The number one selling and most advanced
Mid-Frequency DC (MFDC) inverter weld control on the market today.
These controls are available in capacities from as low as 1000 to over
140,000 secondary amps. Since these MFDC controls are 3 phase
devices, the electrical demand from the power system is about 40% that of
single phase AC welding.
-
The user has the ability to program weld time in 1
millisecond increments to fine tune their welding process. The
smallest resolution of adjustment using single phase AC is over 16
milliseconds (for 60Hz power systems).
-
Since there is no latent cooling time between
cycles like there is with AC welding, current magnitude and welding times
are generally less with DC current than with AC current.
-
The new Ultrasonic Quality System module option
for the MFDC systems can virtually assure that all welds will be quality
ones or the system will fault the machine out so that the operator may find
out why.
-
With the addition of an analog proportional air
valve, the Bosch weld control can control the weld force directly and even
make up to 9 weld force changes in real time during execution of the weld
schedule.
