B: To set the maximum current automatically, from the measurement of actual welding
If the maximum current of the welding machine is unknown, set the maximum current
automatically with the automatic setting function.
Connect the toroidal coil (sold separately) to the
MEA-100B
.
To display the #1 of the SET1 screens, press the [MENU] key and the [

Description
Setting Range
a
Squeeze time.
The set squeeze time must be longer than the actual
squeeze time. (HLD (hold time) will equal SQ (squeeze
time).)
00–99 cycles
b Weld time.
The set weld time must be the actual weld time.
01–99 cycles
c
The set current must be 60% to 90% of the actual welding
current in order to prevent the damage to the
MEA-100B
caused by overcurrent.
0.20–9.99 kA
d Weld Force number. Select the welding machine for which
you want to set the maximum current automatically.

Close Terminal 28 ([START(1ST)]) of the I/O Terminal Strip on the rear panel.
After test welding is complete, the display will revert to the screen shown in
.
The screen shows the maximum current set automatically.
If the display does not revert to the screen, repeat test welding until the screen returns.
(To measure the maximum current, welding must be performed for 6 cycles.)
Caution: Moving to another screen during the automatic maximum current
setting will interrupt the setting process.
Caution: The value set by the automatic setting function is an approximation.
Sometimes the value is differrent from an actual maximum current.
Do not use this function other than the setting of the maximum
current.
