We needed something that could handle stainlss and aluminum on the same day without switching machines, and DA-HW pretty much covers that with the 1000W to 3000W range — we went with the 2000W for our shop since it handles up to 8mm on most materials we see.
The welding speed is roughly 4x faster than TIG, which actually matters when you're running back-to-back jobs on thin sheet and need to keep the heat input low, and the 1-5mm swing width adjustment gives us enough control to avoid burn-through on 1.2mm alumnum without having to swap tips.
Water cooling is built in, so you don't have to rig up an external chiller, and the fiber length we ordered is 10m which is usually enough for our work area but if you're moving around a large part you'll want the 20m option (check lead time on that one).
It's not really suited for heavy strucutral welding over 8mm plate, so if that's your main use case you should look at a separate gantry system, but for most fabrication shops doing repairs or custom work this is better than buying three separate machines.
One thing most buyers don't think to ask is that the 1064nm wavelength means you can clean rust off before welding without changing heads — we've used it to prep a joint and then weld in the same setup, which cuts setup time by about 20 minutes per job.
Anyway, we ordered the AC380V version since our shop runs on three-phase, and the 3-year warranty was a factor given how much we'll be running it — the COA form the last batch showed consistent power output within 5%, which is tighter than some competitor units we tested.
Right now we offer 10m and 20m as the standard fiber lengths. We can't do custom lengths in between, but the 20m option gives you plenty of reach for most workshop setups.
Each unit ships with CE and FDA certifications, plus a factory test report. If you need a specific certificate for your country's import requirements, just let us know and we'll check what we can provide.
For the 3000W model, the MOQ is 1 unit. Same goes for all power options—you can order just one machine to test it out.
The 1000W version runs on AC220V single-phase. The higher power models like 2000W and 3000W require AC380V three-phase, so make sure your shop has the right power setup before ordering.
Keep it in a dry, clean area between 5°C and 40°C. Make sure the water cooling system is drained if temps might drop below freezing, and cover the laser head to protect the lens from dust.
