So you’ve got a customer who needs to weld thin-gauge stainless steel battery casings for EVs or alumnum enclosures for electronics, and they’re pushing for faster cycle times than TIG can handle—that’s where this lands. We’ve been running the 1500W version for about six months now on automotive sensor housings, and the wobble head with adjustable 0.2-5mm spot size lets us dial in penetration without burning through thin walls.
The laser source is either Raycus or MAX, both are solid for continuous wave operation, and we usually stock the 1000W and 2000W models—the 3000W is better for thicker plate but overkill for most electronics work. Wavelength is 1080nm ±5, which is pretty standard for fiber lasers, and the 10m fiber cable gives decent reach around a workbench or small fixture. Power consumption runs about 7.5-10KW depending on output, so make sure your shop has 220V or 380V avaliable—voltage tolerance is ±20% which is forgiving.
Cooling is water-based with a 1.5P to 2.5P chiller, and honestly, for continuous runs over 4 hours you’ll want the 2.5P unit or system will throttle down. The protective lens is D20*2, and we had to replace one after about 300 hours of welding with heavy spatter on copper—so factor that into consumables cost. CE compliant, three-year warranty, but the real test is the wire feeder: 25-600cm/min feed rate, and it handles 0.8-1.2mm wire without jamming if you keep the tension right.
Welding head options are Qilin, SUP, or WSX—we went with SUP because of that it’s easier to swap nozzles for different patterns (dot, line, circle). Spot size adjustment is smooth, but you’ll need to calibrate it against matrial thickness; we usually run 1.5mm spot for 1mm stainless with argon shielding gas. One thing nobody mentions: the machine weighs about 250kg, so you’ll need a pallet jack or forklift for positioning—it’s not a benchtop unit.
Also, it’s not great for very thin foil under 0.3mm unless you drop power below 500W, which isn’t really this machine’s sweet spot—you’d be better off with a pulsed laser for that. But for general metal fabrication, automotive brackets, or electronics chassis welding, it’s faster than TIG by a factor of 3-4x on most joints we’ve tested. We usually have stock on the 1000W and 1500W models, but confirm lead time on the 3000W—it’s typically 20 days or so from order.
We do offer samples for evaluation; the MOQ for the KW-M series starts at 1 unit for standard models, but custom specs may require a higher minimum.
Lead time is typically 15-25 working days for standard configurations, depending on stock of the Raycus/MAX laser source.
Yes, every KW-M series unit ships with CE certification and full test reports. We can also provide material certificates for the protective lens and fiber upon request.
Absolutely. The KW-M supports Qilin, SUP, or WSX welding heads as options. You can switch them based on your job—Qilin for precision electronics, WSX for heavy auto parts.
Store it in a dry, dust-free area at 5-40°C, and drain the water cooler if temps drop below freezing. It runs on 220V or 380V ±20%, so check your shop power before setup.
