can someone steer me in the right direction to solve a problem with my mapp gas torch blowing out.

the gas cannister is new and has been kept in a relative warm place..the torch bit is also new..

i use it to melt gold/brass and it gets to a certain point and then blows out...i have the cannister at a 'horizontal to tipping down' level and the melting material is in a small crucible..

any ideas ? ... - .- -.

Stan, I think it needs to be more vertical, you want to burn gas not liquid.
That's how my torch works.

so do you think the liquid is stopping the gas from coming out evenly? ... - .- -.

That's what I was thinking, but I'm wrong.

I just had to nip to my workshop to get some tools so I tested my torch and it works i any direction. So sorry about that. It must be my plumbers torch on butane that doesn't work upside down.

So I don't know what is wrong, but as they are both new I would take them back. Range Rover 4.2 Supercharged 2006

My MAP gas torch does the same Stan, works perfectly when vertical to horizontal but tipping it over further, i.e. more upside down and it tends to go out. I just work around it but good to know if there is a solution or just the way they work. Jonathan

@jonathan, thanks for the confirmation...googling suggests the liquid in the bottle blocks the gas coming out... ... - .- -.
