Nicholas ★★★★★

Swapped this onto my S400 and the all-in-one regulator/flowmeter setup cleaned up my cart nicely. The flow tube and float are easy to read even at a glance while welding, and it held steady at 20 psig without drifting.

Ruby F. ★★★★★

The pressure-compensated design really shows when my tank pressure starts dropping — the flow stays right where I set it instead of creeping down like my old gauge did. Having the regulator and flowmeter in one compact unit also freed up a bit of space on the cart. Crisp, consistent argon flow every

Andrew L. ★★★★★

Swapped this onto my HTP S400 and the argon flow holds dead steady even as the tank pressure drops. The pressure-compensated design means I set it once at 20 psig and don't touch it again all day. Compact enough that it doesn't crowd the machine either.
