2 Piece Dual Welding Gas Gauges Oxygen (CGA-540) and Acetylene (CGA-510) Regulators Combo

Seems to work just fine. I just needed the oxygen gauge but it was cheaper to buy both than to buy just one anywhere else.

They work. Pressure is steady, no climb or fluctuation while welding. Gauge needles appear to follow pressure changes smoothly. I can't claim they are accurate (or not), but low side pressures seemed about right. The machined, rounded surfaces that create the seal with the cylinder looked pretty bad...just rough work. I expected them to leak, but neither did, checked both with soapy water and by seeing if they held pressure for a few days. They did. So, no complaints, and they were cheap. I replaced my Harris regulators that I got as a gift in 1985, when I was 14. Will see how long these last. My old O2 regulator would slowly climb...the acetylene started to pulsate. My TIG doesn't pulse, didn't like it when my gas welder started to. But lasted almost 40 yrs.

Worked properly right out of the box. Excellent value

Working great, no issues.

Missing adjustment screw, broken guage

Work as expected, nice quality, helluva deal for the money

They work fine. In order to improve accuracy at my working pressures (4 PSIG), I removed the pegs in the gauges. Now I can read the true zero and thus get closer to a true 4 PSIG.Man, I hate buying stuff from China but the price was half of what I could find anywhere else. I just couldn’t justify a higher price for this little hobby project.

i was converting my Portasmithy over to the larger tanks. I was struggling to find the correct fittings to do that so just decided to order new gages. Worked perfectly and included the correct hose fittings.
