ERROR HANDLING

2
FLEX 3000 Compact has a sophisticated built-in
selfprotection system. The machine automatically stops
the gas supply, interrupts the welding current and stops
the wire feeding in case of an error.
Selected errors:
Torch cooling fault
Cooling fault is indicated on machines equipped with
water flow kit in case of no circulation of the cooling
liquid due to faulty connection or choking.
Check that the cooling hoses are correctly connected,
top up the water tank and check welding hose and
branches. The cooling fault is cancelled by pressing
shortly on the –key pad.
Gas control fault
Gas fault exists due to a to low or high pressure on the
gas flow.
Make sure that the pressure on the gas flow is higher
than 2 bar and less than 6 bar, corresponding to 5 l/min
and 27 l/min.
The fault is disconnected by adjusting the manual gas
flow to 27 l/min. The gas fault is reset by a short
pressure on the -key pad.
Error log
All errors are saved in the machine error log in the menu
Service. The error log can be distributed, when inserting
a SD-card and pressing the following key pad:
The error log is now saved at the SD-card.
The error log can be reset when pressing the key pad
with the trash bin.

MAINTENANCE

The machine requires periodical maintenance and
cleaning in order to avoid malfunction and
cancellation of the guarantee.
WARNING !
Only trained and qualified staff members can
carry out maintenance and cleaning. The
machine must be disconnected from the mains
supply (pull out the mains plug!). Thereafter,
wait around 5 minutes before maintenance and
repairing, as all capacitors need to be
discharged due to risk of shock.
Wire cabinet
- Regularly, clean the wire cabinet with
compressed air and check if the grooves and
teeth on the wire drive rolls are worn out.
Cooling unit
Liquid level and frost protection must be checked
-
and cooling liquid refilled as required.
Drain the cooling liquid out of the cooling module
-
and welding hoses. Remove dirt and flush with
pure water in the tank and cooling hoses. Fill up
with new cooling liquid. The machine is delivered
with a cooling liquid of type propan-2-ol in the
ratio 23% propan-2-ol and 77% demineralized
water, which provides an anti-freeze solution up
to –9°C. (See article number in the spare parts
list).
Power source
Clean the fan blades and the components in the
-
cooling pipe with clean, dry, compressed air as
required.
- A trained and qualified staff member must carry
out inspection and cleaning at least once a year.
