This family of regulators used mainly with nitrogen can be used to purge refrigeration installations, inflate shock absorbers, inert large diameter pipes, etc.

We recommend mounting these regulators only on cylinders from B11 = 2 m3 to B50 = 10 m3 or on cylinder bundles.

Adjustable output pressure: 1 - 60 b

SPECIAL heater for the implementation of CO2 or neutral gas from a bottle in order to avoid cooling or freezing of the regulator and the installation.

Mounting on carbon dioxide bottle.

Helps heat and maintain CO2 in the gaseous phase.

3S Propane/Propylene shielded pressure regulator - 2.5 bar

Frost problem on your Ar/C02 regulator? The solution is to heat the gas to ensure a constant flow.

CO2 is a cold gas, it needs to be heated to use it for MIG welding protection.

French manufacture LE LORRAIN guaranteed for 2 years

External plastic tube with nut all graduations. Guaranteed French manufacturing

Delivery France and Europe in 48 hours.

The neutral gas large flow pressure regulator allows a standard pressure to deliver from 20 to 280 NM3/H. It can be used as a first pressure regulator, in neutral gas, to supply several dozen welding stations.

It is recommended to mount this regulator only on bottles of B50 = 10 m³ or on bundles of bottles.

Second stage pressure regulator for neutral gases (nitrogen, argon) suitable for applications using pure and inert gases. 

Equipped with a stainless steel diaphragm, output pressure adjustment from 0-35 bar.

Allows a very stable output pressure and a very precise adjustment.

Perfect for feeding laser cutting machines. 

Delivery in France within 24h

Discover the bottle regulator with pressure gauge from the EWM brand at HD Soudage. Compliant with ISO 2503, this single stage regulator offers precise and continuous adjustment up to 230 bar.

Equipped with a manometer to display the pressure, this quality product simplifies your welding operations

The DEI regulator for Argon/CO2 gas cylinders is the essential tool for professional welders aiming for excellence in their work while achieving significant gas savings. Don't let pressure spoil your welds; opt for performance, choose the 3-in-1 regulator.

Perfectly adapted for the use of pure and inert gases that need a very stable outlet pressure, as well as a very fine setting of this outlet pressure, equipped with a stainless steel diaphragm.

Perfectly adapted for the very specific power-supply of the electrical TIG/MIG welding units, the built-in adjustment wheel is graduated from 0, 6, 8, 10, 12, 15, 18, 22,26 l/mn with an extra maxi setting for a possible inerting operation (neutral atmosphere).
