the welding cable cycles to measure to ambient tempera-
ture and to adjust the welding time based on it.
All data that are relevant for the weld or for traceability
are saved to the internal memory and can be sent to a
USB stick.
The unit monitors the characteristics of its power supply
continuously. If one of these is out of tolerance, welding
is aborted or cannot be started.

Check-out and Operation
• To operate the welding unit, be sure that it is set on a
proper, level surface.
• Be sure that power supply/generator protection is 16 A
(slow blow).
• Plug the power supply cord into the mains power
supply or the generator.
• Read and comply with the User’s Manual of the gen
-
erator, if applicable.
5.1 Turning the Welding Unit on
After connecting the power supply cable to mains power
or a generator, turn the welding unit on using the On/Off
switch. This causes Display 1 to show.
Then the screen changes to Display 2.
Caution
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” mes-
sage shows on the display. When this happens, the
welding unit has to be disconnected immediately
from the power suppy and the fitting, and it has
to be shipped to the manufacturer for repair.
Important
The dust cap for the interface has to cover the port
during operation, in order to keep humidity and
contaminations away.
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 adapt-
ers 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
