FAQ
Q: What is the warranty on the LW-40D?
A: One year on the full unit, two years on the laser source. We ship replacement parts and support you by video.
Q: Can it weld aluminum and galvanized steel?
A: Yes. Use pulse mode and the right power range. For aluminum, add the anti-reflection option to protect the lens.
Q: What thickness can a 1200W handheld laser welder handle?
A: About 1–8 mm depending on material and joint type. With a wire feeder you reach the upper end.
Q: Do you offer a wire feeder?
A: Yes. Tell us your material and thickness and we will send matching specs.
Q: Air cooling or water cooling - which should I buy?
A: Air cooling if you move the machine often or run light to medium work. Water cooling if you weld heavy plate all day.
Q: What is the input voltage?
A: 220 V AC, 50/60 Hz. We can adjust for your market on OEM orders.
Q: Can you put our logo and language on it?
A: Yes. OEM/ODM on logo, touchscreen language and nameplate.
