Is this the right tool for your workshop?
If you are tired of the distorted heat marks left by TIG or MIG welding on thin sheets, you are not alone. We built this handheld water-cooled system specifically to solve the problem of thermal deformation in stainless steel and aluminum fabrication. It's not a miracle machine, but it is a massive upgrade in control.In simplest terms, it is a portable laser welding gun connected to a water-cooled power source. Unlike conventional machines that rely on bulky transformers, this unit uses a fiber laser source to deliver concentrated energy. It's the Compact Air-Cooled Laser Welding Machine solution tailored for operators who want to move freely around large frames without dragging heavy hoses. We focused on making the grip balanced to reduce fatigue, so you can weld longer without that wrist ache.

We did not just slap a laser on a box and call it a day. The real engineering challenge is in the optical path and the cooling system. When welding aluminum, the reflectivity is a nightmare for most lasers. We solved this by customizing the beam quality in the 1000W to 3000W range.

The water-cooled design isn't just a gimmick; it allows the machine to run consistently at high power without overheating. For stainless steel, the penetration depth is phenomenal because the beam stability stays precise, even when the ambient temperature in your shop rises. Compared to traditional carbon steel welding, these parameters demand a higher-grade collimator, which is why we use the LCN03A head to maintain focus.

You are Buying More Than a Machine

We are Hebei Juliang Technology Co., Ltd., and we've been in the CNC cutting and welding game since 2014. We've lived through three factory expansions (2015, 2018, and 2025) because our customers keep coming back for support, not just the products. We boast over 20 specifications available, from cutting to welding.

Our quality control isn't just paperwork. Every unit undergoes a rigorous burn-in test before it leaves our facility. We don't just send you a box; we send you a fully tested unit. This is how we maintain our reputation as a high-tech enterprise with invention patents. We stand behind our after-sales service with 24-hour remote video support and a team of engineers who have seen every fault imaginable.

A Real Story

One of our clients in the furniture industry faced severe warping when welding 1mm stainless steel tubing for modern office chairs. Standard welding caused the tubes to bend, ruining the final assembly.

Here is how we solved it:
Using the 1500W setting (as shown in our penetration table), we dialed down the pulse width. Because the focus spot is extremely fine, the heat input dropped by roughly 40% compared to MIG. The result? Zero burn-through and minimal post-weld grinding. We even saved them 30% on filler wire. This is the kind of practical efficiency we bring to the table.

Factory Production Flow

Raw Material Inspection: We source high-grade aluminum and steel for the chassis.

Frame Welding: Precision jigs ensure rigidity.

Stress Relief: Heat treatment to prevent future cracking.

Machining: We use gantry milling machines for accuracy.

Assembly: We integrate the laser source, controller, and cooling unit.

Testing: Each unit is fired up and tested on different material thicknesses.

Packing: Secured in wooden crates for international shipping.

The table below represents our standard configurations. We provide options for 1500W, 2000W, and 3000W power, which directly affect the max single-pass welding thickness. Based on our tests, here is what you can expect:

Laser Power	Carbon Steel (Max Single Pass)	Stainless Steel (Max Single Pass)	Aluminum (Max Single Pass)	Galvanized Plate (Max Single Pass)
800W	3mm	3mm	2mm	2mm
1200W	4mm	4mm	3mm	3mm
1500W	5mm	5mm	4mm	4mm
2000W	6mm	6mm	5mm	5mm
3000W	8mm	8mm	6mm	6mm

1. What is the difference between this handheld laser and a traditional TIG welder?
TIG is slower and relies on a tungsten electrode that wears down. This laser sends a concentrated beam that melts the base metal instantly. The result is at least twice the speed and far less distortion on thin materials, though TIG is still better for extremely thick structural steel over 10mm.

2. Does this machine require special gas?
Yes, you will need a shielding gas supply, typically Argon or a mix of Argon and Nitrogen. The gas protects the weld pool from oxidation. The machine itself is water-cooled, but the welding process still requires gas shielding to get that shiny, silver bead.

3. How hard is it to operate compared to a standard cutting machine?
If you have used a standard CNC fiber laser cutter, the software is similar. However, the handheld gun requires manual hand-eye coordination. We provide remote video training for your operators. Expect a learning curve of about 2-3 days to produce consistent, clean welds.

4. Which power rating is best for a stainless steel sink fabrication workshop?
For sink fabrication (typically 1.2mm to 2mm sheets), we strongly recommend the 1200W or 1500W model. It provides enough penetration without burning holes in thin sheets. It also reduces the required skill level for your welders.

5. How do you manage after-sales support for international clients?
We rely on a dedicated engineer team that provides 24-hour remote video support. For hardware issues, we guide you through diagnosis and send replacement parts (like lenses or nozzles) via express shipping. Our support service begins at purchase, not after.
