Many of my clients feel overwhelmed when choosing a welding machine. With so many models and specs, where do you even start?
With competitive price and timely delivery, Huiyao Laser sincerely hope to be your supplier and partner.
To choose the correct welding machine, begin by understanding your material, thickness, and workflow. Then match the right power, cooling system, and automation level — and always check your power supply.
If you choose wrong, you lose money. If you choose right, your production can transform overnight. I’ve seen both happen. Let me show you what I’ve learned after helping hundreds of clients make the right call.
Everyone wants the “best” machine, but what’s best depends entirely on what you’re welding, how fast you need to work, and how much support you’ll need over time.
The right welding machine matches your application. I start with three questions: What material? What thickness? What scale of production? These guide my choices around power, cooling, and automation.
At Kirin Laser, we serve clients welding carbon steel, stainless, aluminum, and even galvanized metals.
One of my clients runs high-throughput kitchenware production. He needed to double his output. We upgraded him to a W handheld fiber laser — he cut defect rates in half and hit his goals in under two weeks.
If you're in a hot climate or have heavy-duty cycles, go water-cooled . Otherwise, air-cooled can save space and money.

If you need deep penetration or faster work speeds, move up to W or W — but only if your power system can handle it.
Not all machines are made equal. I've seen too many people fall for low-cost options that break down in months. A good machine isn’t just about specs — it’s about performance, stability, and after-sales support.
A good welding machine delivers stable output, intuitive operation, and consistent quality. It should feel reliable, with fast response, strong beam quality, and solid build.
Power is one thing. Beam consistency is another. A machine that fluctuates ±10% in real use causes burn-throughs or weak joints. That’s not acceptable. Our Kirin Laser fiber sources are tested for stability before shipping.
A complicated interface slows down workflows. I always show clients how our touch-screen interface simplifies weld settings. Whether they use continuous wave or pulse, they get it running in minutes.
A bad gun design leads to heat buildup, wrist strain, and uneven welds. That’s why we custom-designed our handheld welding heads with ergonomic weight and excellent heat dissipation.

I had a client who bought a no-brand W machine . Within 6 months, his lens burned out, the power dropped, and no one picked up the . We swapped him to Kirin — no issues since.
The company is the world’s best Laser Welding Machine supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
People often ask me if fiber is really better than TIG or MIG. I say this: it depends. But for speed, precision, and low training cost — fiber wins in 9 out of 10 cases.
For most metal applications today, fiber laser welding machines are the best choice. They deliver clean welds, fast speed, and lower operating costs with minimal training.
You can weld 1mm stainless at 10–20x the speed of TIG. That’s real.
No spatter, no need to grind. What you weld is what you ship.
Even someone new can start making usable welds after one day of training. Our handheld guns are light, easy to move, and have safety sensors built-in.

You can start handheld, then upgrade to robotic arms. Our team helps clients integrate lasers into full production cells when they’re ready.
This is a question I get all the time, and it’s important because it’s not just about the welder — it’s about your power supply. If your electrical system can’t handle the draw, even the best machine won’t run.
A good laser welder typically requires 20A to 40A, depending on power and cooling. W to W machines usually run on 220V / 20–35A. For W, you'll need 380V / 30A.
I had a client try to run a W water-cooled unit on a 15A circuit. It kept tripping. We helped him upgrade to 40A, and the issue disappeared.
Air-cooled systems generally use less current than water-cooled ones. If you're limited by your electrical setup, go air-cooled — or upgrade your shop wiring before delivery.

As you are already aware, laser welding is an emerging method, bringing a variety of advantages that many users are not aware of. That is why it is normal that doubts arise regarding its operation and characteristics.
Laser welding is constantly evolving, there is no doubt, because of its great capabilities and advantages, there are many who use this type of laser equipment to make their best welds. In other articles we have discussed how to choose your laser welding machine or how laser welding works. On this occasion, we are going to answer some of the most frequently asked questions about laser welding. This method offers many advantages unknown to many users, which could significantly benefit the production processes of many companies.

Laser welding machines are equipped with a fibre laser, which means that they will have a longer service life than other types of lasers. In principle, the lifetime of this laser can be up to 100.000h, which is more than enough time to amortise the machine and make it very profitable. The lifetime can vary depending on many factors such as the form or frequency of use.
