Chain
1. 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.
2. Connect the pressure reduction valve on the gas cylinder.
3. Connect the gas hose to gas outlet
F8
on the valve and the gas inlet
F9
on
the machine.
4. 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.
5. Open the
F2
cylinder valve.
6. Press the torch trigger.
7. Adjust the amount of gas on the reduction gas valve (it is not a part of the
welding machine) by the
F7
adjusting screw.
8. Release the torch trigger.
8. 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.
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
A1
on "I".
To select the voltage use step switch
A2.
To select the current (that is linked to the wire speed) use the potentiometer
A6 (P1)
.
