Huntingdon Fusion Techniques (HFT®), the world leader in gas weld purging procedures, has launched its tailor-made Argon Gas Feed Hose, designed to help keep welding zones purged of oxygen (O2).

In order to achieve a clean, oxide free and zero colour weld, the welding zone needs to be completely expelled of O2 when welding metals such as stainless steel, titanium and zirconium – so HFT have devised the Argon Gas Feed Hose to combat this.

The UK-based company have designed a selection of leak tight end fittings, provided for attaching an argon (Ar) gas regulator at one end of the hose, and a 12mm to 12mm quick connect fitting as standard at the other end. The quick connect fitting is designed to join up with all HFT Argweld® Weld Purging Systems.

Conforming to the British BS EWN 599 Quality Standard, the hoses each have a temperature range from -30oC up to 80oC, and a safety factor of three times working pressure - 20 bar or 300 pounds per square inch (psi).

The hoses can be supplied to all other gas tungsten arc welders (GTAW) and tungsten inert gas welders (TIG), with individual special fittings as required. The hoses are available off the shelf in standard lengths ranging from 5m-30m, but precise lengths can also be made to order with HFT’s new pressure end fitting compression tooling.

Luke Keane, Distributor Support for HFT, said, “These special, high quality Argon Gas Feed Hoses, which can also be used for transporting nitrogen (N2), come complete with end fittings, providing welders with a guaranteed leak tight method of feeding non contaminated argon gas to their weld zone.”
