A handheld fiber laser welding machine should be selected from the workpiece and production requirement—not from laser power alone. Material grade, thickness, joint design, seam condition, filler-wire requirement, workshop electricity, shielding gas and laser-safety controls all affect the correct configuration.
The QintelliM QMZN-FLW Series is a water-cooled industrial welding platform available in six nominal laser-output classes from 1000W to 6000W. The system includes a handheld welding head and wire feeder. It is designed for welding suitable metal workpieces; laser cleaning and cutting are not included in this product scope.
Higher nominal output does not automatically mean a better welding result. A useful configuration review starts with five questions:
Two workpieces made from the same material can still require different settings because their thickness, joint access, surface condition and heat behavior are different. Photos, drawings and representative samples help the supplier review the application before the final model is selected.
| Model | Nominal Laser Output | Typical Power Supply | Selection Note |
|---|---|---|---|
| QMZN-FLW-1000 | 1000 W | 1Ph 220–240V / 50Hz | Lower-power configuration; final suitability depends on the application. |
| QMZN-FLW-1200 | 1200 W | 1Ph 220–240V / 50Hz | Higher nominal output than the 1000W model on the same platform. |
| QMZN-FLW-1500 | 1500 W | 1Ph 220–240V or 3Ph 380–415V / 50Hz | Electrical configuration is confirmed for each order. |
| QMZN-FLW-2000 | 2000 W | 1Ph 220–240V or 3Ph 380–415V / 50Hz | Single- or three-phase configuration is confirmed for each order. |
| QMZN-FLW-3000 | 3000 W | 3Ph 380–415V / 50Hz | Higher-output three-phase configuration. |
| QMZN-FLW-6000 | 6000 W | 3Ph 380–415V / 50Hz | Highest nominal output in the current range; site electricity and cooling must be reviewed carefully. |
These values identify the available power classes; they are not a universal material-thickness guarantee. The correct model should be confirmed through a review of the actual workpiece, joint and required result. When the application is demanding or the acceptance criteria are strict, sample welding is recommended before the order configuration is approved.
Available fiber laser sources may include BWT, Everfoton, Maxphotonics or a technically compatible customer-specified equivalent. The selected laser-source brand and model should be recorded in the final quotation and technical specification.
Typical candidate workpieces may include stainless steel, carbon steel, galvanized steel and aluminum alloy. Final suitability depends on more than the base material name. The exact grade, thickness, coating, surface condition, joint fit-up, shielding gas, filler wire and required weld result must be considered together.
For example, the same nominal power may behave differently on a thin stainless-steel enclosure, a carbon-steel frame and an aluminum component. This is why material samples and joint drawings are more useful than asking only, “How many millimeters can the machine weld?”
The wire feeder supports filler-wire welding when the seam gap, joint geometry or required weld profile makes filler wire appropriate. It does not mean that every job should use filler wire. The wire material and diameter must match the workpiece and welding process.
Shielding gas may be nitrogen, argon or helium according to the application. A typical process pressure is 0.25–0.30 MPa, but the final setting should follow the approved welding procedure.
The system is water-cooled. High-quality pure water or distilled water should be used, and the cooling circuit must be maintained according to the delivered manual. The product platform is intended for an indoor industrial environment with stable electricity, ventilation and controlled laser access. The recommended ambient temperature stated for the current QMZN-FLW platform is +5°C to +33°C.
A handheld fiber laser welding machine is high-power industrial laser equipment, not a conventional handheld electric tool. The equipment and workplace must be evaluated as one system before production starts.
The final safety plan may include trained and authorized personnel, controlled access, suitable laser protective eyewear, barriers or an enclosure, door or process interlocks, emergency-stop functions, fire precautions, correct grounding, warning signs and appropriate ventilation or fume extraction. The exact safeguards depend on the delivered machine, the installation and the rules that apply at the destination.
Buyers should therefore confirm local workplace and laser-safety requirements before ordering. If a safety cabin, hold-to-run device, special interlock logic or destination-specific documentation is required, it should be written into the technical agreement instead of being assumed after delivery.
Voltage, phase and frequency must be agreed before production. The laser-source brand and model, installed components, machine dimensions and weight are also order-specific and should appear consistently on the quotation, technical specification and machine nameplate.
The QMZN-FLW product page includes a UDEM Attestation of Conformity for the laser welding machine family. For the delivered machine, buyers should still review the order-specific declaration, nameplate, operating instructions, electrical information and safety documentation required for the destination market. A certificate image alone should not replace a complete technical review.
This information allows the supplier to review the power class, electrical configuration, laser source, wire-feeding setup, utilities and documentation as one project.
No. Power must be matched to the material, thickness, joint, required result and production target. Oversizing without reviewing the application can create unnecessary cost and site requirements.
Yes. A wire feeder is included for applications that require filler wire. The appropriate wire material and diameter are confirmed according to the workpiece and joint.
No. The current QMZN-FLW product scope is welding only. Cleaning and cutting functions are not included unless a separate confirmed product and technical agreement state otherwise.
The requirement depends on the selected power class. Lower-output models typically use 220–240V single-phase supply, while the 3000W and 6000W models use 380–415V three-phase supply. The final voltage, phase and frequency must be confirmed in the order.
The required machine configuration and document package must be reviewed for the destination country and installation. Buyers should provide their safety, workplace and documentation requirements before the technical agreement is finalized.
