3. How about the warranty?

We have 2 years warranty and lifelong maintenance.


4. What is your terms of delivery?

We accept EXW, FOB, CFR, CIF, DDU, DDP, etc. You can choose the one which is the most convenient or cost effective for you.


5. Why is this unit called an “air-cooled all-in-one”? How does it differ from the water-cooled model?

This unit features an integrated air-cooling design that eliminates the need for an external chiller. It is a fully integrated, compact unit that is easy to transport. Compared to the water-cooled model, it saves space and reduces both equipment and maintenance costs, making it ideal for outdoor and mobile applications.


6. Is it easy for beginners to operate? Is it difficult to learn?

Operation is simple and requires no professional welding background. The equipment comes with comprehensive preset parameters, allowing you to start working immediately upon powering on. You can become proficient in a short time, significantly lowering the technical barrier for operators.


7. How is the welding quality? Will the workpiece warp or turn black?

The laser has a small heat-affected zone and high welding speed, so the workpiece is less prone to warping. The weld beads are smooth and aesthetically pleasing, with minimal blackening, resulting in less post-welding grinding work.


8. Can the equipment be used for mobile operations? Is it suitable for on-site construction?

The unit features a lightweight, integrated design that is portable and easy to move, requiring no complex installation. It is ideal for on-site welding at construction sites, outdoor repairs, and off-site processing.


9. Does the equipment have a high failure rate? How is it maintained on a daily basis?

The air-cooling system is simple and stable. The core laser light source has a long service life and requires few consumables. Maintenance is simple—just periodically clean the cooling vents and protective lenses—resulting in low operating costs.


10. What welding methods does it support? Can it weld irregularly shaped workpieces?

The handheld welding torch is flexible and lightweight, with adjustable angles, allowing it to handle irregularly shaped workpieces, hard-to-reach corners, joint seams, and edges—areas that are difficult for traditional equipment to weld—making it extremely versatile.
