Import Dw Series Cam Type Butt-Flash Welding Machine — Buy in Bulk from Supplier in China

The Dw Series Cam Type Butt‑Flash Welding Machine is a stationary unit that joins metal workpieces by flash heating and pressure. It is offered in six models - UN‑5050, UN‑7575, UN‑100100, UN‑150150, UN‑200200 and UN‑250250 - with rated powers ranging from 50 kVA to 250 kVA. Each model operates on 380 V/420 V three‑phase supply at 50 / 60 Hz, delivers a maximum short‑circuit current of 19 kA to 52 kA and maintains a 50 % duty cycle. The machines provide up to 4 000 N clamping force and up to 12 000 N upsetting force, weigh between 350 kg and 1 800 kg, and fit within dimensions of 100 × 90 × 150 cm to 180 × 120 × 190 cm.

The equipment is designed for welding steel, stainless steel and aluminium alloys, with a cam‑type mechanism that ensures repeatable jaw alignment. Typical flash‑butt welding systems require a water‑cooled transformer and a minimum cooling water flow of 15 L min⁻¹, which this series can accommodate. Industry practice specifies a voltage tolerance of ±5 % and a current ripple below 2 % to achieve consistent weld quality, both of which are supported by the machine’s control electronics. The machines comply with common safety standards such as IEC 60204‑1 for electrical equipment and are built to endure at least 1 000 operating cycles per day.

Typical users include manufacturers of dinnerware, cutlery, bicycle and motorbike rims, construction steel bars and custom‑fabricated tube structures. Buyers should confirm the required power infrastructure, water‑cooling capacity and any local certification needs before placing an order.
