Manual 0-5346  

INSTALLATION, OPERATION AND SETUP 

3-31

 

NOTE!

All valves downstream of the regulator/ flowmeter must be opened to obtain a true flow rate reading on the 
outlet gauge. (Welding power source must be triggered) Close the valves after the pressure has been set. 

Installation

1.  Remove cylinder valve plastic dust seal. Clean the cylinder valve outlet of impurities that may clog orifices and damage seats 

before connecting the regulator/ flowmeter.

 

Crack the valve (open then close) momentarily, pointing the outlet away from people and sources of ignition. Wipe with a clean 
lint free cloth. 

2.  Match regulator/ flowmeter to cylinder. Before connecting, check that the regulator/ flowmeter label and cylinder marking 

agree and that the regulator/ flowmeter inlet and cylinder outlet match. NEVER CONNECT a regulator/ flowmeter designed for a 
particular gas or gases to a cylinder containing any other gas.

3.  Connect the regulator/ flowmeter inlet connection to cylinder or pipeline and tighten it firmly but not excessively, with a suit-

able spanner.

4.  Connect and tighten the outlet hose firmly and attach down-stream equipment.
5.  To protect sensitive down-stream equipment a separate safety device may be necessary if the regulator/ flowmeter is not fit-

ted with a pressure relief device.

Operation

With the regulator/ flowmeter connected to cylinder or pipeline, and the adjustment screw/knob fully disengaged, pressurize as follows:

1.  Stand to one side of regulator/ flowmeter and slowly open the cylinder valve. If opened quickly, a sudden pressure surge may 

damage internal regulator/ flowmeter parts.

2.  With valves on downstream equipment closed, adjust regulator/ flowmeter to approximate working pressure. It is recommend-

ed that testing for leaks at the regulator/ flowmeter connection points be carried out using a suitable leak detection solution or 
soapy water.

3.  Purge air or other unwanted welding grade shielding gas from equipment connected to the regulator/ flowmeter by individually 

opening then closing the equipment control valves. Complete purging may take up to ten seconds or more, depending upon the 
length and size of the hose being purged.

Adjusting Flow Rate

Figure 3-21: 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/ flowmeter 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/ 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.
