The advantage of using hydrogen flame for welding with welding speed, easy to control the flame, spot clean and beautiful, easy to use and so on. But also has a very good safety, in view of customers' security is very interested in the following discussion will focus on:

1. oxyhydrogen flame gas production are generally water welder gas in real time, to the gas pressure generated, generally 0.05mpa, far less than the high pressure cylinder pressure hundreds of times, and real-time gas is switched, not stored gas, when when there is surplus gas produced, and automatically stop gas production, gas is not enough time and automatically turn on when gas production. Therefore, the risk of explosion hydroxide flame tempering water welder produced hydrogen gas is much less than the risk of the cylinder.

2. oxyhydrogen flame water welder has a check valve to prevent back flow, i.e. flow of hydrogen gas flows from the machine direction is the direction of the flame gun, but not the reverse flow.

3. hydroxide flame water welder has a pressure relief valve in the event of tempering, backflow valve to prevent the flow of equipment inside the flame, while tempering the pressure is greater than 0.3mpa, pressure relief valve automatically outward pressure relief to prevent explosion .

4. The gas pipeline has a flame arrester, which ended ad hoc stainless steel powder metallurgy fire tube aperture of nanoscale, much smaller than the diameter of the hydrogen flame tempering, that flame can not pass such a small pores.

5. hydroxide flame tempered not like gasoline, liquefied gas as a continuous slow-burning, produces only a momentary pressure, the flame will automatically turn off the influence of pressure.

6. Hydrogen toxic and tasteless, there will not be any harm to the human body, hydrogen is very light, even if the leak quickly fled the outdoor atmosphere, does not form a cluster effect to the gasoline the same.

  Thus, using the oxyhydrogen flame used for welding is very safe. Two decades ago, no accidents occurred due to hydrogen tempering machine. We'd been hearing reports gasoline leak caused the fire, liquefied gas or natural gas leak residents require urgent loose.
