9. Trouble shooting
In case of malfunctioning check:
9.1
Presence of mains voltage
9.2
Integrity of cables and electrical connection wires
If the fault cannot be identified, send the equipment to the Manufacturer or to an
authorized technical assistance center.
Any repairs carried out on the machine by unauthorized personnel will cause the
warranty to be void.
ALARM CODES
When an alarm occurs, the welding process is interrupted (if in
progress) with the consequent possible degradation of the
material involved in the joint (fitting and pipes). Valsir S.p.A. declines all responsibility for
welding performed with material already used in processes in which alarm messages
have occurred.
The alarms are signaled by the flashing of the red LED and the simultaneous emission of
an acoustic signal (beep). Each alarm emits a precise number of flashes every 2 seconds.
The cycle repeats continuously. Press STOP to reset the error.

Alarm description
Cause
Solution
1
The machine cannot reach
the current required to weld.
The fitting load is too high
or the fitting circuit is
interrupted.
Replace the fitting.
Chek the cables’ integrity.
Check the power supply.
2
Interrupted circuit
The
fitting
circuit
is
interrupted.
Replace the fitting.
3
The requirements to start
welding are missing
The
fitting
has
been
disconnected. The ambient
temperature is out of
range.
Recheck
environmental
conditions
and
connections
4
Welding interrupted by the
user
The user has pressed STOP Start a new welding
5
Overheating
Consecutive weldings too
close together.
Protect the machine from
direct sunlight and extend
the cooling time of the
machine
6
Ambient temperature is too
high
Ambient temperature is too
high
Check the environmental
conditions and let the
machine to cool down
7
Short circuit of welding
terminals

terminals,
non-
compliant fitting
Replace the fitting.
