•
Place the gas cylinder on the platform and fix it properly by the fixing
chain. We recommend using bolts and nuts to fix it more safely.
•
Connect the pressure reduction valve on the gas cylinder.
•
Connect the gas hose to gas outlet F8 on the valve and the gas inlet F9
on the machine
•
Open the F2 cylinder valve
•
Press the button Gas test 11
•
Adjust the amount of gas on the reduction gas valve (it is not a part of the
welding machine) by the F7 adjusting screw
•
Release the button 11 for digital

WELDING
For orie ntating adjusting of the welding current and voltage you can use
empirical relation U2 = 14+0,05 2. From that you can specify desired voltage.
8.1 SETTING WELDING CURRENT AND VOLTAGE
When the wire had been installed and gas had been set it is possible to start
welding.
The appliance must be plugged into the mains, the ON/OFF switch on "I".
You will find the ON/OFF switch on the rear panel of the welder.
To select the voltage potentiometer 2.
To select the current (that is linked to the wire speed) use the voltage
potentiometer 3
To modify the arc characteristic use the chope potentiometer 12.
8.2 WELDING MODES
Machines works in four modes:
