will scatter the beam and ruin the weld depth.
