Resistance Welder DC Capacitor Model NRW-DC150A

The NRW-DC150A is a resistance welding machine providing direct current (DC) output via a capacitor discharge design. The unit is typically used in combination with a hand-held or automated welding head for joining connecting semiconductor lead frames and capacitor hoop materials. The weld is made when energy stored in the large-capacity capacitor is instantly discharged to the welding head for welding.

Features

  • Dual Pulse Function: reduces weld spark and improves quality
  • Multiple Materials: suitable for aluminum, copper and other weld materials
  • Short, Concentrated Energy Burst: reduces deformation and burning
  • Fast Charge Time: improves productivity (welding speed 75W･S. 120 shots/min)
  • VS (Very Short) Mode: obtain peak welding current equivalent to a 200W･S type model
