Mounting the gas cylinder
1.
At first, make sure that the valves of the bottle (if available) as well as the valve of the regulator
are completely closed (turned clockwise) to avoid a loss of gas due to accidental leaking.
2. Attach the high-pressure hose to the rear of the welder before connecting the other end to the
pressure regulator. To remove the hose, simply press it as well as the locking ring against the
hose connector. Keep pressing the ring in that direction and remove the hose by carefully pulling
it off the connector.
3. Ensure that your eyes are protected before removing the protective cap of the gas cylinder and
carefully attaching the regulator valve as gas might leak from the cylinder until the regulator
valve is attached properly.
4. Make sure to disconnect the regulator valve from the gas cylinder and to replace it with the
protective cap of the cylinder to prevent a loss of gas.
Configuring the regulator valve
Turn the gas feed regulation knob clockwise to completely close the valve and turn it
back (counter-clockwise) by ½ to 1 turn. This regulator valve is compatible with CO
is further equipped with a connector for Argon-CO
Figure 1: Use the transparent 2.4/4 mm hose to connect small bottles.
Figure 2: To connect large bottles, retract the transparent hose into the device and connect the end
with the quick coupler on the rear part of the 8 mm gas connection.
To loosen the hose from the quick coupler, the blue piece must be pushed towards the connection
while the hose is extracted.
