THE DIFFERENT WELDING MODES
For all the models :
The buttons (
keys + and –.
The button (FIG 2 -12) on the clamp is used to remotely adjust the welding settings (thickness, type of steel) :
- Long push : change of setting (to go from one setting to another)
- Short push : modification of the value
This button does not allow to change the arm on the screen. To change the arm (G1 to G2 for instance), the user must use the machine keypad.
Insufficient network pressure :
If the input pressure is insufficient to provide the correct pressure, the machine shows an error message before the weld «Insufficient network
pressure» . Pressing the trigger a second time is used to «force» the spot weld using the available pressure.
Low current :
If the current obtained during the spot weld is below the expected value (<6 %), the machine displays «low current» after the weld which means
that the weld must be checked.
In any case, a message is displayed at the end of the weld indicating the current and pressure measured. This message remains on display on the
screen until the user pushes a button on the keypad or carries on welding (FIG 2 - 11).
The welding conditions must be reviewed at the start of each new job. «Test» weld spots must be carried out on metal panels
or sheets similar to the new job being undertaken. Carry our two spot weld with appropriate space in between, in line with the
requirement of the job. Test the strength of the second weld. The test is successful if, when pulling the spot out, the panel breaks
and the centre is extracted. The centre must have a minimum diameter in line with the specifications of the make of the vehicle.
AUTO mode
In order to use this mode, do a blank spot weld (without any sheet/panel between the electrodes),as prompted on the display. Push the button (FIG 2
-11). The message «Do a spot without a load» is displayed on the screen. Push the button again to calibrate. Once the calibration is done, the machine
shows all the settings to zero, and is ready to weld. Close the clamp on the area to weld and weld automatically, without entering any parameters in
the machine. Every 30 spots, a new calibration will be required.
This mode can be used when using all arms except the G7.
NORMAL mode
Push the button
for 2 seconds to return to the AUTO mode.
MI300I 220V
or
) are used to select the settings that need to be adjusted. Each adjustment is done by pressing the side
This mode is displayed by default when the machine starts.
This mode is used to weld sheets/panels without having to specify any settings on the screen. The machine
sets the appropriate settings automatically.
This mode determines the welding settings based on the thickness of the sheets/panels and the type of
steel.
The settings that need to be set when using this mode are:
- Thickness of the sheets/panels, with a range between 0.60 mm and 3.00 mm.
When 2 sheets/panels are being welded together, enter the thickness of the thinnest sheet.
When 3 sheets/panels are welded together, use the total cumulated thickness and divide by 2.
- Type of steel (coated steel, HLE/THLE steel, UHLE steel, bore steel (BORON)).
When welding a mix of different types of steel, select the strongest one.
- Reference of the arm used.
