WAT Gas Saver Products

THE PROBLEM:
An article published in Trailer Body Builders Magazine quotes an engineer from Praxair, a leading manufacturer of shielding gases, indicating the average fabricator consumes 3 to 5 times the gas theoretically needed.

A MAJOR CAUSE OF GAS WASTE Typical regulator outlet pressures are 25, 50 and 80 psi; pipeline pressures are 50 psi. However, the pressure needed at the feeder to flow the shielding gas though the solenoid, fittings and torch can be 3 to 5 psi. When welding is stopped, pressure increases in the gas delivery hose the output of the regulator or pipeline. When welding is started the pressure drops rapidly to that needed to provide the desired flow. The excess gas that built up in the hose is expelled in a very short time. PATENTED GAS SAVER SYSTEM A simple way to significantly reduce shielding gas waste is to employ a shielding gas hose with a smaller internal diameter.

Secondly, incorporate a flow restriction orifice on the wire feeder end of the gas hose. This has the benefit of additionally reducing gas waste and improving weld start quality. The p a t e n t e d G a s S a v e r S y s t e m ( GSS TM ) incorporates a small ID, heavy wall thickness hose with a flow restrictor built into the hose connection at the wire feeder end. The flow restrictor is sized to reduce the surge at the start but allows the operator to have full control of the welding gas flow rate.

PRODUCTION RESULTS The following is graphic presentation of test data from a fabricator in Columbia SC. The gas surge at the weld start was
reduced by 85%. They achieved a 50% reduction in total gas usage and significantly improved weld starts quality:

With a standard gas delivery system the surge flow rate is turbulent and mixes air into the shielding gas stream causing excess spatter and porosity. For this pressure piping application all welds must be UT inspected. The GSS restriction orifice eliminated problems caused by air in the gas stream and significantly reduced internal weld porosity at the start. Our website; www.NetWelding.com has much more information including published testimonial also showing shielding gas savings of up to 63%.

Youtube Videos describing the system are also available: www.NetWelding.com/Small_Video_1_Meg.htm BOTTOM LINE The WA Technology GSS has no moving parts to wear, or leak; no pressures to set or knobs to adjust. It’s unique, patented design maintains the gas pressure in the delivery hose. This allows a small amount of extra gas flow at the weld start to quickly purge air that is in the weld zone, torch gas cup and gas lines when welding is stopped. Maintaining the higher pressure also retains the systems ability to automatically compensate for varying pressure drops in the delivery hose and when the torch nozzle fills with spatter. The hose is made with a heavy wall thickness and fiber reinforced construction to provide a robust product. For most applications the GSS will pay for itself in gas waste reduction alone in a matter of weeks. Many thousands are in use, up to 100 feet in length.
