Is the Kirin Laser LightWELD Handheld Laser Welding & Cleaning System Worth It?

In today’s metal fabrication world, every minute and every millimeter counts. Many workshops are switching to handheld laser welding and cleaning systems because they promise to simplify processes and save time.

Yes, the Kirin Laser LightWELD system is worth it for shops that need versatile, efficient welding and cleaning in one compact setup. It combines welding, cleaning, and cutting with consistent precision—ideal for small to medium fabrication needs.

When I first used this system, what struck me was how fast it cut down setup time. No more switching cables or tools between welding, rust removal, and seam cleaning. Everything was built into one handheld gun—simple, practical, and efficient.

How much does a laser welding machine cost?

Many buyers hesitate before investing in a laser welding machine because prices vary widely. It’s not just about wattage—it’s about what you’re actually getting for your money.

A high-quality handheld laser welding machine from Kirin Laser costs between $1,860 and $6,200, depending on power and configuration. The right choice depends on your material type, thickness, and daily production needs.

In my experience, the pricing sweet spot depends on output expectations. Here’s the breakdown of Kirin Laser’s pricing range for reference:

Why the cost makes sense

Laser welding machines save on consumables and reduce post-weld grinding. Over months, the ROI often surpasses that of TIG or MIG systems¹, especially when one machine replaces multiple tools. You’re paying not just for wattage, but for flexibility—especially when welding and cleaning are integrated.

I remember working with a small metal shop that used to buy separate welders and cleaners. Their combined setup cost was almost $8,000. When they switched to a 1500W Kirin Laser² handheld unit, they halved their investment and doubled their efficiency. The math was simple, and the impact was immediate.

Is handheld laser welding real?

It’s easy to think handheld laser welding is just another passing innovation. But step into any modern fabrication shop, and you’ll see it changing the workflow.

Yes, handheld laser welding is absolutely real. It’s a fiber-laser-based process that replaces traditional MIG/TIG methods with faster, cleaner welds and minimal distortion—all in a portable format.

How it actually works

A handheld laser welder³ directs a concentrated beam through a fiber cable to melt the joint area. Because it’s so focused, heat distortion and burn-through are minimal. Add in the cleaning mode, and the same unit can prep or polish metal surfaces with a simple mode switch.

My personal take

When I first held a Kirin handheld laser gun, I expected it to feel clunky. Instead, it was balanced, responsive, and surprisingly light. Switching from welding to cleaning mode⁴ felt like flipping a light switch. I remember thinking, “This is what MIG should have evolved into years ago.”

How thick of metal can a laser welder weld?

This is one of the first questions I get from distributors and fabricators. Everyone wants to know if handheld laser welding can really replace industrial-grade systems.

A handheld laser welder can typically weld between 3mm and 10mm of stainless steel, carbon steel, or aluminum, depending on power level. The thicker the metal, the higher the laser wattage you need.

Here’s what Kirin Laser recommends based on real test data:

Why thickness matters

It’s all about penetration depth⁵. Too little power, and you won’t achieve full fusion. Too much, and you risk burn-through. The right match ensures strength and visual quality.

From my own shop tests, a 2000W handheld model welded 5mm carbon steel⁶ flawlessly, producing smooth beads with almost no slag. On thicker plates, I noticed that adjusting travel speed was key. Unlike arc welding, you can control depth simply by slowing down slightly.

Real-world tip

For heavy fabrication—say, 8–10mm steel plates—a 3kW system like Kirin’s premium model is ideal. But if you mostly handle auto repair, stainless kitchenware, or thin sheet metal, 1500W is usually enough.

Can a laser welder cut?

Many people still assume that laser welders are only for joining metals. But the truth is, they can also do light cutting and trimming when equipped properly.

Yes, modern handheld laser welders like Kirin’s LightWELD can also cut thin metals. The same focused laser beam that welds can slice through steel, aluminum, and copper sheets up to 3–5mm thick.

How it works

When switched to cutting mode⁷, the system focuses energy into a narrow beam spot. The operator can follow a seam, edge, or contour line, and the laser melts the metal cleanly away. The result is a sharp edge with minimal burrs or oxidation.

From my perspective

When I first tried the cutting mode, I was surprised how easily it handled stainless seams. It didn’t replace a full-size CNC cutter⁸, but for field repair work, it was unbeatable. I used it to trim excess metal around welded joints—clean, fast, and without switching machines.

One customer even called it “the Swiss Army knife of metalwork,” and I couldn’t agree more.

Conclusion

After working hands-on with Kirin Laser’s LightWELD handheld system⁹, I can say it’s more than a welding tool—it’s a full metal-processing solution. You can weld, clean, and cut using one device, saving space, time, and money. For small to medium workshops, the ROI and versatility make it a solid investment. Match the power level to your production needs, and you’ll unlock precision in every beam—just like our motto says.
