※1 Includes an outer diameter ∅8 hose fitting and a lock nut.

Features

• Ideal for pressure reduction and supply of argon, as well as its mixed gases, used as shielding gas for welding.
• Designed for direct attachment to argon containers.
• Optimally designed for argon supply in all parts, ensuring stable gas delivery.
• Preset for fixed outlet pressure, allowing easy flow rate adjustment with just the operation of the flowmeter valve.

※ If you intend to use mixed gases for welding (such as Sun Arc Gas, etc.), please contact our company.

※2 Hose fittings and lock nuts have been not included, so if you are using them for the first time or need to replace them, please order separately.
※3 It is a Bourdon tube-type flowmeter.
※4 Flowmeter specifications for 5-20 L/min (normal) have a surrounding temperature range of -10 to 40°C.
For carbon dioxide gas, it is based on a usage rate of 60% (10-minute rated) or less, and for MAG gas, it is based on 100% usage.

Features

• With a two-stage pressure reduction structure and an efficient heat exchange method, it solves the issue of flow instability caused by gas temperature drop due to adiabatic expansion, ensuring the stable supply of carbon dioxide gas and MAG gas.
• To efficiently absorb heat from the atmosphere, it has been equipped with fins that have a large surface area for air contact.
• Lightweight and efficient aluminum is used for the fins to enhance heat exchange performance.

※Cannot be used with siphon-type containers.

Flowsion FLA-PW-Ar

• Integrated bottle stand, argon pressure regulator, and twin-flowmeter, ideal for argon supply for pipe TIG welding.
• Suitable for use with two TIG welding machines simultaneously, not limited to pipe TIG welding.
• Equipped with a shield gas-specific water-repellent hose, ‘Sun Arc Super Dry Tube,’ as standard. Can remove moisture from the hose within a short time (3 minutes) of gas purging.
• Provides a pipe mounting cap for backshielding (optional). Contains a diffusion mesh inside the joint, ensuring proper distribution of shield gas to the welding area.
