User manual
USE OF EXTENSION LEADS
All extension cables must have an adequate size and section, relative to the machine's voltage. Use an extension lead that complies with national
safety regulations.
Voltage input
400 V
GAS CONNECTION
This equipment is equipped with two connections. A cylinder connector for the gas inlet into the station, and a torch gas connector for the gas outlet at
the end of the torch. We recommend that you use the adaptors supplied with your set to ensure an optimal connection.
RESETTING THE WELDING STATION
It is possible to restore the factory settings of the welding machine. When the product is in sleep mode, press the sleep exit push button (II-7) for 3
seconds. The product then displays «3», «2», «1» and then resets the unit.
