5.1

Turning the Welding Unit on

After connecting the power supply cable to mains power or a gen-
erator, turn the welding unit on using the On/Off switch. This causes
Display 1 to show.
Then the screen changes to Display 2.
CAUTION in case of System Errors!
If during the auto-test that the unit performs at start-up, an
error is detected, a "System Error" message shows on the
display. When this happens, the welding unit has to be discon-
Caution
nected immediately from the power suppy and the fitting,
and it has to be shipped to the manufacturer for repair.
5.2

Connecting the Fitting

Connect the connection terminals to the fitting and check for proper
contact. Use terminal adapters if needed. The contact surfaces of the
cable connection terminals or adapters and the fitting have to be clean.
Dirty terminals may lead to improper welding and also to overheated
and fused connection terminals. Protect the cable connectors against
getting dirty at all times. Terminals and push-on adapters should be
considered consumables and, therefore, have to be checked before
every welding operation and replaced if damaged or dirty.
When the fitting is connected, the "No Contact" message (see Dis-
play 2) disappears.
5.3

Selecting the Pipe Dimension

When the fitting is connected, the pipe dimension, i.e., the diameter
of the parts that are going to be welded, is selected using the arrow
keys ñ and ò.
By pressing the START/SET key the selected dimension is applied to
the next welding operation.
The "Start ?" message means that the unit is ready to start the welding
process. Check the selected dimension again and if you find it to be
incorrect, delete it by pressing the STOP/RESET key. It is also deleted
if the welding unit is disconnected from the fitting.
5.4

Starting the Welding Process

After entering the component diameter, the parameters of the welding
operation based on it show on the dispay (see Display 4). The welding
process can be started using the START/SET key, when the "Start ?"
message is displayed and there is no indication of a problem.
Pressing the START/SET key will trigger a confirmation message "Pipe
treated?," which in turn requires a confirmation with the START/SET
key to start the welding proper.
5.5

Welding Process

The welding process is monitored for its entire duration applying
the welding parameters contained in the fitting code. The welding
voltage, the resistance, and the welding current are displayed in the
lower line of the screen.
5.6

End of Welding

The welding process ends successfully if the actual welding time cor-
