General remarks
Utilisation for
intended purpose
only
The welding machine is intended to be used solely for rod electrode and TIG welding.
Any other use, or any use going beyond the above, is deemed to be “not for the intended
purpose” and the manufacturer shall not be liable for any damage resulting therefrom.
Utilisation for the intended purpose” shall also be deemed to encompass:
- the observance of all instructions in the operating manual
- the carrying out of all prescribed inspection and maintenance work
The welding machine is tested to “Degree of protection IP23”, meaning:
- Protection against penetration by solid foreign bodies with diameters larger than 12
mm
- Protection against spraywater up to an angle of 60° to the upright
The welding machine can be set up and operated outdoors in accordance with IP23.
However, the built-in electrical components must be protected against direct wetting.
Machine set-up
regulations
The venting duct is a very important safety feature. When choosing the machine locati-
on, make sure that it is possible for the cooling air to enter and exit unhindered through
the louvers on the front and back of the machine. Any electroconductive metallic dust
from e.g. grinding-workmust not be allowed to get sucked into the machine.
Warning! A welding machine that topples over can easily kill someone! Place
the welding machine on an even, firm floor in such a way that it stands firmly.
The welding machine is designed to run
on the mains voltage given on the rating
plate. The mains cable and plug are
ready-mounted. For details of fuse protec-
tion of the mains supply lead, please see
the Technical Data.

400 V~
The machine can be run as standard on a mains voltage of 400 V~ (+/- 20%). Thanks to
its +/-20% tolerance range, it can also be run on the 415 V~ mains.
Note! If the machine is designed to run on a special voltage, the Technical Data
shown on the rating plate apply. The mains plug and mains supply lead, and
their fuse protection, must be dimensioned accordingly.
Before starting to use for the first time, read the section headed “Safety rules”.
Never use the welding machine for thawing frozen pipes!
