Adjusting Flow Rate

Figure 3-19: Adjust Flow Rate

With the regulator 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 flow rate following the first 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 by opening the down-

stream valve. Bleed welding grade shielding gas into a well ventilated area and away from any ignition source.

Turn adjusting screw counterclockwise, until the required flow rate is indicated on the gauge. Close downstream

valve.

3. Adjust regulator pressure adjusting screw to the required flow rate, indicated on gauge dial. (Refer to Figure

3-19)

The gas flow rate should be adequate to cover the weld zone to stop weld porosity. Excessive gas flow rates may

cause turbulence and weld porosity.

Argon or argon based gas flow rates:
- Workshop welding: 28 - 35 CFH
- Outdoor welding: 35 - 46 CFH

Shutdown

Close cylinder valve whenever the regulator is not in use. To shut down for extended periods (more than 30 minutes).

1. Close cylinder or upstream valve LIFT 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.
