Shielding gas, reducing valve
The reducing valve is screwed onto the gas cylinder and
connected to the machine by means of the gas hose. The gas
quantity is adjusted at the reducing valve. For this purpose
the machine must be switched on and the torch trigger or
"Gas manually“ button at the wire drive unit (QWD) must
be pressed. This function is designed as a button. If you
press this button once, the solenoid valve for the gas flow
is opened and the gas flow is interrupted by pressing the
button again. This enables you to set the exact gas quantity
by means of a gas control cone.
The function "Gas manually" is also available on the
operating module in the "Functions" menu. For safety
reasons, the gas flow is automatically interrupted after 2
minutes.
The shielding gas quantity depends on the process and
material and ranges between 8 and 16 l/min.
If the Qineo Champ Pro is connected to a central gas supply
system (closed circular pipeline), the reducing insert (bore
hole 0.6 mm) in the gas valve must be removed.
Wire drive unit
The wire drive rollers, wire guide unit and wire feed nozzle
are marked according to the wire size to prevent a wrong
nozzle size being used by mistake. This also applies to the
contact tips and liners of the welding torch, which are also
marked with the wire sizes.
When changing the wire drive rollers and gear wheels, force
must not be used to mount them on the gear shafts, e.g.
hammer or similar because this might cause damage to the
shaft axis.
The welding wire itself is threaded inside the wire drive unit
throughout the liner, the wire drive rollers, the wire guide
unit and the wire feed nozzle. The power source must now
be switched on.
The wire is transported to the torch by motor by actuating
the "Wire manually" button.
