It's a real headache when you've got thick aluminum or presure vessel steel that needs perfect welds every time, and standerd machines just can't handle heat control or arc stability without spatter and warping.
So what it does is use a full digital CPU+DSP control system to keep the pulse waveform tight and consistent, even when the voltge dips or the wire feed gets a little rough—basically, you get cleaner beads and less post-weld cleanup, which saves hours on a big job.
The 500DP model pushes up to 500A and 50V for heavy plate, but the 350DP is more manageable at 42kg or so for air-cooled setups, while the water-cooled version weighs 142kg and needs a cart or fixed station; both run on AC380V with an 80% duty cycle, and the insulation class is H, so it handles sustained use better than most industiral units.
2T, 4T, special 4T, and spot welding modes are all in there, and the gas flow rate typically sits at 15-20 L/min for aluminum—we usually keep the 350DP in stock, but the 500DP water-cooled variant has a lead time of 20 days or so (check availability).
You can also use it for arc gouging or TIG if needed, but honestly, it's not great for thin sheet metal under 3mm because the pulse settings are optimized for thicker material, so don't expect perfect results on car body panels.
Anyway, the 350DP air-cooled version is roughly 640×320×590mm and comes with a push-pull wire feeder, which is easier to handle for alumnum than push-only systems, though the 500DP water-cooled unit at 1130×600×1410mm is a different beast entirely.
The MIG-350DP maxes out at 350 amps, while the MIG-500DP goes up to 500 amps. Keep that in mind when choosing for thicker materials like pressure vessel steel or heavy aluminum.
Yes, it holds CCC, CE, ISO, and ROHS certifications, so you're covered for most international quality and safety standards. We can provide copies upon request.
Our MOQ is typically 1 unit for stock models, but for the water-cooled 500DP (142kg version), we recommend ordering at least 2 to split freight costs. Lead time is around 15-20 working days.
Absolutely. The MIG-350DP/500DP supports push-pull wire feeding, which is ideal for soft aluminum wire. Just set it to pulse MIG mode and adjust gas flow to 15-20 L/min for best results.
Both models run at 80% duty cycle, meaning you can weld at full power for 8 minutes out of a 10-minute cycle. For the 350DP air-cooled version, that's 350A at 40V before it needs a break.
