/MAG welding
1.
Check that the welding conditions are correctly set and operate the torch switch to start the welding. (
6.6.3
-
Crater setting)
B
During the welding, the welding current is displayed on the left digital meter and the welding voltage is
displayed on the right digital meter both in a real time basis. This indication is the average value of the output per
approximately one second.
B
During the welding, the “Welding time”, “Heat input”, and “Motor current” are displayed on the LCD panel in
a real time basis.
B
During the welding, the LED for the welding sequence being carried out flashes.
2.
A series of welding operation is completed by the torch switch operation. (
6.6.3
-
Crater setting)
B
At the end of welding, the average value of the welding current and the welding voltage at the last second of the
welding sequence is displayed (result display) on the digital meter in a flashing mode. (except for the output at
crater-filler)
B
At the end of welding, the “Welding time”, “Total welding time”, “Total wire consumption”, “Heat input”, and
“Motor current” are displayed on the LCD panel.
B
The LED for the welding sequence changes to the light-up mode.
T I P S
Pressing any key on the operation panel during the flashing display will change the
indication to the set value.
The duration of flashing display can be changed by the internal function (F8).
When the welding time is short such as in the tack welding, accurate value may not be
displayed.
The displayed average value is processed by the software.
The display accuracy is equivalent to an ordinary pointer-type meter (equivalent to class 2.5).
Note that the value cannot be guaranteed as the control data for a measurement
instrument.
The wire consumption may be different from the actual wire consumption due to reasons
such as slipping of wire.
The displayed motor current value has been smoothed out. Therefore, the displayed value
may not be able to trace a sudden change in the motor current.
