Adjusting Flow Rate
Art: A-05088_AB
Figure 6-2: Adjust Flow Rate
With the regulator/flowmeter ready for operation, adjust working flow rate as follows:
1. Slowly turn adjusting screw/knob in (clockwise) direction until the outlet gauge indicates the required
flow rate.
NOTE!
It may be necessary to re-check the shielding gas regulator/owmeter ow rate following the rst weld sequence due to
back pressure present within shielding gas hose assembly.
2. To reduce flow rate, allow the welding grade shielding gas to discharge from regulator/flowmeter
by opening the downstream valve. Bleed welding grade shielding gas into a well ventilated area and
away from any ignition source. Turn adjusting screw counter clockwise, until the required flow rate is
indicated on the gauge. Close downstream valve.
Shutdown
Close cylinder valve whenever the regulator/flowmeter is not in use. To shut down for extended periods (more
than 30 minutes).
1. Close cylinder or upstream valve tightly.
2. Open downstream equipment valves to drain the lines. Bleed gas into a well ventilated area and away
from any ignition source.
3. After gas is drained completely, disengage adjusting screw and close downstream equipment valves.
4. Before transporting cylinders that are not secured on a cart designed for such purposes, remove
regulators/flowmeters.
