Miniature Propane / Propylene canister regulator
This propane / MAPP gas regulator will fit many of the mini oxy fuel sets that are available on the market. An example of just a few would be the Oxyturbo 200, Rothenberger 120L and the CWS Mini Braze. Any MAP/P, MAPP, Propane or Propylene bottle that has been supplied from Worthingtons (USA) will have the same connection.
Typically these gas cylinders are either blue or yellow and come with a large thread of around 25.4mm diameter.
The outlet from our mini propane reg is G1/4 (1/4" BSP) with a left hand thread.
This thread is suitable for any 1/4 BSP flash back arrestors and any hoses fitted with 1/4 BSP nuts.
The output pressure from this regulator has a range of 0-2 bar. We developed our own version of this regulator as the cost of alternatives was far too high to justify. As such we source UK made pressure adjusting springs to ensure that you the customer gets the best possible flow setting, quite often it is the smallest of adjustments you need to make for there to be a flame which is perfect for your needs.
These small canisters are used very successfully for lead welding along with a whole host of brazing and heating applications. Lead welding is not the same as fusion welding.
Please be aware that it is not possible to fusion weld with any of the LPG dirived gases, this is due to the very oxidising flame. The maximum flame temperature excedes the melting point of steel by several hundred degrees even without adding in extra oxygen which increases the flame temperature by almost a further 1000C.
Also, please do not believe the mis-information concerning how hot some of the gas mixtures will burn at for example - oxy / propane will provide 2810C and oxy / propylene provides 2872C.
Oxy / acetylene provides 3106C which is the hottest commerciall available flame temperature and is able to do this with a neutral flame i.e. not oxidising.
