Capacitor Discharge (CD) Stud Welder - CDMi 3202

The CDMi 3202 is an inverter-capacitor Capacitor Discharge stud welder designed for thin sheets from 0.5 mm and automated production. It provides selectable 3,200 Ws or 1,600 Ws welding energy, stepless charging from 50–220 V, and welding times from 1–3 ms. Supporting mild steel, stainless steel, aluminum, and brass, it reaches up to 43 studs/min on M3/#4 studs.
