Different sizes of torches and tips require different flow rates to operate properly. It is very important to understand the required gas flow for your process to ensure safe operation. High flow capacity flashback arrestors allow sufficient gas flow for larger heating and cutting tips. Additionally they have significantly longer service life because of their high flow capacity. A flashback arrestor can restrict gas flow if it is too small for the application, causing backfires, short tip life, poor quality work, and even equipment damage. Tip sizes and consumption rates vary for equipment from different manufactures. A good rule of thumb is to use a high flow arrestor for tip sizes larger than #4. However It is always better to size an arrestor based on the actual gas consumption. Flashback arrestor flow charts and technical service are available to help make the correct decision based on the equipment you are using. High flow flashback arrestors have a larger flame barrier with increased surface area to allow gas flow rates of 2 or more times a standard arrestor used at the same
SuperFlash / IBEDA two-gas adjustable gas mixer By Dave Marquard July 30, 2015 Westlake, OH – SuperFlash Compressed Gas Equipment, manufacturer of compressed gas safety and control devices, offers a two-gas adjustable gas mixer that allows blending your own shielding gases at almost any ratio and is simple to operate! Save Money and Get Better Shielding Gas! Often times, when buying pre-mixed gases, the mix purchased from the gas company is close but not exactly the formula needed for the application. Other times, pre-mixed gases aren’t used quickly enough and the gases will stratify (become un-mixed) in the cylinder. The best solution to this problem is to allow users to fully customize and mix the gases at the time of application. The SuperFlash Compressed Gas Equipment two-gas adjustable mixer allows blending your own shielding gases at almost any ratio needed to fit your process, requires no additional electricity, and is very simple to operate. Weighing in at only 7.5 lbs and using less than one cubic foot of space, the SuperFlash Mini-PGM is one of the most compact mixers available and will provide enough gas for eight welding machines at approximately 40-50 SCFH per machine. Each mixer is fully adjustable to allow you to customize and adapt your blends, and comes standard with a convenient mounting bracket so you can hang the mixer securely on a wall, machine cage, or any location you choose. In addition to providing complete shielding gas adjusta
Our friends at IBEDA, Germany created videos about the importance of using flashback arrestors while welding, cutting or in allied processes. Using safety devices, like those manufactured by IBEDA, on a global scale has led to a continually decreasing number of accidents in this industry. IBEDA did a great job of translating this report from German to English, and they created a short video on how flashback arrestors are tested at their facility. See their video below on how flashback arrestors are tested. See their PVGD demonstration
