Enclosure class
Application class
Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at
a certain load without overloading. The duty cycle is valid for 40° C.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects of 2,5 mm Ø and greater. Omitting second characteristic numeral.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.

OPERATION

General safety regulations for handling the equipment can be found on
page 32. Read through before you start using the equipment!
Please also read the operating instructions for the welding components, e.g. power
source and connect accordingly.
11.1

Connections

Tighten the connections for the torch carefully to avoid overheating the connection,
connection interference, mechanical damage or leakage of liquid or gas.
Connect water connections to the torch so that the red terminal is always connected
to the corresponding red terminal and the blue terminals are always connected to the
corresponding blue terminals.
11.2

Choice of electrode

By alloying the tungsten electrode with 1% to 2% lantha or cerium the electron
discharge is increased, which gives better striking and restriking and therefore
increased arc stability. Alloyed tungsten electrodes have a longer service life,
tolerate higher currents and are less likely to leave tungsten residue in the weld.
