Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of 1500w‑3000w handheld water‑cooled laser welder industrial metal welding equipment 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.

This handheld water‑cooled fiber laser welding machine is a practical industrial workhorse built for real‑world metal fabrication and repair jobs. Built‑in water‑cooling design enables long‑duration non‑stop operation, keeping core laser components at stable temperatures even during extended shift work.

Lightweight handheld welding gun delivers great maneuverability, letting operators handle corners, curved surfaces and hard‑to‑reach positions that fixed‑mount welders struggle with. It works reliably on stainless steel, carbon steel, aluminum and copper, producing narrow heat‑affected zones, minimal workpiece distortion and smooth weld beads that need little post‑grinding.

Many units combine welding, cutting and surface cleaning in one setup, saving extra equipment investment. The intuitive control panel allows quick parameter adjustment, so new operators can become productive without lengthy training.

Well‑suited for workshop production as well as on‑site field repairs. It serves broad sectors including hardware processing, sheet metal work, agricultural part restoration and custom exhaust manufacturing. Multiple power options are available, delivering consistent performance for small‑shop repairs through to heavy‑duty two‑shift industrial workflows.

advantage

Water‑cooled continuous operation

Professional water‑cooling system ensures stable temperature for laser source, supports long‑hour non‑stop running for double‑shift production, extends laser service life.

Flexible handheld operation

Light‑weight welding torch, easy to reach corners, curves and irregular workpieces. Suitable for both workshop use and outdoor on‑site welding.

Superior welding quality

Concentrated laser energy, narrow heat‑affected zone, low workpiece deformation. Smooth weld seam, greatly reduces post‑grinding workload.

Wide material compatibility

Works well on stainless steel, carbon steel, aluminum, copper and alloy metals. Optional multi‑function model supports welding, cutting and oxide cleaning.

Easy‑to‑use control system

Simple parameter setting, preset welding modes. New operators can master operation quickly without rich welding experience.

Low running cost

Less consumable loss compared with TIG / plasma welding. Lower scrap rate, improves overall working efficiency.

This machine handles stainless, carbon steel, aluminum alloys, and galvanized sheet without a fuss. Thinner materials-0.5mm to about 6mm-are where it really shines. You can also weld dissimilar metals, like stainless to carbon, with the right filler and gas shielding.

But don't expect it to weld cast iron reliably-the carbon content causes cracking during solidification. And if you're working with zinc-coated material, you'll need proper extraction-the fumes are no joke.

Installation & setup-day one

We ship these machines pre‑aligned from the factory. For you, that means uncrate it, connect the chiller hoses, plug in power, and add the coolant. The control panel is intuitive-joystick control for the weld head, digital readout for power and wire feed speed. Most operators are running good beads within 20 minutes, and clean welds within an hour.

If you're doing complex work-corner joints, lap joints, vertical seams-we include a library of pre‑set parameters. Select your material, enter the thickness, and the machine suggests a starting point. Fine‑tune from there based on your results.

1. We already have an argon arc welding machine, so buying another one won't solve any specific issues. Our main problems are thermal deformation and slow welding speeds. For thin plates, argon arc welding causes warping that requires time-consuming flattening. This laser welder, however, uses concentrated heat with a narrow weld seam. Stainless steel up to 2mm thick shows virtually no deformation. Plus, it's 3 to 5 times faster, meaning jobs could be finished by noon, freeing up staff for other tasks in the afternoon.

2. What makes water cooling better than air cooling? Do I need a separate water supply for this machine?
With air-cooled welders, power drops and inconsistent weld colors appear after about an hour of continuous use. Water cooling uses circulating liquid to dissipate heat, ensuring stable power throughout. This machine has a built-in, closed-loop water cooling system, so no external hookup is needed. A single fill of distilled water lasts over six months, with simple periodic replacements.

3. I primarily weld galvanized plates and aluminum alloys. Can this machine handle them, and what should I watch out for?
Yes, it can weld galvanized plates, but the zinc vapor will dirty the protective lens. Make sure to boost the auxiliary blowing air during welding. A good exhaust system is also essential for all laser welding, not just this machine. For aluminum alloys, you'll need the dual-wire feeding option, as standard single feeders struggle with soft aluminum wire and can jam.

4. If I decide to buy one, how can you guarantee it'll work right out of the box? How long does setup take?
Each unit undergoes a 24-hour full-power stress test before shipping. Once it arrives, we'll provide remote video guidance for wiring and settings. An electrician with typical skills should be able to go from unpacking to making the first good weld in about two hours. If your site is particularly complex, an engineer can also be sent for on-site setup. Please let the sales team know in advance.

5. After a few years, what parts typically need replacing, and what's the approximate cost?
Protective lenses are the most common replacement. For galvanized plates, one might be ruined in just two or three days. Domestic lenses are about 40-50 yuan, while imported ones cost over 100 yuan. The wire feeder wheel needs replacement roughly every 200 kg of welding wire. The laser and cooling pump head generally last three to five years with normal use, but it's crucial to change the cooling fluid regularly. Many people skip this, causing pump heads to rust, which isn't covered by warranty, so please keep this in mind.
