•
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
•
In case you use gas CO2 it may be needed to use suitable gas heater
(only above 6 l/min). Connect the heater to the F3 heater connector
(optional). Use type corresponding to voltage and current given on the
shield.
•
Open the F2 cylinder valve
•
Press the button Gas test X2 for digital, V12 for BASIC
•
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 X2 for digital, V12 for BASIC

WELDING
For orientating 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 V2 on "I".
To select the voltage use step switches V3, V4 - ALF 400, ALF 280 and 320
only V3
To select the current (that is linked to the wire speed) use the encoder V1.
8.2 WELDING MODES
Machines works in four modes:
•
continuous two stroke (2T)
•
continuous four stroke (4T)
•
spot welding
•
interval welding
