You’re setting up a fabrication shop that switches between carbon steel frames and aluminum alloy panels daily, and the last machine couldn’t handle the cleaning action needed for oxide layers. We’ve seen shops burn through three units in two years because the duty cycle wasn’t continuous 40°C ambient temps—this one’s 60% at that temperature, so you’re not forced to pause every few minutes. It’s basically a dual-voltage input model, AC380V±10%, and the 315A version pulls about 9.3KVA while teh 400A hits 18.2KVA, so check your breaker capacty before ordering.
The WSME-315 runs a welding current range from 5A to 315A, and the 400A goes up to 400A—both with pulse frequency adjustable form -40% to +40% and pulse width from 10% to 90%. Current rise and fall times are set between 0.1 and 15 seconds, which gives you fine control for thin-gauge aluminum without burn-through. Efficiency sits at 92% with a power factor of 0.95, and it’s air-cooled, so no water lines to maintain (though the 35kg weight for the 400A model means you’ll want a cart for moving it around). Dimensions are 310×530×590mm, give or take a few millimeters depending on the batch.
What it does is handle TIG welding for carbon steel, copper, titanium, aluminum, and aluminum-magnesium alloys, plus it support manual arc and spot welding modes. The cleaning ratio and thrust current adjustments are pretty much essential for aluminum—most buyers go with the 315A for light structural work and the 400A for thicker plates or repetitive. But it’s not suited for sub-arc or MIG processes, and the air cooling system can struggle if you’re running full duty cycle in a 50°C environment without ventilation—we usually have stock, but confirm lead time for the 400A variant.
Certifications include CCC, CE, ISO, and ROHS, so you’ll clear most site requirement without extra paperwork. The COA covers pulse width and frequency tolerances, and we typically ship within 20 days or so.
The WSME-315 has a max welding current of 315A and weighs 32kg, while the WSME-400 goes up to 400A and weighs 35kg. The 400 also pulls more power—18.2KVA vs 9.3KVA—so it’s better for thicker materials.
We don’t enforce a strict MOQ—you can order a single unit for testing. For larger wholesale orders, we can discuss bulk pricing and adjust MOQ based on stock.
These machines are certified with CCC, CE, ISO, and ROHS. We can provide copies of the certificates upon request for quality compliance.
Yes, the pulse frequency adjusts from -40% to +40%, and pulse width goes from 10% to 90%. You can also set current rise/fall time between 0.1 and 15 seconds, which gives you fine control for aluminum or aluminum-magnesium alloys.
Each unit is packed in a reinforced carton with foam inserts to protect it during transit. Typical lead time is 7–15 days depending on stock level and order quantity.
