  • T-handle control allows precise pressure adjustment during operation

Single-Stage CGA-580 Regulator

The Victor Thermal Dynamics 0781-1408 is a single-stage welding regulator built for high-pressure gas control. It fits CGA-580 inlets and handles argon, helium or nitrogen in heavy-duty shop environments.

Sustained Pressure Control

A brass body and brass diaphragm maintain outlet pressure up to 750 psig during continuous flow. The single-stage design delivers consistent output without the complexity of a two-stage mechanism.

CGA-580 Interface Limits

The 0.965-14 NGO male inlet connects directly to standard high-pressure cylinders. Outlet uses a 1/4-inch male Swagelok fitting, so hose or manifold compatibility must match that thread.

Questions about this item

Does the single-stage design and 750 psig outlet pressure cause noticeable heat or vibration during extended welding sessions?

The brass body and diaphragm absorb heat from the gas flow; the single-stage construction has no moving parts that generate vibration, so the unit runs cool and quiet all day.

What hose or fitting must I already have to connect the 1/4 in male Swagelok outlet to my torch?

You need a 1/4 in female Swagelok fitting or an adapter that matches the 1/4 in male outlet on the regulator.

Will the 0.965 in.-14 NGO male inlet thread onto my existing CGA-580 cylinder valve without an adapter?

Yes, the CGA-580 inlet is machined to the 0.965 in.-14 NGO standard, so it threads directly onto a matching cylinder valve.
