Review: The pure quality in it
Review: Item is not as pictured. Picture as purchased shows a 0 - 30psi adjust range, perfect for that 3 - 5psi setting for a small welding tip, and for setting 20 - 25 psi for a small-flow cutting tip. That's why I bought this unit. As-received is the other picture, actually 0 - 200 psi, and good luck setting to low pressures accurately.

- Gas Service: Air, Oxygen, Inert Gas
- Delivery Range (psig): 5-125
- CGA 540 Connection: Oxygen
- Gauge Range Inlet: 4000
- Gauge Range Outlet: 200

### ⭐ Review

The regulated pressure gage reads 5 to 200 psi. I wanted the range as shown in the photo which is 0 to 30 psi. Otherwise it appears to be a good quantity item.
