Thanks for RFQ, we've got these in stock now and can ship within a week or so. The welding gun head handles M3 to M10 studs with a welding speed of 25-30 pieces per minute—that's consistent across stainles, carbon steel, aluminim, brass, and galvanized materials.

Adjustable charging voltage form 20 to 190V gives you control, and the welding time is just 2-5ms per cycle. We usually recommend it for plate thicknesses between 0.5-5mm, though it'll handle up to 5mm maximum on good day. Stud length range is 5-210mm.

One thing buyers often ask about is the 220V/50Hz input—make sure your line condition is clean, we've seen minor fluctuations affect consistency on thinner stock. It's CE certified, so compliance isn't an issue for most European setups.
Packaing is in protective boxes, five units per carton (34x34x34cm), and we include COAs with every batch. Most buyers go with the 5-piece MOQ, but our company can do single units if you're testing a prototype run.

Origin is China, HS code 8515900090, and we usually have a 3-5 day lead time on orders under 50 units. Let us know if you need a sample head sent before committing to the full lot.
The MOQ is one carton, which contains 5 pieces. For larger bulk orders, we can discuss volume pricing.
Lead time is typically 15-20 working days for standard bulk orders. If you need faster delivery, let us know and we'll check our stock.
Yes, the CE certification covers the entire unit, including the adjustable voltage from 20V to 190V. It's verified for safety and performance across the full range.
Yes, it can handle M3 studs down to 0.5mm plates, including stainless steel. Just make sure the charging voltage is set correctly for that thickness.
Each unit comes in a protective box, and 5 of those boxes fit in a 34x34x34cm carton. Store them in a dry place at room temperature to keep the components in good shape.
