Model HPI 904 is a single-stage cylinder regulator available in nickel plated brass (HPI 904) or chrome plated brassl (HPI 904C) barstock. Designed for applications where a slight rise in delivery pressure from full to empty cylinder can be tolerated.
APPLICATIONS:
▪ High purity gas applications for Non Corrosives Gases
▪ Gas chromatography
▪ Calibration gas, Purging, Blanketing
▪ Process analyzer gases
▪ Emission monitoring systems
FEATURES:
▪ Recommended gases purity levels up to grade 5.0 (99.999)
▪ 302 stainless steel diaphragm eliminates contamination from diffusion or outgassing
▪ One piece encapsulated seat design includes a sintered filter to protect the seat from particulate contamination
▪ Capsule seat with KELF-F (CTFE) sealing surface
▪ HPI 904 - Nickel-plated body, bonnet and fittings
▪ HPI 1904C - Chrome plated body, bonnet and fittings
▪ 1x10-8 mbar I/s He inboard helium leak rate to maintain gas purity levels
▪ 5 ports flexible configuration, 2 high pressure and 3 low pressure
▪ 1/8’’ NPT thread on the bonnet venting for safety
▪ Maximum inlet pressure: 300 bar (4350 psig) and 25 bar (362 pisg) for Acetylene AA version
▪ Cleaned for oxygen service

The TIG-MAX® works with a brush through which electrical current is passed. With the brush, a cleaning
liquid is absorbed and applied to the areas to be cleaned. The liquid is used to remove the iron oxide stains
formed during welding. The brush converts the electrical current into high temperatures, especially at the
bristle ends. The liquid, which is relatively harmless at room temperature, is heated by the brush to temperatures
at which it becomes much more reactive, resulting in an accelerated chemical action on the stainless
steel surface. Unlike pickling paste, the active ingredients of the cleaning fluid are not inherently harmful
to health. When used correctly, the fluids are non-toxic to the environment.
During the welding process, the pulse parameters are dynamically adjusted to keep constant arc length even when external disturbances occur(such as a changing wire extension length). As a result, the dynamic characteristics and arc stability are enhanced significantly. The uniform pulse frequency makes the welding sound softer, which greatly reduces the noise generated by welding. The strictly control on the one pulse one droplet transfer improves the welding quality and reduces the welding defects.The arc ignition adopts asynchronous curved surface acceleration control. The arc start energy is dynamically adjusted, which can quickly establish and stabilize the molten pool and improve the successful rate of arc ignition. Burn-back control utilizes controllable braking ball cancelling technology to improve the consistency of molten ball size. At the same time,the arc ignition and burn-back time are shortened, speeding up the welding cycle and improving production efficiency.
