The W series tubes increase in physical length and aperture as power goes up. The W2 is 1240 mm long, the W4 is 1450 mm long, and the W6 is 1650 mm long. Larger length means a larger gas volume at higher pressure, which is what enables more output. RECI also assigns them different power supplies. The W2 ships with a DY13 supply and the W4 and W6 ship with a DY20 supply. Beyond that, all three use the same TEM00 above 95% beam mode and the same 10,600 nm wavelength, so cut quality at equivalent settings is comparable. The higher-power tubes simply cut faster or cut thicker.

RECI tubes have a rated power and a peak power. The W2 is rated at 90W and peaks at 100W. RECI guarantees the rated power on every tube and most tubes reach somewhere between rated and peak in actual use. We market the range honestly because it reflects what you can expect to see at the cutting head. Some marketing on competing machines lists only the peak power, which is misleading.

Yes. The same machine handles raster engraving on wood, leather, acrylic, anodized aluminum (coating removal only), and many other CO2-compatible materials. Maximum engraving speed is 1000 mm/s with locating precision below 0.01 mm. The minimum shaping character is 2 x 2 mm and minimum letter is 1 x 1 mm. For dedicated high-speed engraving on small parts, a CO2 galvo machine is faster because it scans with a mirror system instead of moving a gantry. The 1390 is the right machine when your work needs cutting and engraving on the same large flat material.

Yes. The S&A CW-5200 industrial chiller, chuck rotary attachment, both worktables (honeycomb and aluminum blade), 012 air pump, 550W exhaust fan, and all standard tooling are included in the listed price for all three variants. You do not need to purchase or source any of this separately. Software is RDWorks at no charge, with optional LightBurn license sold separately by LightBurn Software.

The Ruida 6445G has a built-in WiFi module that joins your shop's wireless network. From RDWorks or LightBurn on your design computer, you can send the job file to the controller over the network and start the job from the machine's panel. No USB stick. Particularly useful when the design computer and the laser are in different rooms. The USB port still works as a backup if WiFi is unavailable.

For United States, Canada, and European Union buyers, shipping is free DDP. Total time from order to delivery is approximately 30 days. DDP means we cover all import duties and customs handling. For other regions, we ship CIF with all import duties paid by the buyer. CIF transit is approximately 12 to 14 days plus your local customs clearance time. The machine ships crated and palletized for freight forwarder delivery.

The motorized Z-axis sits on a thick brass lead screw, not a budget threaded rod. The auto focus routine lowers the laser head until a contact probe touches the material surface, then raises the head by the focal distance of the lens. The result is the laser focus sits exactly on the surface every time without manually inserting a focus gauge. You set the focal distance once for each lens you use and the controller remembers it.

Yes. The included chuck rotary mounts inside the bed and is recognized by the Ruida controller automatically. It handles glass bottles, wood mugs, leather sleeves, and large cups. For tumbler-scale production work specifically, a dedicated CO2 galvo machine is generally faster because the galvo scanning head moves at higher speeds than a gantry. The 1390 with rotary is the better choice when you need both occasional cylindrical work and large flat sheet cutting on the same machine.
