How to Set the Flow on the HL-0001
TL;DR: Close both flow knobs, open the cylinder valve slowly, then set each HL-0001 tube to the SCFH mark you want.
Before you open the cylinder
Check the cylinder valve and the regulator inlet are free of oil and grease. The gauge is marked USE NO OIL. Working temperature is 0–50 °C. Keep oil and grease off the regulator.
Fit the regulator
Fit the regulator to the argon cylinder and tighten the inlet nut. Fit a hose onto each hose tail. In the box you have the regulator, two flow tubes and two hose-tail fittings.
Open and set each tube
Close both flow knobs, open the cylinder valve slowly, and read the inlet gauge. The gauge is marked in psi and kPa. Measuring range is 0–25 MPa.
Open each flow knob and set the ball to the SCFH mark you want on that tube. Each tube is marked from 0 to 60 SCFH, and each has its own knob. Rated outlet pressure is 0.2 MPa. The HL-0001 is a single-stage, positive-action regulator.
