2. Features
The IP-400B is an inverter-type small-sized precision resistance welding power supply
which has a constant-current control function applicable any workpiece and which
realizes high weldability and operability.
Sixty-three (63) types of welding schedules can be registered
Once a welding schedule is registered, it can be invoked by one key operation only.
When the welding schedules which will be used frequently are registered, you do not
need to enter the schedules each time when you operate.
Welding schedules can easily be set with four (4) keys
No troublesome operation is requested at all. Setting of the welding schedule is done
by means of four keys only.
Automatic switching of screen display
Normally, monitor panel displays the settings of welding schedules. However, the
display will automatically be switched to the monitoring values of the current when
welding current flows.
Good-looking and easy-to-see screen display
Because high-intensity LCD (Liquid Crystal Display) is employed, the display can be
seen clearly even in the gloom.
Sheet panel is sufficiently resistive to dust and oil mist
Stain can be removed very easily and therefore clean external view can be
maintained for a long time.
Monitor facility is helpful for stable quality control
IP-400B monitors welding current.
When actual welding current is beyond the monitoring range setting, then error signal
will be output to inform the user of occurrence of abnormal welding promptly.
Data control by external communication function
The external communication function allows the central control of IP-400B’s data
such as schedules and monitor values.
