With more than 30 years of experience in the welding industry and over 8 years experience in trading industry, Mr. Raj Kumar Mittal, the founder & Managing Director of Mitco Weld Products Pvt. Ltd., initiated the brand “ARCON” in the year 1990 with a vision to provide welding solutions to the industry by virtue of quality welding products and associated services.
In order to further add to the customer experience, here we start the ARCON BLOG that will share our knowledge, experiences and views about welding product industry. This would everything & anything from which product to use, to tips on how to use the products more efficiently and also the latest trends in the industry.
So tune in to stay updated and make the best out of it.
A device for regulating a generally variable inlet pressure to an as constant as possible outlet pressure.
Means that a higher cylinder pressure needs to be controlled to a lower level required for welding, cutting and various allied activities. During this control process, the cylinder pressure, also called as inlet pressure, generally drops down with consumption. An ideal regulator is one in which the outlet pressure does not drop frequently with dropping inlet pressure.
SIZE: Look for a bigger size regulator, bigger the size means bigger chamber size that can store more pressure inside for delivering a uniform constant outlet pressure.
BRASS: Ensure that the pressure regulator is fully made of brass since brass has a good mechanical strength, non-corrosive and has the ability to absorb and release gas temperature easily.
Hardness: Ask the manufacture for hardness (hv) test report to compare the hardness of regulator connecting parts with the hardness of regulator cup and body which should be greater by 30 – 40%. This is so because the connecting parts are operative in nature and with prolonged use, the thread of cup and body, which are capital in nature, should not get damaged. Connecting parts, which on damage, can easily be replaced.
Filtration: The regulator must be equipped with dual gas filtration bronze filters. No gas is available without any dust particles which shall be stopped before the gas finally exits the regulator. It is so because dust particles in gas deteriorates the required results.
Diaphragm: It functions as the heart do in a human body. It must be soft yet durable. Softness increases its tendency to remain sensitive even at lower inlet pressure, say even at 8 to 10 bar. Softness measure should be between 70 – 80 Hv.
Pressure Gauges: They must be calibrated so that the readings are correct. Ask for calibration report from the manufacturer.
