80% duty cycle at rated current is what actually matters here, not just peak output — a 500DP model holds 500A steady for eight minutes out of ten without tripping thermal protection, and we’ve had welding shops push it to 450A continuously for full on thick plate with water cooling plumbed in.
Teh CPU+DSP control system handles pulse waveforms in real time, and that double pulse feature reduces spatter noticeably — usually around 30-40% less post-weld cleaning compared to traditional MIG sets — so shops welding thin-gauge car body panels or yacht hulls get decent bead appearance without switching to TIG, but you wouldn’t use it for heavy gouging below 30A output range anyway.
Insulation class H winds the main transformer for higher heat tolerance, and the push-pull wire feeder option clears 15-meter torch lengths without birdnesting, which is handy for pressure vessel work where you’re crawling around corners — most buyers go with the air-cooled 350DP unit for portable repair work, give or take, because the 152kg water-cooled cabinet is honestly a pain to move between bays.
Input voltage is AC380V three-phase ±10%, 50Hz — no single-phase adapter available on these models, so check your shop floor wiring before ordering — and output current range straddles 20-350A for the 350DP or 25-500A for the 500DP, with output voltge ramping from 14V up to 40V or 50V respectively, which covers MIG on 12-gauge sheet all the way to pulse welding 1-inch aluminun.
Lead time for the 350DP air-cooled variant is usually 14 working days or so, but the 500DP with water-cooled chassis can stretch to 5 weeks because they hand-assemble the radiator packs — we keep a handful of stock in warehose but confirm before ordering for large quantities; the 4 custom parameter storage slots you can name in the panel are standard on both models, and that alone saves re-dialing settings when switching between steel and aluminum.
Our standard MOQ is 1 unit for stock models, but we can negotiate larger quantities for custom orders. Lead time for a single unit is typically 15–20 working days; bulk orders may take 25–35 days depending on the configuration.
Yes, we can supply CE and ISO certifications upon request. We also include a test report and wiring diagram with each machine to help with compliance and installation.
Absolutely. The welder lets you save up to 99 custom parameter sets, so you can recall your favorite settings for different materials or joint types without dialing everything in again.
The air-cooled model weighs 42kg (350DP) or 52kg (500DP) and measures 640x320x590mm, while the water-cooled version weighs 142kg or 152kg with a much larger footprint of 1130x600x1410mm. Choose water cooling if you need higher duty cycles or longer continuous welding.
You adjust the regulator on your gas cylinder to between 15 and 20 L/min as specified. The machine itself doesn't have a built-in flow meter, so you'll need an external regulator—we can include one in the package if you need it.
