The welding machine mustn’t be used for pipe thawing purposes.
6- Place the machine away from the radio-controlled devices. The normal operation of the machine
may affect the operation of the other machines of this type in the vicinity adversely, which may
lead to injuries or equipment failure. Please read the section “Electromagnetic Compliance” in
this manual.
7- Do not operate this machine in temperatures below -10°C and above +40° C with a relative
humidity of above 70 %.
8- Do not allow unauthorized people to open the work covers of the machine and carry out any

having accepted the possible consequences in advance.
9- This is a dropping characteristic welding machine designed for tig welding and welding with
the 2.50 and 4.00 mm diameter welding electrodes with rutile and basic coating used for light
welding operations.
10- Not recommended for use with generators without output regulation, which could cause
operating disorders and malfunctions.
Duty Cycle and Overheating :
The duty cycle of the machine is the percentage rate of welding capability of the machine at the
specified welding current to 10 continuous minutes without resulting in overheating or interrupting
the work.
The machine is protected against overheating by the basic protection provided. When this protection
trips, the warning lamp on the panel lights up. When the machine is cooled to the safe working
temperature, the warning lamp goes off and welding is resumed.
