AC inverter welding power supply
AC inverter type do not have a blank-period created from the phase control by thyristor. Unlike the single-phase AC type, the temperature at the wielded spot will not be leapt up intermittently to have a high peak temp. Instead, it continuously and gradually increase and the power supply type shows a good thermal efficiency, which allows it unified heating suppressing the peak current. Hence, high quality and expulsion-less, stable welding can be achieved.
An inverter type welding power supply and a weld checker (MM-370A with displacement option) are connected, and displacement amount at the electrode (penetration amount) is set in the weld checker. When the displacement amount reaches the set level, a signal will be sent out to trigger the interrupt function, and stops the current. This enables the fusing with stable displacement.


The MIB-200A is the ideal welding power supply for coated wire welding and electrical parts fusing. The teaching technique using an optional, MA-627A, has been employed for the setting method. The weld-time can be set by the unit of cycle.
* Fusing is a terminal processing method that vaporizes the coating of coated wire with heated pressing welding and bonds the wire core to the terminal.

AC inverter welding power supply
Since registered weld schedule can be loaded with one key operation, work efficiency has been improved.
Actual weld current is monitored so as to ensure it to stay in the preset range.
1000A: 100 to 1000A
3000A: 300 to 3000A
The MIB-70B is the ideal welding power supply for precision welding of small parts. All the setting can be done directly on the pannel of the power supply unit, and the timer setting can be configured by a unit of mili-second.
