How to Choose a Chinese Laser Welder Supplier (Buyer Checklist)
News 2026-11-10
The safest way to choose a Chinese laser welder supplier is to confirm five things before you pay: that it is a real factory, which laser source and welding head it uses, what the warranty covers, how support and spare parts work, and whether it will test your own material on video. This guide explains each check and the questions to ask.
1. Factory or trading company?
Many websites selling handheld laser welders are traders. A factory can control quality, lead time and spare parts. Ask for:
- The factory address and a live video tour of the assembly area
- Business license and year founded
- Monthly production capacity
- Photos of recent shipments packed for export
2. Key components
A handheld laser welder is mainly the fiber laser source, the welding head (torch), the control system and, for water-cooled models, the chiller. Ask the supplier to name the brand of each.
| Component | What to ask |
|---|---|
| Laser source | Brand and power (for example Raycus or Rlaser, 1500W / 2000W / 3000W) |
| Welding head | Brand and model (for example Suplaser or RelFar), wobble range, wire feeding support |
| Cooling | Air-cooled (no chiller, portable) or water-cooled (chiller brand and capacity) |
| Electrics | Brand of breaker, contactor and emergency stop |
3. Match power to your material
Ask for a parameter table and check it against the thickness you weld. Reference values used by our engineers for stainless steel, carbon steel and galvanized steel:
| Thickness (mm) | Suggested laser power (W) | Wire diameter (mm) |
|---|---|---|
| 1 | 400–500 | 0.8–1.2 |
| 2 | 450–600 | 1.2–1.6 |
| 3 | 500–800 | 1.2–1.6 |
| 4 | 600–1200 | 1.2–1.6 |
| 6 | 1200–2500 | 1.2–1.6 |
| 8 | 2000–3000 | 1.2–2.0 |
As a rule of thumb, a 1500W machine covers most work up to about 4 mm; for 5–8 mm choose 2000–3000W.
4. Warranty, support and spare parts
- Warranty on the machine and, separately, on the laser source
- Remote video troubleshooting and English manuals
- Spare parts list with prices, and how fast parts ship
- Who pays freight for warranty parts
5. Test with your own parts
Send drawings or samples of what you weld and ask for a welding video before you order. A confident factory will do this for free.
6. Terms for distributors and OEM buyers
If you plan to resell, ask about minimum orders, demo machines, territory, training and private label. Avoid suppliers who demand a large first order before you have tested the machine.
Checklist
- Real factory confirmed by video
- Component brands named in writing
- Parameter table matches your thickness
- CE documents received
- Warranty and spare parts in the contract
- Weld test on your material
- MOQ, lead time and payment terms clear

FAQ
Is it safe to buy a laser welder from a Chinese manufacturer?
Yes, if you verify that the supplier is a real factory, ask for CE documents, test the machine on video with your own material, and agree warranty and spare-parts terms in writing before payment.
What warranty should a laser welder supplier offer?
A typical factory warranty is 1 year on the machine; good suppliers give 2 years on the laser source, which is the most expensive component.
What is a reasonable minimum order?
Many factories, including XFH LASER, accept 1 set, so you can test one machine before ordering more.
How long does shipping take?
Standard machines from a stocked factory can ship within about one week; sea freight to Europe, North America or Australia then usually takes several weeks depending on the port.
