I just refill my 12.5 kg Gas Cylinder and i connect the Gas Control Pressure back but it was not burning the way it was before, what can i do? Somebody with a help

What are you connecting you gas supply to? You don't offer much background. Pictures and/or a description of the (assuming) forge would be helpful. Without any other info, and if nothing else is different from the last time it performed correctly, I would suggest checking for dirt or debris in the connection. Disconnect the lines and check for obstruction.

From experience with a gas bbq grill, you may want to make sure that none of your valves, fittings or anything else got knocked out of whack while disconnected.

Welcome aboard Ayo, glad to have you. Please put your general location in the header you might be surprised at how many of the IFI gang live within visiting distance.

 

Modern propane bottles have safety fixtures to prevent a cut hose from turning into an out of control flame thrower so if you open the valve too quickly the safety will automatically stop or limit the flow.

 

That's all I can offer not knowing more about what you have.
