- TypeWelding Supplies
- Dual gas compatibility for Argon and Helium shielding
- Single-stage design delivers consistent outlet pressure up to 20 psig
- Argon flow rates reach 40 scfh for precise weld control
- Helium flow capacity extends to 100 scfh for high-heat applications
- CGA 580 inlet fits standard Argon and Helium cylinders
Argon and Helium Dual Flowmeter
The Harris 356-Ar/He-580 is a single-stage regulator with dual flowmeters for argon and helium shielding gases. It mounts directly to a cylinder with a female 0.965 in.-14 NGO inlet connection. The outlet uses a female 5/8 in.-18 UNF fitting. This unit is designed for welding operations requiring precise gas flow control.
Sustained Delivery up to 3,000 psig Inlet
The regulator handles a maximum inlet pressure of 3,000 psig and delivers a controlled outlet pressure up to 20 psig. Argon flow rates reach a maximum of 40 scfh while helium rates reach 100 scfh. Single-stage construction provides consistent output for continuous welding tasks without the complexity of multi-stage designs.
Single-Stage Regulator for Cylinder Mounting
This model suits welders who need a cylinder-mounted flowmeter regulator for argon or helium shielding gas. It is not intended for applications requiring two-stage pressure regulation or compatibility with gas types beyond argon and helium. The fixed outlet pressure ceiling of 20 psig defines its operational envelope.

Questions about this item
How much noise or heat does the 356-Ar/He-580 regulator produce when running all day?
The single-stage regulator has no moving parts or power source, so it generates no audible noise or measurable heat during continuous operation.
What must I already own to connect this regulator to my gas supply?
You need an Argon or Helium cylinder with a female NGO 0.965-14 right-hand thread and a hose or torch fitting that matches a female UNF 5/8-18 outlet.
Will the 356-Ar/He-580 work with my older welding torch that uses a standard 5/8-18 connection?
Yes, the outlet is a female UNF 5/8-18 thread, which is the common industry size for most existing TIG and MIG torch hoses.
