When they're welding 20mm alumnum plate for presure vessel seams, the pulse control on this thing actually makes a visible difference in bead consistency—especially compared to older transformer-based units where you'd fight with arc wander on every pass.
We've seen shops running the 500DP at 350A on steel for eight-hour shifts with no overheat trips, teh 80% duty cycle at 40°C is pretty much what it says, and the dual cooling option means you pick air for portability or water for sustained high-amp work on marine hulls (usually 4-6 weeks on the water-cooled lead time).
The push-pull wire feed handles aluminum wire up to 1.6mm without birdnesting, which is the main thing that kills productivity on long gun setups, and the parameter storage lets you recall a 15mm stainlss groove weld profile in seconds.
One limitation—it's not ideal for thin gauge sheet metal below 2mm unless you dial back the inductance manually, the arc stays too hot even at the low end of the 25-500A range.
CE and CCC certs are on every unit, we send COA with HPLC purity specs for the gas flow components if you request it (most buyers don't ask but it's useful for process validation), and the IP21S rating means it tolerates shop dust but not standing water.
Actually, the water-cooled version is about 60% heavier than air-cooled at 152kg—something to budget for if you're moving it between workstations on a cart rather than bolting it down permanently.
MOQ is typically 1 unit, and yes, you can mix air-cooled and water-cooled variants in a single order. Just specify the quantities for each model.
Standard lead time is around 25-30 working days for that quantity, but it depends on current production schedule. We can confirm once you place the order.
Yes, we include CE and CCC certificates with every shipment. Both are fully compliant for EU and Chinese customs clearance.
The 80% duty cycle is rated at 40°C ambient temperature for the maximum rated output current—500A for the 500DP. So it's tested at full load, not just lower settings.
The water-cooled version comes with the integrated water cooling system built into the machine—no need to source separately. It's all included in the unit price.
