Invalid arm
The arm used is not compatible with the welding mode selected.
Current too low
1/ Check the weld
If the current obtained during a spot weld is lower than the expected value (6%), the machine dis-
plays the warning message «Low current, check the weld».
2/ Check the sheets
If the machine cannot deliver the current required, the error message «Low current, check the
sheets» is displayed. The weld does not happen and the fault must be skipped for the weld to happen.
Insucient air pressure
If the input pressure is insucient to deliver the tightening requested,
the machine beeps and displays, before the weld, the error message
«Insucient air pressure».
Pressing the trigger a second time is used to «force» the spot weld
using the available pressure. If the tightening recorded is insucient,
the machine displays «Low pressure».
«p low» is also recorded in the active report.
Pump priming
The «Pump priming fault» message appears when the cooling system pump is defused. Check the
coolant level in the tank.
Self-diagnostic
When the power is turned on, the machine performs self-diagnostics
and displays the results on the screen.
If no blocking error is present, this page is displayed for 3s and then
disappears. During this period, a short press of the MODE buttons, ▲
or ▼, leaves the CHECK pages displayed (results summarized on two
pages). A long press on MODE will exit the CHECK mode.
It is not possible to exit the CHECK pages if a blocking fault is detected,
except for a phase failure (see list below).
