Using the C pneumatic clamp

Tighten the C-clamp using the locking lever and check that the screw between the arm and the clamp is correctly

tightened.

The clamping force is calculated by the machine, considering the force setting or the thickness of the sheets selected.

CLAMP SETTING MODE

The

key is used to enter the clamp adjustment mode. The clamp

adjustment mode allows the user to close the clamp and apply the
programmed force on the electrodes without any current flowing. This mode is
used to adjust the arms. The clamp will remain closed as long as the button
remains pressed; this allows the user to check the alignment of the electrodes
and positioning of the caps.

Press the

key for more than 2 seconds allows returning to the

STANDARD mode.

STANDARD Mode

This is the default mode when the machine starts. Quick and easy spot
welding by selection of:

The C-arm used

The Sheet thickness : it can vary from 0.60mm up to 3.0mm in steps

of 0.05mm.
When welding 2 metal sheets, enter the thickness of thinnest one.
When welding 3 metal sheets, enter the total of the 3 divided by 2.

The type of steel (standard steel, HSS steel, UHSS steel, BORON

steel).
- The up and down keys go through the parameters to modify sheet
thickness, type of steel, arm used. The + and – keys allow the
modification of each parameter.

Button (B) on the clamp allows the user change the thickness of the sheets to be welded remotely.
Button (A) on the clamp allows the user to spot weld with the selected parameters.

Before the weld: If the input air pressure is too low to reach the required electrode force, a warning will sound, and the
machine will display the error message “Pressure too low”. Pressing the button for a second time will force the execution of
the welding spot with the available air pressure.

After the weld: If the welding current measured during the spot is 6% less than the setting, the machine will display the
error message “Current too low” - the welding spot should be checked.

A message will be displayed at the end of every welding spot, showing the measured welding current and electrode force.
This message is displayed on the screen until a key on the control panel is pressed, or until a new welding spot is
performed, by pressing the button (A) on the clamp.

MULTI-sheet Mode

This mode allows the user specify the thickness and type of each sheet in an assembly of 2 or 3 sheets.

Using The up and down button (key definition diagram, (5) ) allows
selection of the parameters for each sheet. When the parameters for a
sheet are highlighted, the sheet thickness and type of steel can be
adjusted using the + and – keys (key definition diagram, (3) ).
The individual sheet parameters that can be adjusted in this mode are :

Sheet thickness : it can vary from 0.60mm up to 3.0mm in steps of

0.05mm.

The type of steel for each sheet : standard steel, HSS steel, UHSS steel,

BORON steel.

To activate the required sheet, press the up and down keys (button

definition diagram, (3) ) to highlight the required sheet ; then use the +
and – keys to select the thickness and type of steel.
