Capacitor discharge type power supplies provide very short welding times. These limit the chance of burning or deformation of the part and allows repeatable welding of small parts.

  • Welding is interlocked and will not engage if the charged voltage does not reach a preset value.
  • The capacity of the condenser bank can be switched to other levels. (50% or 100%)
  • Three kinds of welding wave forms can be set.
  • A counter with preset functions is built into the system.
