The SPATZH300plus high-frequency inverter power
source with its 20,000 Hz clock frequency is the allpurpose,
cost-effective alternative to all of the transistor-
controlled power supplies for micro welding and
small component welding. With its rapid reaction
speed, the SPATZH300plus displays highperformance,
lasting welding capability, functioning with
just as much precision at 100 A as it does at 9,000 A.
Each welding operation is feedback controlled during
the procedure. The control process takes place very
quickly based on the 20 kHz inverter frequency. Actual
values are compared with target values every
0.025 ms. The output power is adapted during the
welding process if targets are not being met. Constant
Current Control (CCC), Constant Power Control (CPC)
and Constant Voltage Control (CVC) can all be used.
At the end of each weld, the SPATZH300plus checks
whether the actual welding parameters keep within the
The SPATZH300plus’ timer and high-frequency inverter
are housed in a compact IP54-protected housing,
which weighs a total of 30 kg / 66.1 lb. While the external
high-frequency transformer needs to be installed
close to the welding site, the SPATZH300plus can be
installed within the vicinity of the machine.
The SPATZBG-02 operating device is used for operating
the functions and adjusting the welding parameter
settings. The curve characteristics of the process signals
and the measured values of the last 10,000 welds can
be read by the SPATZBG-02 at any time.
The specific advantages of the SPATZH300plus highfrequency
inverter, such as its low weight and high output
voltage, allow the easy system integration. The high
output voltage enables relatively long welding power
lines to lead to the welding position.
The SPATZH300plus high-frequency inverter is
deliverable for a mains input voltage range from
3~400 V to 500 V.
